What Our Patients Say About Us

Dr. Andrade took care of my situation seamlessly, he was very knowledgeable about my condition and offered insight on what to do about my condition. His colonoscopy practice was pain-free and I didn't have issues after the procedure. His staff is very friendly and will take good care of you.

Dr Bellows is very patient and knowledgeable. He will patiently listen to your problems unlike other doctors that are just rushing through the 3 minutes they came see you in the exam room. He will explain the procedure without being judge mental. 100000/10 bedside manners.

I strongly recommend Dr Osias. Very professional and caring, and takes time to answer questions. His nurse Lisa is very helpful too in explaining procedures and cautions related to the treatment.

Great practice. Staff at check in helpful and kind. Dr. Rho was very compassionate to some concerns I have about tests needed. He spent as much time as I needed to understand my condition. Check out was efficient and everyone was compassionate and helpful. I am in healthcare and I hope my clients feel as cared for as I did during my visit. I also witnessed staff assisting elderly patient with directions for upcoming appointment.

His skill as a endoscopist is exceptional. I would highly recommend Dr. R. Meirowitz for all your GI related issues.

Dr. Andrade and his staff made my visit a stress-free experience. He spoke with me before and after the procedure and answered all my questions in a clear and caring manner. They are an experienced and organized team who made me feel very comfortable and I would highly recommend him to anyone looking for a GI doctor.

Dr. Bellows listened patiently while I explained my entire medical history and he took the time to address all of my questions and concerns before creating a plan of treatment for me. I was very concerned that I would be pushed into taking PPI's or some other medication for my GI issues, but Dr. Bellows did not pressure me in that direction.

I was seen right away. Dr. Shriver was able to quickly diagnose my issue with the minimum of discomfort possible, and recommend treatment. I am very happy with her manner, the manner of the nurse assisting her, and my overall experience.

Dr. Osias and staff (at both his office and the surgical center--Carol, Maureen, Dr. Hirsh to name a few) are professional, friendly, and made me feel very at ease. Was recommended to Dr. Osias by someone in my office and have already recommended him to someone else in my office.

Dr. Aloysius Rho is the best of the best. He is extremely knowledgeable and caring. He took his valuable time to explain the details when I didn’t understand. After the exam and tests, he even called to inform me the next steps I should follow. He wanted to make sure I was okay. It's so rare to find a doctor that is brilliant, highly skilled and dedicated. I would give him 10 stars if I could. Dr. Rho is a true professional and I would recommend him to anyone. The staff in his office is also very friendly and helpful.
