When Bergein F. "Gene" Overholt, MD, FACP, MACG, and his four partners opened the country's first state-licensed endoscopic ASC in 1986, they performed 20 procedures a day - on their busy days. Today, Dr. Overholt and his growing team of nine endoscopists in Knoxville, Tenn., perform more than 17,000 colonoscopy and upper-endoscopy procedures annually in their eight-room ASC/office complex.
