Leaving on a High Note: Mr. Warren’s Coda

As The New Century School school year draws to its inevitable end each year, one thing has become more and more clear with each passing one: it is much less an end or closing than actually a beginning or opening. Students don’t stop where they are—they move up to the next phase with all of the new challenges, delights, triumphs, and learning it will entail.

This ascension is not limited to students, however—in fact, all who pass through its halls take with them what gifts they enjoyed here to be applied in new ways to new things. (You probably know where this is going.) And that’s just what is happening with the TNCS community’s beloved Martellies Warren, who leaves TNCS on a soaring, high note.

Opening Bars

“I went to The Saint Paul’s Schools for Career Day earlier this year, and I shared my journey—growing up in the projects, not having a lot of money,” Mr. Warren said. “But my parents instilled in me early on that I was going to college no matter what. That was a driving force for me.”

The visit was transformative—not just for the students who sent him a care package full of handwritten letters afterward about how his words affected them, but for Mr. Warren himself. “They were so inspired. That day changed something in me, too.”

Career Crossroads

“I always tell students they’re going to come to a lot of crossroads. My hope is that they always follow their gut,” Mr. Warren said. One such crossroads came in his own life when he chose a vocal scholarship to Morgan State University over a partial scholarship to Berkley. “Had I listened to my band teacher and not followed my gut, I don’t know where my life would be. But I chose to go with what I knew.”

For Mr. Warren, music has never been just a subject—it’s been a calling. “I learned music at a very early age, and it paved the way for me. It gave me opportunities,” he said. One such opportunity is singing with Anthony Brown and Group Therapy, a Grammy Award-winning gospel group.

And, although maybe not quite as glamorous, his time at TNCS is another. From the moment he stepped into TNCS in 2012, he began shaping a vibrant music program where none existed before. “I built the department here—when I got here there was no music department. I’ve kind of done it all, and it’s been an amazing ride.” He fondly recalls concerts that brought the community together—including one that moved him deeply: “My mom, who’s passed on, loved this school. She would ride in on her scooter to see my students perform. They always made sure she had a good view. This place holds special memories.”

Over the years, he has directed concerts, coached vocal technique and various instruments, taught choral harmony, and brought countless students into the world of music. He also spent many years as a Lead Montessori Teacher in the primary classroom as well as directing summer camp and other administrative positions. But, as he puts it: “Music is my passion. If I’m not doing music all day, the part of the day where it’s not music feels like work. For a creative, that’s painful.”

Called Back to Music

With what started as nothing more than a talk at a different school, Mr. Warren began to realize it was time to realign with this passion. He had returned to TNCS after a couple of years away in 2022 as Director of Music and Extended Activities. This year, he re-donned the role of teacher.  “I felt like I was spinning my wheels being back in the classroom. I was losing my way a little. It felt disorienting.” Although he certainly gets all the credit for the two amazing concerts this year, he just wasn’t able to do music full time. “I need to be challenged and motivated. When I no longer feel that, I know it’s time for a shift,” he said.

Interestingly, as these truths shone brighter and brighter to him, his stars started to align—big time. When Saint Paul’s reached out to ask if he knew anyone who might be interested in a position as full-time music instructor, he recounts, “I told them, ‘I might be interested,’ and they thought I was joking. But I said, ‘It’s time—I need to get out and spread my wings.’”

And the harmonies don’t end there. “The head of school there is from Montgomery, Alabama, where I’m from. His mom and my mom even went to the same college. Then he asked what church I attended and said, ‘Stop it. I came out of your church.’ That’s alignment—it can’t get any clearer than that.”

Next Movement

Not surprisingly—despite hundreds of other applicants—Mr. Warren was immediately invited to campus for interviews, tours, and more. In fact, he was even asked to lead a seventh-grade music class with no warning. Also not surprisingly, he rose to the occasion: “I taught them ‘Amazing Grace,’ and within 15–20 minutes, they were singing in three-part harmony. The five arts chairs were just sitting there amazed.”

And just like that, he’ll now be teaching the boys’ middle school in a choral room located inside the campus chapel. “Good acoustics! I’ve got a huge room, an office downstairs—I’m excited. It’s a beautiful campus, like a small college.”

Mr. Warren’s Legacy

Of course, such wonderful news for him is bittersweet for us—we couldn’t be happier for him nor more bereft for ourselves, right? But, being as loved and appreciated as he is, the happiness for him takes right back over, and that’s across the board. He truly leaves on a high note.

There are no hard feelings. That’s important to me. I’ve stayed too long before—and things turned sour. I didn’t want that to happen here. I’ve run out of runway. I don’t want to say I’ve outgrown the place, but in the sense of my career, I have. There’s no upward trajectory from here, so I have to go where I can continue to grow and be challenged.

