i was told that the doctor would contact me with a video link, and i never was contacted. when i called their office, i was only promoted through their automatic voicemail that i could contact someone in case of emergency. so i didn’t have my appointment, and i have no idea how i could have

She was great! She listened everything and explained everything to me nicely. Understood my concern right away. I would definitely see her again.
June 24, 2020Ozlem B.Verified patient
I liked her questions and felt she was really trying to help me. Most doctors office visits you feel rushed, this was not the case with dr Legung. I have hope she will get to the bottom of my stomach issues. Merry Christmas, Kathleen

It was great experience
March 18, 2022Naunit S.Verified patient
So rare to find a doctor who takes the time to explain things, and works with you to find the root cause of your health issues, not just prescribe to relieve symptoms. Dr. Rengstorff was right on time for my visit and addressed all my concerns.
January 27, 2022Initials hidden
Dr Rengstorf's office visit was a good experience. it was decorated with comical gastro related things like a poop emoji plushie in the waiting room and punny Christmas cards with all the doctors dressed up. you can tell they enjoy what they do. this was further backed up by my actual visit with Dr. R. he was very clear and concise and super friendly. was very happy to answer any questions I had. would recommend

Very patient and knowledgeable GI doctor who reviewed all my conditions in details before and I had an efficient video call that was started on time without any wait, and quickly allowed me to set up upper endoscopy in just a few days.

Couldn’t ask for a better doctor! Dr Rengstorff is warm, personable, and patient. I never once felt rushed, and all my questions were answered thoughtfully and clearly. I would recommend Dr Rengstorff without hesitation.
April 7, 2021Neha D.Verified patient
Dr. Regnstorff is a really good listener. This makes him stand out amongst other fellow medical professionals. He does a great job of treating each patient the way we should be treated, not just one of the products he has to follow a certain protocol to take off of the production line asap like some other doctors do.
Han S.Verified patient
She listened, explained some useful things, and scheduled a follow up. I felt very cared for.
