Condescending and doesn't follow up.
Dr Reichelderfer is head and shoulders above any GI Dr. I have even seen, and before him I saw quite a few none of whom could figure out a treatment that would help me. After looking over my test results and meeting him for the first time within 5 minutes he suggested a course of treatment that changed my life. The other guys 4/5 of them over several years had figured out squat.
If you have a choice of GI docs to see choose Dr R, you'll be glad you did, he even sings as he goes about doing his appointments !
