Patient Reviews
Oct 17, 2023
I met Dr. Gary Koenig in the procedure suite on Oct 4th. I had experienced GI and Urology issues for about 6 weeks. I I was physically miserable and frustrated. Dr. Koenig was kind, empathetic, and thorough. All done in a relaxed professional manner, with a sense of humor. His support staff was also excellent. Dr. Koenig helped identify that I had an undiagnosed hiatal hernia by reviewing tests and then completing the colonoscopy and endoscopy. I am glad to finally some answers, along with a solution and a plan. Very much appreciated!!
