"Dr. Gulinson is great! I’ve had 2 procedures (colonoscopies) performed by him and his team. I will be having my third in July. I have every confidence that it will go as well as the others. Dr. Gulinson’s office staff are kind and efficient—no long waits either. The doctor explains what will happen during the procedure and what he does if polyps are found. He answers questions and puts me at ease. The prep is easy and much better than friends have experienced elsewhere. You drink a tasteless laxative with a clear drink of your choice. Not a fun time but necessary since my family has a history of colon cancer. Dr. Gulinson has a calm, kind bedside manner. I highly recommend him as does my PCP. 👍"
