"I met Dr. Gulinson last week for the first time. He let me tell him my about my stomach issues I've been having for about 4 months. I wasn't rushed and he listened. He had quite a few questions he asked me afterwards. I felt he was thorough and I have my next appointment scheduled. He was recommended to me by both my mom and aunt."

"I would honestly have rated this experience a 5 except that the scheduler assured me that if I arrived at my check in time I would be seen at my appointment time and out in 30 - 40 minutes. This was simply not the case. I waited for 75 minutes after my check-in time for about. 10-15 minute visit. Thankfully I really liked Dr Gulinson and his manner overall."

"I would give Dr. Gulinson 10 stars if I could! 20! He is kind and understanding - truly an expert in his field. I've been seeing him for about 7 years and he's seen me through some hard times. His approach is maybe a bit on the conservative side, which I really appreciate. My last appointment I was in bad shape and struggling, well on my way to a full on flare-up. He listened to me, took probably extra time to talk about my options and made sure I understood. Suggested some changes to medication and talked me through the changes. Dr. Gulinson and his office staff are wonderful - above and beyond what's "in the job descriptions" for sure. I recommend them whole-heartedly and without reservation."

"The prep for a colonoscopy is so difficult that it leaves you with fear. When I arrived I was instantly put at ease. The nurse that did my iv was great,as you only stuck me once with no pain. That never happen with me. I was taken back where I again saw Dr Lam and the ansthesist. Went to sleep easily awoke to very good news. The facility was better than going to the hospital. I give all very high marks. L. Bonney"
