"Both my husband and I have been seeing Dr. Mark Gulinson for years, and we have found to to be absolutely wonderful, caring, and concerned. He has always spent as much time as we need with us. We love the fact that he is affiliated with a private facility for colonoscopy and endoscopy, rather than having to go to a dirty, germ-filled hospital, where you can pick up any kind of bacteria or disease. We would never choose anyone else! Thanks for everything, Dr. Gulinson!"
