Saw Dr. Ganser for a carcinoid tumor in my lung. Initial exam he spent time with me and explained everything and answered any questions.. In the hospital his bed side manner was wonderful. Saw him again for a post op visit. He has to be one of the most kind, compassionate doctors you would ever meet. I would recommend he and his staff to anyone. He is truly "THE BEST"!

Dr. Ganser is a guardian angel. Everything you would dream of and hope for in a Dr. and surgeon. He's sincere, concise and experienced. He did my 90 year old fathers surgery and it was a great relief knowing he was his Dr. Ironically he was mine also for an appendectomy 2 years ago and was phenomenal. He's the Best!!!