At 46, Mr. Warren knows he’s far from done. His goals for this next “movement” are ambitious and beautiful. They include:

  • Further developing my expertise as a choral director, specializing in the cultivation, and development of young voices
  • Pursuing a masters and doctorate degree in music performance/education
  • Spending more time cultivating and perfecting my own craft
  • Performing and touring professionally, and finding more opportunities to live life more fully!

And so, Mr. Warren leaves TNCS as its music director with his head high and heart full. “This place has enriched me just as much as I’ve enriched the students. This is home—it always has been. That’s why I came back.”

He’s especially proud of moments where his students demonstrated professionalism and courage, such as when they performed “America the Beautiful” at the Baltimore Blast game. Another choir had mistakenly been booked to sing the same song. “Most kids would have had a meltdown. But our students stood their ground, sang with heart, and got a standing ovation. That’s a testament to what we do every day.” And let’s not forget that amazing performance from Wicked at the spring concert! “Those kids blew me away. They don’t even realize the magnitude of what they accomplished,” he said (speaking for anyone who was there and saw it).

Encore!

Even as he moves on, Mr. Warren plans to keep the music alive between the two schools. “Don’t be surprised if I pop up next year with my choir to do a concert here. Or have kids from TNCS visit me at Saint Paul’s. I want that connection and collaboration to continue.”

Meanwhile, we get 1 more week with Mr. Warren this summer for Music Theatre Camp, in which campers will put on Friends or Foes: A Wickedly Exciting Journey of Self-discovery!

As he prepares for his next act, Mr. Warren reflects with gratitude. “This school will always be on my mind and in that place in my heart.”


In addition to several blogs about Mr. Warren and his work linked above, here’s more music! More fun! (And lots more wonderful memorable photographs!)

TNCS Spring Concert 2025: Enjoy It! Have Fun!

Those words of encouragement were delivered by TNCS Music Director Martellies Warren to the TNCS K–8 choir (see the “Wade in the Water” video below). It worked—the singers were having a ball on stage, as you’ll see and hear! More importantly, this theme of encouragement has defined Mr. Warren’s career at The New Century School. He might demand a high level of professionalism from his young performers to put on a terrific show, but the care, belief in them, and mad skills he rewards them with in return far exceeds what he asks. He is one of a kind.

But first, a few reflections. This Spring Concert was special (they all are, but this one in particular). It was beloved Mr. Warren’s last at TNCS, as he makes a career move that will allow him to more fully embrace his passion and gift for music. Although this farewell (not goodbye, he assured everyone!) is difficult, the entire TNCS community will be happy for his good fortune and wish him the best. We’ve had him for 15 years . . . guess it’s time to share this amazing human being with other lucky folks! 

But that’s far from the only reason this concert deserves extra attention. The song selection, the singing, the enthusiasm—all of that is down to Mr. Warren’s ability to put on a great show. TNCS students worked hard to get ready, and it showed. Speaking of working hard, the stage decorations were crafted by none other than Mr. Warren himself!

And we would be remiss not to mention how nice the auditorium looked, thanks to TNCS art teacher Adriana Boucher’s efforts. It was great to see how the projects she described for us earlier in the year came together!

Now let’s get to the music!

Preschool Concert

After some lovely words by Preschool Director Terriann Lane about all that Mr. Warren did to prepare for this show, TNCS primary students took the stage. They sang songs in English, Mandarin Chinese, and Spanish, bless their multilingual little hearts!

(Apologies if you hear giggles in the background—it was difficult for audience members to maintain composure amid so much cuteness and joy!)

Spring was very much in bloom on the TNCS stage today!

Elementary & Middle School Concert


Next it was time for TNCS K–8 students to display their vocal chops, and they truly wowed the audience! Mr. Warren demanded—and got—primo performances for this one! But first, Ms. Simonetti had some lovely thoughts to share.

Music is the ultimate expression of togetherness…it’s amazing to consider the collective effort and synergy it takes for individuals to unite and transform separate parts into a single, powerful whole that creates something greater than the sum of its parts. Music is the ultimate expression of togetherness… it’s amazing to consider the collective effort and synergy it takes for individuals to unite and transform separate parts into a single, powerful whole that creates something greater than the sum of its parts. Today’s performance is a reflection of that collaboration—please join us in celebrating the music our students have worked so hard to bring to life.

As in several years past, Mr. Warren brought in some well-known friends to help out with some lovely backing music: the Benjamin Brown trio! There’s more! TNCS Head of School Ann Marie Simonetti, in addition to all of her gajillion other contributions, actually made the adorable tie-dye shirts worn by the elementary and middle school students, with help from her trusty staff. This added a some creative nuance to the Spring-themed performance.

Ms. Simonetti closed the show with another heartfelt address to the audience, followed by a student gift presentation to Mr. Warren.

