ABC’s Extreme Makeover: Home Edition

The Long Family thanks all the contractors, volunteers and contributors for helping make the dream of a new home a reality for a worthy Middleburg family. The ABC Team selected Carrie Prewitt, a high school volleyball coach who lives in Middleburg, Florida, as the recipient of a new home. Prewitt became the legal guardian of one of her players, Ashley Brewer — along with Ashley’s two younger sisters, Taylor and Gina — after the Brewers girls’ parents passed away.

J.A. Long, along with co-builder ARK Remodeling & Construction of Gainesville, transformed Prewitt’s small, run-down house into a new home within one week.
