Brian Martin (He/Him)
ExComm Member, Term: 2024 -2025


A resident of the city for the past 13 years, Brian Martin has a heart for Hartford. His passion stems from the fact that Hartford is nearly 18 square miles, and though replete with innumerable religious institutions, nonprofit organizations, and government agencies, people and entire families continue to fall through the cracks. Brian has always had a love for nature. Growing up in Brooklyn, NY, he lamented the fact that he had limited access to the great outdoors. Summers were spent in North Carolina, where he could explore with abandon. And that’s what he wants for Hartford youth: The benefits of learning to recognize and appreciate the nature in their own neighborhoods and connecting them with programs that take them beyond the confines of the city. Currently, Brian is completing his undergraduate studies at Trinity College, and works on campus in the Career & Life Design Center as the Career Programming Intern. Additionally, through the local nonprofit, Hartford Communities That Care, Brian works at New Visions Alternative School as the Youth Empowerment Coach. And he serves as Community Organizer for the national nonprofit, Trust For Public Land.
