"Dr Raijman has been my wife’s gastroenterologist for several years but this was my first visit and procedures based on her recommendation. Both the initial office visit and the subsequent endoscopic procedures were handled quickly and efficiently and without any discomfort. Dr Raijman’s bedside manner puts you at ease and his post examination discussion of the results with suggestions for future well-being were both thorough and helpful. Accordingly he has my sincere recommendation"

His staff there is extremely friendly and helpful too! The only bad thing is that he is in Houston. Other than that everything was great!"

"Dr. Raijman has been my gastroenterologist since 2004, when I had a complicated condition concerning a stone which was stuck in a bile duct with an opening too narrow for it to pass. He performed an ERCP to remove the stone and widen the duct. Then I was referred for gallbladder surgery, and I haven’t had any gastric problems until now. I am currently under his care again to determine the cause of an abdominal pain. Not only would I consider Dr. Raijman the MOST knowledgeable gastroenterologist in Houston, but also a compassionate one. During my recent appointment his comment was the following: “ I took care if you then (2004) and I’m going to take care of you now.” So thorough tests were ordered and with Dr. Raijman’s superb diagnostic skills, I’m sure I will be well cared for."

"I first met Dr Raijman 6 years ago when he was recommended to us by my husband’s gastroenterologist as the “best” in his field. My husband was diagnosed with endocrine pancreatic cancer. Over the last 6 years, Dr Raijman has performed 6 necessary out-patient procedures on my husband. So when I needed to see a gastroenterologist, I did not hesitate to see him. Dr Raijman is always pleasant and quick to smile; he tells it like it using layman’s terms. It is my opinion that Dr Raijman is competent, confident and compassionate. These qualities have given my husband and me peace of mine and trust. He is everything I look for in a doctor. I highly recommend Dr Raijman as one of the best!"
