When I went in service It was quick service and everyone was very positive and polite. My doctor was very welcoming and allowed me to explain how I was feeling.

I went to Dr. Gulinson twenty years ago for Hep C. He cured me of that with Interferon, and I just went back to see him again after all these years and he is still a very knowledgeable and an extremely efficient Doctor.

I have been a patient of Dr Gulinson for a few years. He has been an advocate of my health and helps keep me on track. I would recommend him for your gastrointestinal needs.
