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.

The doctor was excellent, so was the staff
Dr Raijman is a seasoned and thoughtful gastroenterologist, with a keen clinical eye and sincere interest in the wellbeing of his patients. His approach to medicine is patient centered, and his staff has the skills to complement the Dr and treat you with respect and empathy. The office is busy, well organized and welcoming. Your time is respected. A great experience !
Very impressive all around. The doctor the office, the staff, very professional, and I felt very at ease and comfortable.
He was fast, effective, and professional in every way.
I tried to do a telehealth video with Dr Raijman, only because I live 2 hrs away. All I had was my phone, which his nurse said was fine. When he came on the video chat, he messaged me. Asked if I could hear him. I heard some noises but not his voice. So I answered yes I can. He asked if I was on a computer. To which I said No I’m on my phone. From the little I could see his face, he seemed aggravated. Then, my phone screen went dark. My phone then rang, and he was calling me. I guess the technology for the video app wasn’t working. He asked me what I needed. So I felt a bit like I was disturbing him. I said this is my 3 month follow up visit that you requested. He said ok how are things going? After only about 3 minutes of explanation, he said just need to increase your RX dose. Then, I assumed I was on hold. I was talking, but there was no response. After 8 minutes I hung up and called back. All I got was the answering service. The Doctor never tried to call me back. And, I had just paid $145 for this video call. So, I was a bit angry, but decided I’d call back in the morning. Thanks to his nurse who communicated with me and him, I finally was able to explain my problems, and she was able to get me some answers. I’m glad his staff are so good at patient communication and actually seem to care. Maybe it’s just that technology doesn’t work when you need it to. And maybe he hates technology much like I do. If he hadn’t offered to me to do telehealth because I live so far away, I would have found a way to get to his office. This is a perfect example of how technology can either send the wrong message, or not send it at all. I just know it cost me $145.
