Our philosophy? If you want to improve your external impact, focus within—on people, process, and power dynamics. Because vision and values only become alive when our words align with action—and power and voice are equitably shared.
Taking an “inside-out” approach that identifies root cause issues, we help you improve your internal communication and processes, build structured project management and content planning frameworks and create human-friendly, data-driven communication strategies that engage and grow your audience.
Meet the Practice
The Cosgrove Group was founded on a core belief: true organizational and social health require collaboration, connection, and consensus rather than coercive top-down hierarchies.
“Cosgrove” is an Irish surname meaning “victorious.” Named in honor of the founder’s great-great-great-grandfather, William Cosgrove—who fled County Mayo to Merseyside, England during the Irish Famine—The Cosgrove Group embodies a family legacy of standing against systemic oppression and advocating for the vulnerable.
We combine human-centered advocacy with PMP® project management and strategic communications to transform organizational health and promote social change, from the inside out.
Sarah Márquez, PMP

With a background that spans crisis advocacy, corporate communications, and small business ownership, Sarah brings an “inside-out” perspective to organizational health—ensuring that internal systems and values align with external image, mission, and community impact.
