Review of Dr. Rengstorff

- |

Dr. Rengstorff is always on time for his appts, and both he and his staff are most pleasant and competent. I greatly value Dr. Rengstorff's medical expertise as well as his willingness to answer questions and discuss patients' concerns. I also appreciate that he responds in a timely manner to messages sent to him and shares test results as they become available. I am fortunate to have Dr. Rengstorff as part of my health care team!

Review of Dr. Yang

Dr. Yang has been my GI Dr. for years. She is outstanding! Colonoscopies, endoscopies, ulcers, etc. she has diagnosed my issues perfectly and treated them competently. She has a wonderful bedside manner yet you know she is supremely competent.

Review of Dr. Rengstorff

-

A previous GI doc prescribed a PPI, and I was not tolerating it well. My reflux was gone but I had suddenly become severely anemic, was falling down a lot, and was regurgitating daily. I saw Dr, Rengstorff for a desperate 4th opinion. He was not interested in my symptoms, just reiterated to stay on the med. When I asked for some alternative he "fired" me as a patient. I have never felt so alone or uncared for. I am happy to say I am now off that med & have no more reflux. I cannot recommend.

Review of Dr. Yang

- in san jose, ca |

My wife had an intestinal problem. Dr Yang performed a colonoscopy on her this week. I drove my wife to the Atherton Endoscopy Center where Dr Yang performed the colonoscopy. The front desk was so friendly. The nurses were quite sweet. After about one hour, the nurse escorted my wife to me (in the waiting room). My wife told me the entire procedure was extremely smooth. Dr Yang found 2 polyps and removed both -no pain, no discomfort.. She was amazed with how superb Dr Yang was.
