“We met Dr. Singh after my husband was diagnosed with End-Stage Liver disease by another doctor. We switched to Dr. Singh because he was so kind, compassionate, and he spoke to us on a level that we could understand. My husband’s case was very difficult due to many other health conditions he had, but Dr. Singh never gave up on him for almost two years until he received a new liver. I highly recommend Dr. Singh to everyone I know who is in need of a GI Specialist. Thank you Dr. Singh!”


– Susan D. in Ray, Michigan

Dr. Singh is a very kind, thoughtful and patient doctor. He takes his time listening and addressing any concerns and fears you might have. I was very grateful to have found such a caring doctor! I also have recommended him many times to family, friends…etc. That’s the best compliment you can give a physician and also to show your appreciation for their expertise.
