Hal Stallworth

Hal Stallworth, Legislative Accountability Coordinator
Growing up in South Carolina, Hal played in the rivers of Columbia. He learned to hunt below Congaree National Park, and was delighted by the beaching porpoises on Captain Sams Spit. He developed a deep love for these special places; a pride in them. His career working in commercial real estate, property management, sales and fundraising has taken him to many places around the world, yet nowhere compares to these wonderful South Carolina treasures. In his role at CVSC, his love for our amazing natural surroundings has grown even stronger and deeper.
