  • I adore Dr. Raijman! After doing a lot of online research, I chose him to consult with about the balloon procedure. I chose him because he wasn't solely a weight loss doctor and is obviously an outstanding surgeon. I was extremely impressed with his qualifications. I attribute all my success with the balloon procedure to his skill as a surgeon. I had no problems whatsoever and would highly recommend him to anyone needing a gastroenterologist for any reason. He is a wonderful doctor!
  • Clear directions and concise communication. I have recommended Dr. Raijman to many friends, especially those with who have had prior bad experiences.

  • I was scared to bits about my procedure and the results and he was so gentle and kind…before my procedure he made sure to explain the process and the typical findings. Then when my procedure was over, he explained everything to me and gave me great news and even let me hug him in this Covid world!
