Previous two doctors I saw could not figure out what was wrong with me. First doctor said I had chronic pancreatitis which is incurable and that I will always be in pain and need to watch what I eat. I had to cut 90% of food out of my diet. Pain continued. Went to second doctor, did blood tests and ultrasound again. Both came back normal. That doctor said there is nothing wrong with me. After 4 extra months of constant pain, I made an appointment with Dr. Rengstorff to see if I can get an MRI that I knew would cost me a fortune. After I described my pain, the doctor said that it sounds more like I have a peptic stomach, not pancreatitis. He prescribed a special antacid that cost pennies and literally 10 min after taking first pill all pain was gone! I could have continued to suffer for years have I not gone to this doctor. He is a genius.
Doctor was good listener and understands the problem deeply and suggest prescription . It was very interactive . Highly recommended.
No wait time to see the doctor. Once I started describing symptoms he knew what was wrong right away. Very informative at the next steps in my diagnosis and I was able to get better through his recommendations
Dr. Rengstorff interviewed me with utmost precision and patience. He made sound conclusions and proposed a course of action that is well balanced. I developed high confidence in Dr. Rengstorff during the visit (my first one to this specialist.)