Before the concert, I spoke about the incredible power of music—how each person must listen, trust, and respond to one another to blend their individual parts into a harmonious whole. TNCS has been truly fortunate and tremendously grateful to have the guidance and passion of Martellies Warren, who brings us together not only in music but also in spirit and community. As his focus turns more fully toward the passion that most nourishes his soul—his love for music… we want to take this opportunity to express heartfelt gratitude to Mr. Warren…… At a time when music and art are increasingly cut from schools, they remain at the heart of the educational experience we believe in at TNCS. Mr. Warren has not only raised the bar beyond what we thought possible, but has cultivated remarkable growth in our students—nurturing talent, building confidence, and helping them achieve a level of excellence that continues to amaze us!

We will miss you, Mr. Warren—you better return often! Or else!

Together We Can: TNCS’s Black History Month Celebration 2025!

At The New Century School, “creating an inclusive environment is at the heart of everything we do.” So said Head of School Ann Marie Simonetti to open last night’s Black History Month Celebration. It will be lost on exactly no one just how poignant those few simple words were at this . . . beleaguered moment in U.S. history.

Commitment to Inclusion in Challenging Times

Last night, however, was all about the hope, joy, and community that TNCS represents. And what a way to close out Black History Month! As she continued her opening remarks, Ms. Simonetti set the tone for the evening by reaffirming TNCS’s unwavering dedication to fostering an inclusive environment:

Our core values and portrait of a graduate reflect our dedication to honoring the diverse identities, experiences, and backgrounds of our students, families, and staff. As a school community, we strive to prepare students to thrive in the increasingly diverse world. Understanding history, embracing different perspectives, and standing for equity and inclusion are not just ideals, but necessities. In times when efforts to diminish equity and the truth of history are making headlines, it’s more important than ever that we remain committed to recognizing and preserving the contributions of individuals from all backgrounds and ensuring that every story is valued, and every voice is heard. Dr. Maria Montessori called on us to provide conditions that will allow our children to give us a true picture of the society of the future. Tonight’s celebration is one way that we do just that.

She then asked the audience to stand, as TNCS students raised their voices in song, and TNCS’s auditorium rang for the next hour with powerful voices, moving poetry, call-and-response, and joyous songs commemorating Black History Month.

Celebration Through Expression

Parents and staff watched with pride as TNCS students demonstrated not just their artistic talents, but their growing understanding of equity, justice, and the importance of amplifying diverse voices. We cannot overstate how much team effort went into making this event a resounding success, from the student-made art festooning the walls, to TNCS Music Director Martellies Warren’s rousing—and beautiful—choral selections, to all of the behind-the-scenes-but-no-less-appreciated support from teachers and other staff.

The Show Must Go On. . . 

When TNCS K–8 students took to the stage (in high style), the enthusiastic response from audience members confirmed that our community treasures these opportunities to come together in celebration of our shared humanity and diverse heritage.

Lift Every Voice and Sing

First up, the “Black National Anthem”!

Some Very Special Extras 

But that wasn’t all. TNCS students read excerpts from Amanda Gorman’s “The Hill We Climb” and spoke on themes central to Black History Month, like the importance of the Divine Nine.

The grandmother of a TNCS preschooler even came up to read Amanda Gorman’s Change Sings, backed by slides showing the beautiful illustrations by Loren Long.

And TNCS favorite LaTriese Sussman led the audience in a Call and Response adapted from Rebecca Parker’s poem “Choose to Bless the World.” Ms. Simonetti confessed that she knew this moving celebration was going to bring her to tears at some point, and this beautiful, whole-community participation piece did the trick.

Reflections . . . and Looking Forward

In a time when difficult conversations about race and history are sometimes avoided, TNCS embraces them as essential to developing compassionate, informed citizens who will shape a better world. This Black History Month celebration wasn’t just about looking back—it was about moving forward together with greater understanding and purpose.

This commitment feels particularly significant today. While some governmental policies appear to be rolling back progress on diversity initiatives and historical accuracy in education, TNCS stands firm in its belief that understanding our complete history and embracing multiple perspectives are essential for preparing students to navigate our diverse world. The light of understanding that shone so brightly during our celebration continues to guide us forward—illuminating not just where we’ve been, but the more inclusive, equitable world we’re working to create.

Together, we can.

TNCS Winter Concert 2024 “Sleighs”!

As part of its commitment to The Arts, The New Century School takes student performances to the next level! On Thursday, December 12, TNCS elementary and middle school students performed choral selections in three languages, all under the brilliant tutelage of TNCS Musical Director Martellies Warren with assistance from language teachers Joan Cui and Rafael Gonzalez.

