Kind, very caring, goes the extra mile to make sure his patient is well and if any sign of complication he rules them out. Doctors who truly care are hard to find. Well Dr Oelsner is the doctor you want to go to if you want feel like you are important.

Dr Oelsner is an amazing provider. He's very patient focused and kind. He's also up on all things GI... old and new. I'm grateful that he got the consult to see me while inpatient. I'll be moving forward with him as my Gastroenterologist. He's a 10 star class act on my book.
