Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

A Life Saver!
By the Grace of God, Dr. Raijman found me. I owe him everything, as he quite literally saved my life. He was the fourth doctor I saw, but the only one who offered a solution that was the least invasive yet the most effective.His expertise, confidence, and compassion gave me hope when I was losing it. He always takes the time to truly listen, answer my questions, and he makes me feel like a person, not just another case. Thanks to Dr. Raijman, I’m here today, healthy and healing. I will forever be grateful for his care and for the path that led me to him.

New patient
Dr. Raijman reviewed my history and imaging and made a recommendation for outpatient surgery, to remove stones from my pancreatic duct. I feel confident in his assessment and his abilities as a surgeon. Looking forward to getting this completed.

Awesome Provider
How kind he was with a smile. He explained what was going on with me. He went over my options and explained in detail how he could help my situation. I have been a patient since 2015 and although I now only have to see him once a year, he still greets me as though he just saw me the week before. I don't feel like a medical number, I actually feel like a respected, cared for patient.

Dr. Raijman first visit
My appointment was the first thing in the morning so was very fast with the paperwork. After a dialogue weight and blood pressure with the nurse, the Doctor appeared ask a bunch of questions, answered mines and was very transparent with the colonoscopy procedure. I felt he knows what he was doing with a lot of experience and put to rest all my fears. After we scheduled the procedure and we will see how it goes
