About Dr. Steven Abbadessa

Operating a private practice in St. Louis, Missouri, Dr. Steven Abbadessa focuses on rectal, colon, hemorrhoid, and genital wart care. He founded several clinics in the area, including the Colon Rectal Health Center, the Hemorrhoid Care and Treatment Center, and the Genital Warts Treatment Center. Board certified as a proctologist and surgeon, Steven Abbadessa, D.O., treats most of his patients in his office, without necessitating difficult or expensive surgeries. He combines traditional treatment with alternative medicine for hemorrhoid relief, and his office offers patients a line of fiber supplements that help to maintain a healthy colon.

Board certified in proctology, Dr. Steven Abbadessa has earned more than 25 years of experience as a physician and 20 years as a proctologist. Before beginning the practice of medicine, he attained his D.O. from A.T. Still University of Health Sciences’ Kirksville College of Osteopathic Medicine and received his undergraduate degree from Drury College.

A dedicated family man, Dr. Abbadessa enjoys spending time with his wife, his three children, and his two Labrador retrievers. Growing up a part of the restaurant business in Macon, Missouri, provided him with a discerning palate. He considered the Pear Tree Restaurant in Bevier one of his favorite eating establishments until it was destroyed by a fire in 2012.
