Born and raised in Alexandria, Virginia, Clark Mercer spent his summers growing up exploring on the Northern Neck of Virginia where his father’s family is originally from. His late grandfather, U.S. Air Force Colonel Hundley Mercer of Whitestone worked the waters of the Rappahannock as an oysterman with Clark’s great uncle, Walter, who was a manager of the Menhaden Fish Factory at Taft Beach in Whitestone.
