"I chose to specialize in Gastroenterology because 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. 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. In my free time, I am an artistic painter, something I have done since my early teens. I like to exercise both indoors and outdoors, and I like to travel. In addition, I enjoy gardening, am an avid book reader and like everything about wines, from making to drinking."

"Dr Raijman has been my doctor for years, however when I had been given a diagnosis of a sliding hiatal hernia I knew I needed to reach out to Dr Raijman. We had a visit where he listened, asked questions and we came up with a plan. I trust him with my health and I have a background in the medical field and primary care giver of my parents. I have very high standards for a doctor and staff. Dr Raijman checks all the expectations I have for a doctor I can trust. I recommend him to anyone who wants a great doctor for their medical care. "

"Our first visit to Dr. Rajiman was great. He came in , sat down and started asking me questions about symptoms and how I was feeling. I felt so comfortable answering his questions . He seemed very familiar with what was going on with me and I felt like he knew exactly what I had before he walked in the door. He explained what he thought I had and what procedure he was going to do. I walked out feeling like he took the time to know me before he came in, was caring, informative, and I was very grateful I had found him to treat me."

"Great doctor, always methodical and logical with amazing experience and expertise which matters the most. In addition, his staff, especially Yolanda always helpful, considerate, prompt and super nice makes our visits pleasant. We always feel hopeful and energized after every visit. My family and I will never go to another GI because we found the best there is."

" Dr. Raijman was informative with my health problems. I was impressed with him."
  • November 7, 2023
"I’ve been looking for answers for about 4 years through multiple GI’s. Decided to drive 2 1/2 hours to Dr Raijman. After a full explanation of symptoms and history of pain, he quickly identified a diagnosis. Said it’s a common problem, but hardly diagnosed by GI’s. Solution is a simple med treatment. I am finally relieved to have a proper diagnosis and treatment plan. Only been suffering for 4 years with incompetent GI doctors. I feel like Dr Raijman is on the side of his patients well being, not on the pharmaceutical side or insurance side. Hard to find people and/or doctors like this. "
  • October 31, 2023
"Dr Raijman and his staff are the best in their profession. His knowledge of our situation before, and after the procedure gave us the confidence that we were in the right hands. My husband, Hallie, and I will continue to keep Dr Raijman as our provider for this type of professional service."
  • October 1, 2023

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.

We value your input and encourage you to reach out to our support team if you encounter any issues.
