About our Practice

Gastrointestinal Associates of Cleveland was founded by William F. Buchner, Jr. in 1989 and has been providing excellent GI healthcare to our community since that time. As our community grew, so did our practice, with the addition of Paul Brundage, D.O.in 2006. Dr. Brundage who served 10 years in the Army, has added much needed care to our patients. In 2001, Shelia Trew, NP became the first Nurse Practitioner at GI Associates. Shelia has been with our practice since that time and treats patients as family, providing the best care to our patients. Barton (Nick) Nakdimen, NP joined our practice in 2021 and brought to the practice another avenue for excellent patient health care. Kari Williams, NP joined our practice in 2018 and has been invaluable providing excellent GI healthcare to our patients. We are blessed to continue to have an increase in patient population and saw the need to add John King, NP to our practice. John is providing excellent patient care with our patients.

Our physicians perform procedures at both Tennova Healthcare and Novamed Surgery Center.
