Dr. Callahan is one of the best doctors and surgeons I have ever seen. He is down to earth, always willing to explain and make sure you understand everything. So far I am 2 weeks post op and have never felt better. I super appreciate him …

Dr. Callahan and his staff were informative and made the consultation, surgery and follow up easy. Would highly recommend using Tennessee Surgery Center.

Dr.Callahan saved my life in more ways than one. First when he preformed my Gastric Bypass and gave me my life back with my husband and children. The again when I developed an internal hernia that attempted to kill my small intestines. I trust him with my life 110%
