What can I say about Dr. Jelinek other than she the best gastroenterologist I have ever had. She is very thorough with my care and she listens to me. She takes extra steps to make to make sure that I'm all right and she never misses a thing that's what I love about her. When I came into the procedure room she greeted me with smiles and giggles. We were all joking around and that eased my nervousness and that's what I loved about everyone there it was really nice to be greeted with many many smiles. Dr Jelinek is definitely a keeper and I plan on keeping her thank you very much Dr. Jelinek I really do appreciate you and your crew. You guys did an awesome job.
