About Isaac Raijman, M.D.

Why did you choose to specialize in Gastroenterology?

I was most attracted to Gastroenterology for two main reasons: one to take care of healthy and sick patients and two the combination of endoscopy to allow a very different perspective in the approach to both health and disease. I was also attracted by the large variety the gastrointestinal tract offers. That is, the multitude of organs that can be studied. Gastroenterology also offers the opportunity of immediate healing, chronic management of disease or health maintenance and the possibility of helping through nutrition and not only pharmacology.

Do you have a specialty of interest within GI?

My approach is patient-centered, with application of best-practice medicine integrated with knowledge and skills acquired over many years of clinical practice.  I offer less invasive treatments through the most advanced endoscopic and medical interventions.  My goal is to provide compassionate care, comprehensive diagnosis and management within an atmosphere of comfort and trust for my patients.
I specialize in: Upper Endoscopy & Colonoscopy, Endoscopic removal of large and complicated polyps, ERCP: Endoscopic Retrograde Cholangiopancreatography, Cholangioscopy (Spyglass), Pancreatoscopy (Spyglass), Endoscopic management of complex gastrointestinal disorders, Endoscopic management of complex pancreatobiliary disorders, EUS: Endoscopic Ultrasound, Endoscopic management of Obesity, Endoscopic management of bariatric complications, Endoscopic management of Gastroesophageal Reflux Disease (GERD), Endoscopic management of cancer complications, Endoscopic management of Barrett’s esophagus, and Endoscopic management of Zenker’s diverticulum.

Dr Raijman is kind, through, cares and is an exceptional Doctor. Prior to going to Dr Raijman I had been to 3 other GI doctors who made things worse. I ended up in the hospital for several days with the other 3 doctors. Let me also say that this was 3 different occasions spanning 5 years and all out patient procedures. Dr Raijman listened. He is so skilled. I once the procedure was completed there were no complications and I was able to go home the same day. I highly recommend him.

I have known about this physician since moving to Houston from Beaumont. I have referred many patients, co-workers and even my mother to Dr. Raijman and now it seems I will be needing his expert care after a bout of cholecystitis. See you soon, Doc!

This Dr is great. I have a lot of stomach problems after a botched up gastric by-pass. He’s very smart and cares about his patients.I wouldn’t go to anyone else! His assistant Yolanda is great as well. Together they make an unbeatable team. I thank God I found them.And he’s pretty easy on the eye as well ; that helps a little when you're feeling lousy!.....😂😂Sorry doc I had to say what everybody thinks!😂 I’m an old lady so don't be afraid of me. On a more serious note thanks to the both of you for all the hard work you do..... To the whole team my heartfelt thanks.❤️
