Deondre C. Marshall was born in Miami, FL, and raised in Little Haiti. He is an individual who is versatile in the arts of cinematography and poetry. For the past four years, Deondre has filmed and edited music videos, short films, and feature films. He is eager to advance to the next level of his art which is videography. His mission as a returning Public Allies member is to build capacity for his organization, and build his artistry with videography. He seeks to create content through visual storytelling in communities around Miami.

He is seeking an Associate of Science degree for Film Production at Miami Dade College North Campus. His photography has been published by the Miami Herald in 2020. After mentoring teenagers for the past 3 years with the nonprofit organization Urgent, Inc., he received a plaque for “Outstanding leadership through peer mentorship.”

Deondre chose to pursue the art of visual storytelling because he feels that it is the best way to communicate what story can be told by anyone, especially while living in an era where digital media dominates the market. He believes any living person or a body of people has a story to tell and he wants to be the person behind the lens to help make that happen.

Deondre joins Guitars Over Guns as a member of Public Allies Miami.

Born in South Florida to Nigerian immigrant parents, Starve Marve is an exemplar of the first-generation American. Teacher by day, musician by night – consistently torn between American and Afro cultures, Starve finds his only balance in the sounds he creates. Greatly encouraged by the individuality of Outkast, Marve traverses cross-genre territory influenced by road trips with his DJ father’s collection of Bob Marley & Fela Kuti, the Boom Bap 90’s he grew up within, and the 8O8’s that have taken over.

Born and raised here in Miami, FL, I have been passionately giving back to the after-school community since I was 15 years old. I have journeyed through numerous programs as both a student and mentor.

I like to describe myself as a very layered individual who loves fun and to focus. A self proclaimed Urbanologist, I LOVE reading, going to the beach and listening to an array of music. I studied English Lit in undergrad and Urban Education as a Grad.

2 fun facts about me are…
I am secretly great at karaoke.
I am an awesome WRITER who hopes to publish my very own book one day.

My name is Sarah Stephens but I’m also known as SJ or Sarah Jean. I was born is colorful Colorado, traveled a bit and have called Miami home for five years. I’ve been passionate about music since I first found rhythm as a toddler. I’ve been singing since I could talk and never wanted to stop.

Although I studied vocal performance formally for over 10 years, my formal education is in Cultural Anthropology. I graduated from the University of Northern Colorado and ever since have loved visiting cities around the world, finally ending up in Miami. I was fortunate enough growing up to have music classes both in school and outside of the classroom. I’m proud to share music with children in Miami schools. The best part about the gift of music is that it is meant to be shared, and sharing builds community.

I’ve had many amazing opportunities in life, including working with children in Brazil, Colorado and Miami. I’m currently a singer and songwriter for myself as well as for a band in the Miami area. I love to create and share stories with others through music and to watch what happens when people connect. As long as there is something left to say, there’s a song to sing.

Since the release of his mixtape Tale of Two’s City Vol.2 in 2008, Add-2 has been captivating listeners’ and tastemakers’ ears and imaginations with his unique blend of hip hop, jazz and soul. Through his acrobatic wordplay, his detailed storytelling and his no holds barred social commentary, Add-2 has emerged as a respected voice of clarity in a chaotic world.

After years of perfecting his craft, Add-2 has earned a list of accomplishments many emcees dream of. Having appeared on MTV 2, MTV U, FUSE, HOT97, and Shade 45, he is currently sponsored by major clothing company LRG, has performed alongside legendary hip hop band The Roots and is one of Common’s favorite new emcees. Common had this to say:

“Add-2 […] is somebody who seems like he really cares about the culture and cares about uplifting people, and that’s inspirational to see; I get inspired by people that do that. No matter what age you are or where you’re from, when you’re really trying to do something good, I see that and I’m like, ‘man…’  It’s a good reminder of what I should be doing.”

Add-2 grew up on Chicago’s notorious South Side surrounded by an environment that exposed him to many harsh realities at an early age, from gang violence to drug use and poverty. Born the second of three kids, Add-2 found refuge in his writing, determined not to suffer the mistakes of his friends and peers. Through song, Add-2 began telling his story – a story that he felt wasn’t told often but was desperately needed. A story about survival.

After releasing several critically acclaimed projects such as Save.Our.Souls, More Missed Calls and Between Heaven And Hell, Add-2 gained the attention of Grammy Award-winning hip hop producer 9th Wonder. In October 2013, Add-2 officially signed to 9th Wonder’s music label, JAMLA Records.

