Board of Directors

Sarah Hays
Chair
Committees: Executive (Chair); Finance & Development; Governance; Communications & Events; Organizational Empowerment ad hoc

Sarah was born and raised in South Carolina, growing up in Mullins and eventually moving to the Charleston area for college in 1999. With the exception of some stints abroad, she’s made Mt. Pleasant home with her husband, Josh, and two sons, Caleb and Mason. When she’s not advocating for safer infrastructure, Sarah is putting on all women triathlon events in the Carolinas, known as She Tris. As a triathlete herself, she loves empowering women through this sport and cheering them all across the finish line. Aside from races, she also enjoys traveling with her family and friends. Safety for run/bike training is what drove Sarah to join the Charleston Moves board, but the desire for street equity and community engagement is what fired her up to become the chair.

Before NP Strategy, Morgan served as the Communications and Outreach Specialist for the Berkeley-Charleston-Dorchester Council of Governments for three years. In this role, she played a key part in the Lowcountry Rapid Transit project, South Carolina’s planned bus rapid transit system, where she led numerous outreach efforts with diverse stakeholders.

Morgan brings expertise in community engagement for infrastructure projects to the Charleston Moves Board, fueled by her passion for supporting the livability needs of the Charleston communities where she was raised. Morgan earned her Bachelor of Arts in Public Relations from the University of South Carolina in 2020 and her master’s degree in Strategic Communication from Purdue University in 2024.

Morgan Hughey, Ph.D.
Committees: Communications & Events

Morgan was born and raised in the Upstate of South Carolina and moved to Charleston in 2017. She lives with her partner, Abby, and their daughter, Nora, and dog, Griffey, in the North Central neighborhood of downtown Charleston. Morgan is a professor of public health at the College of Charleston where she enjoys teaching students and conducting community-based research on promoting communities that encourage active living, such as access to quality public parks within walkable and bikeable neighborhoods. Morgan enjoys outdoor activities like swimming, hiking and exploring parks, playing sports and planning her next travel adventure. Morgan greatly values the work of Charleston Moves because safe places for walking, biking, and public transit create healthier communities and more vibrant places to live; she also bikes or takes the bus to work and wishes for that to be a safer option for more Charleston residents. She really enjoys how Charleston Moves highlights the work of the organization and Charleston community during Mobility Month (May!).

Michelle Martin
Committees: TBD

Michelle grew up in rural Indiana where her love for community involvement was nurtured at an early age from 4-H, FFA & Junior Leaders. Her family moved to Georgia in the mid-eighties and after high school she attended Francis Marion College in Florence, South Carolina, before moving to Charleston in 1995. Her professional career began as a fundraiser for a non-profit and grew into a marketing role while being active with Charleston Junior Chamber of Commerce, and later becoming a REALTOR, which ignited her entrepreneurial spirit.

Today, Michelle is a Freelance Digital Marketing Consultant while also flexing her creative talents as an Interior Designer. Married with pets, Michelle and her husband Andrew enjoy sports, swimming, DragonCon and riding bikes: “Any time we can leave our car at home reinforces why we love living here.” Having experienced first-hand the lack of bike lanes, unsafe crosswalks, and knowing citizens have lost their lives attempting to cross the North Bridge, is how Michelle became involved with Charleston Moves. First she was an active volunteer before being invited to become a Board Member. Michelle uses her voice to reinforce, spread awareness and gain support for the mission of Charleston Moves.

Mary Martinich Tweel, PLA
Committees: Communications & Events (Chair)

Mary, a native of Austin, Texas, relocated to Charleston with her husband Andrew, a Marine Scientist, ten years ago, drawn by the charm of a coastal town. They have two energetic boys, Miles and Leo, who keep them active with sports of all kinds especially soccer. As a Landscape Architect at SeamonWhiteside, a comprehensive landscape architecture and civil engineering firm, Mary brings a unique blend of creativity and expertise to every project.

In her free time, she enjoys yoga, baking with her kids, and diving into her latest book club read. Her passion for landscape architecture aligns seamlessly with her advocacy for Charleston Moves, where she promotes safer, more walkable streets in and out of the office. One project that Mary is excited about is the Ashley River Crossing and biking from her house on James Island to the Peninsula.
