Nice guy. Good doctor. i’m a nurse, so when i tell you he was thorough and competent, that’s exactly what i mean. Tickles me to have him out here in the sticks.
Very compassionate and knowledgeable making me feel confident my problem would be resolved. Highly recommend.
Dr Oelsner was especially polite and very personable. He listened closely to my issues, which was all over the place lol, but somehow figured out what I was implying. He set a few tests and I’m confident he’ll get me figured out. Also, he reminded me of my grandson. That’s a big plus. Thanks doctor
Dr Oelsner is very intelligent and competent and is a very good Gastroenterologist.
Everyone in the office were super friendly and helpful
He was very informative about the illness we are going thru .I felt very comfortable with his decision and feel that I have the right dr.for my issue. Thank you again dr
I arrived for my appointment and was put into an exam room quickly. Unfortunately, I then sat in the exam room for 1.5 hours waiting on the doctor to come in. Once he arrived, he explained everything thoroughly to me in a manner that I could understand. After, Katrina scheduled my procedure, of which the first available appointment was not until 3 months away.
Awesome experience He addressed all of my concerns and explained everything to me and was very patient and professional.
Very professional & knowledgeable about what I needed and concerned. He listened to my concerns.
Fantastic physician
