M & J

Dr. Taunk

Dr. Taunk has been my Gastro Doc for the past 15 years and his sincere, professional care has never waivered during the years. I would travel thousands of miles for his professional care, and will continue to recommend his services to any and all family, friends, and fellow athletes I meet.


Dr. Taunk

I wanted to take the time to share my experience with Dr. Taunk and his staff at Advanced Gastroenterology Associates. I had to have colonoscopy and endoscopy this year due to some discomfort issues I was having. The staff was very courteous and calming. Dr. Taunk was very professional and explained the procedures and outcomes to me. I am very happy with their staff and services and would definitely recommend him.


Dr. Taunk

My husband, became Dr. Taunk’s patient in 1996. Because we found him to be thorough and extremely competent, I selected him when I developed symptoms covered by his specialty. He diagnosed two chronic conditions and explained the treatments. Over the years he has kept me functioning well. I really appreciate his complete explanations of both the conditions and the best treatment methods. Another plus in being his patient is his office staff. They are pleasant, courteous and helpful. I am very glad we learned about Dr. Taunk and happy to continue to be his patient.


Dr. Taunk

I just want to thank you ever so much for helping to improve my life. For the past two years, I have been suffering a series of gastro challenges. During that time, I have had many tests, consultations with several physicians and different treatments, none of them worked. After my initial consultation and single testing with you, I am pleased to tell you that the diagnosis and treatment that you selected has made all the difference in the world. Now, I can have a normal life. I am grateful to you and your staff.