Walker Moseley was born and raised in Boone, North Carolina, a small town located in the Appalachian mountains. After graduating from North Carolina State University in 2010, he moved to Miami to complete an AmeriCorps year of service with City Year. Upon completing his year of service with City Year, he accepted a Program Manager position with the organization and oversaw City Year’s implementation in Allapattah and Liberty City public schools.

While in graduate school, Walker was a Lipman Fellow with the Wharton School of Business and worked for the Committee of Seventy, a think tank focused on ethical governance, where he launched a successful pilot program that engages juniors and seniors in Philadelphia high schools through elections-focused service learning.

Andrew DeMuro has long balanced a “double life” between music and education. As an undergraduate at the University of Miami’s School of Education & Human Development, he logged over 700 hours in Miami’s low-income schools and communities, including a culminating student- teaching experience at Booker T. Washington Senior High School which earned him UM’s “Excellence in Student Teaching” Award in 2012. He also put his musical talents to work at the renowned Frost School of Music, and became the first freshman non-music major selected for the Jazz Vocal 1 group. 

After graduation, Andrew moved to Chicago to join Teach For America, and was employed at an all-boys charter high school on the city’s West Side. While teaching, Andrew developed a passion for shifting and rebuilding adult mindsets around students from marginalized backgrounds, particularly those with disabilities. He also started his charter network’s first sustained extracurricular choir, UPliftment, which twice earned superior ratings at the Illinois “Trills & Thrills” Music Festival at Six Flags: Great America.

In an effort to better combine his two passions, Andrew joined the Guitars Over Guns family in the fall of 2015 as a founding mentor and site coordinator at Evergreen Academy Middle School on Chicago’s South Side. During this time, he wrote and played music extensively with his acoustic trio, The Shades – a trio University of Miami alumni – and was honored with the unique opportunity to represent “Team Adam” on Season 11 of NBC’s The Voice.

Following his time on The Voice, Andrew immediately returned to the Windy City to begin working as Chicago’s founding Regional Director for Guitars Over Guns. While managing  the experiences of nearly 350 students, fifteen mentors, and four local school partners, he was recognized by his alma mater as one of the University of Miami’s “30 Under 30.” Through his work with Guitars Over Guns, Andrew hopes to continue to strike a balance between his two passions.

Chad Bernstein is a husband and father of four amazing kids, the co-founder of Guitars Over Guns, and a professional musician who has been instrumental in the evolution of the “Latin Funk” sound of Miami. Through the universal language of music, Chad galvanized the artist community to use music as a bridge to reach and empower Miami and Chicago’s most vulnerable youth. 

Chad received a Doctorate of Musical Arts degree from the University of Miami in 2012, turning the focus of his academic studies to Guitars Over Guns in his dissertation, “The Effectiveness of Music Mentoring for At-Risk Youth Through the GOGO Program,” published in 2012. This paved the way for Guitars Over Guns’ research-based methodology and set the stage for Chad and his father, Bob, a Chicago investment professional, to collaborate on the organization’s creation in 2008.  Chad took on Guitars Over Guns as a full-time career upon graduating (while continuing a rigorous performance schedule) and was named CEO in 2012.  Today, Guitars Over Guns has a $2,000,000 budget with 90 musicians serving nearly 1,000 students a year in 30 sites between Miami and Chicago. In April of 2015, Chad was honored as a CNN Hero for his work and has since been featured on the Steve Harvey Show and in People Magazine. Most recently, Chad received the Ruth Shack Leadership Award, an honor held in Miami’s highest regard.

Chad remains one of South Florida’s premier Latin, jazz, and funk artists. While trombone remains his primary instrument, he also plays conch shells, sousaphone, and keyboards with multiple bands.  He performs most prominently with the Latin Grammy-nominated Spam Allstars, with whom he has toured throughout Europe and the U.S., and the highly popular Miami-based Latin-funk band, ¡Suénalo!, the inspiration for Guitars Over Guns.  He has also worked with Pitbull, Shakira, will.i.am, Natalie Cole, Frank Sinatra, Jr., Chaka Kahn, John Legend, Phil Ramone, and many more. 

Chad is currently serving his second term as a Governor on the board of the Recording Academy (GRAMMYs), where he co-chairs their Education Committee. In addition to his work with The Spam Allstars and ¡Suénalo!, two groups that have pioneered Miami’s signature Latin-Funk sound, Chad also works with James Brown’s long-time musical director, Pee Wee Ellis, and Latin pop star, Jencarlos Canela.

Chad released his first full-length CD, Suite for 2nd Lieutenant, in 2012, an original body of work he wrote in dedication to his brother, Max Bernstein, upon his first deployment to Afghanistan as a U.S. Marine Corps combat platoon leader.  He released that CD after his brother completed his very distinguished service as a Captain and Company Commander in 2014.