This year’s winter concert warmed hearts even as temperatures dropped outdoors. Some special touches this year include a QR code printed on the concert program that provides translated song lyrics as well as TNCS’s first-ever Holiday Pop-Up Shop! Oh, and a very special rap session at the end—another TNCS first! Maybe there was extra magic in the timing of this performance (12/12/24)?

Martellies Warren Is Back in the Classroom at TNCS!

Martellies Warren is nothing short of a legend at The New Century School. His history with TNCS is nearly as long as the school itself (scroll to the end for earlier blog posts about this rich history). As one of the longest-serving staff members, Mr. Warren has been an integral part of TNCS’s growth and evolution over the years. He joined TNCS in its early days, in the second year of the school’s operation at its current location. He vividly remembers the excitement of those early years and fondly recalls his fellow staff members like Mrs. Lawson and Ms. Lazarony.

Well-Rounded Approach to Education

Throughout his tenure, Mr. Warren has witnessed and adapted to numerous changes within the school. He’s very proud of the overall development of TNCS’s educational approach. His ability to embrace change while maintaining his core values as an educator has been crucial to his longevity at the school.

Over the years, Mr. Warren’s role at TNCS has evolved. He has worn many hats, from (the world’s best) music director to administrator, and now as the lead teacher for the K-2 cohort. This varied experience has given him a unique perspective on the school’s operations and needs.

Long-Standing Commitment to The New Century School

Mr. Warren’s commitment to TNCS is evident in his approach to the school’s ongoing development. He emphasizes the importance of adapting to change and finding beauty in the present moment. “As someone who’s been here and has seen this school go through so many changes, I had to let go of what it used to be,” he reflects. “If you continue to try to measure today’s metrics with what it was, which is a whole different time with a whole different set of variables, then you’re going to always long for something that used to be.”

Despite the challenges that come with growth and change, Mr. Warren remains optimistic about TNCS’s future. He takes pride in the progress he sees, particularly in the Montessori preschool classrooms and what TNCS Preschool Coordinator Terriann Lane is doing there. “It takes time,” he says, “but we are really getting there. It’s a great place.”

As TNCS celebrates its 15th year, Mr. Warren’s deep connection to the school community continues to shape his teaching philosophy and his interactions with students, parents, and fellow educators. His long-standing commitment to TNCS, combined with his diverse educational background and musical talents, make him a unique and valuable asset to the school community, and he brings a wealth of experience and enthusiasm to his role.

Early Career and Discovery of Montessori

His journey in education began in traditional classrooms in Baltimore City, but a pivotal moment occurred when he discovered Montessori education. The sight of students engaged in this alternative learning environment at Julia Brown School in Columbia, MD, took his breath away.

Throughout his career, Mr. Warren has embraced various educational approaches, including online middle school teaching in Baltimore County. “I think this diverse background makes me a more well-rounded educator. I can take some of those aspects of that pedagogy and I can apply it now to a more traditional classroom setting,”” he said.

Finding Joy in the Classroom

In his current role, Mr. Warren teaches English Language Arts, Global Studies, and Math. He also continues to share his passion for music, teaching it to most grade levels. His day is a bustling mix of core subjects and music instruction, which he manages when his homeroom students are at Chinese and Spanish lessons (taught by colleagues).

Mr. Warren’s love for his current age group shines through. He appreciates how his K-2 students are independent enough to tackle tasks on their own, yet still seek his guidance and support. “All day I’m hearing ‘Mr. Warren!’ which is wonderful because I’m happy to be of service to them,” he shares with a smile. Describing a recent lesson, he enthuses, “Today we’re working on ‘Fundations‘, which is a curriculum that we’re doing this year. We went into a whole lesson on what a foundation is and discussed how we have to build on something that’s stable and how we view their learning the same way.”

Double Life: Educator and Professional Musician

Beyond the classroom, Mr. Warren has another claim to fame—he’s a successful gospel musician. While his students might not be fully aware of this aspect of his life, it’s a significant part of who he is. As part of Anthony Brown & Group TherAPy, he’s performed alongside industry giants like Kurt Franklin and Yolanda Adams, an experience he still finds mind-blowing.

Mr. Warren credits his own teachers for inspiring his dual career path. He fondly remembers Henry Terry from Montgomery, AL, who first recognized his classical voice and introduced him to competitions and advanced musical training. This experience underscores his belief in the profound impact educators can have on their students’ lives.

Embracing Change and Progress

Mr. Warren reflects on his journey with gratitude. He’s thrilled to be back in the classroom, focusing on what he loves most—interacting with children. “Being in the classroom doesn’t feel like a job,” he says. “My heart leaps when I’m in there.”

Looking Ahead: Winter Concert and Beyond

Looking ahead, Mr. Warren is excited about the upcoming winter concert, a cherished school tradition he’s preparing for with his usual enthusiasm. His positive outlook and dedication to his students continue to make him an invaluable (and much beloved!) asset to the TNCS community.
