Love love Dr Kastuar! His officer staff is always pleasant and willing to help. Dr Kastuar stays on top of all the newest medical modes and I feel very confident with him.

I was so freaked out that my doctor sent me to a specialist but after seeing Dr. Botros I instantly felt so much better. He sensed I was nervous and took the time to talk to me. I could not have asked for a better doctor!

Dr. Yuri Volk is a doctor par excellence. Compassionate, caring, trusting, knowledgeable, and always goes the extra mile without asking. The best way to describe what I feel about the doctor is to say that I wish "all doctors were like Dr. Volk"

Dr. Pickover was thoughtful, kind, gently, thorough in exam and all explanations. He took his time to explain things to me and answered every question. I’d recommend him in a heartbeat.

I have been using Dr. Steven Krawet for many years. I find him understanding, compassionate and extremely professional. If you want a really wonderful physician I strongly recommend Dr. Krawet.

Dr Nahar was very friendly. She was able to explain the cause of my symptom and what to do to help my situation. All my questions were answered. I will be scheduling a follow up appointment in the near future.

Dr. Kastuar truly cares about the well-being of his patients. He has demonstrated quick availability to me as a patient and as a family member. He has always been thorough, professional, and kind to me and my family! I feel comfortable that he is exceptionally competent in his knowledge and treatment.

Dr Botros is very nice and informative! His staff is also friendly. I had procedures done by him 2 yrs in a row and everything went smooth! They were done right at his office with his professional staff. I highly recommend Dr. Botros.

Dr Volk is very knowledgeable, friendly, compassionate, and takes the time to answer any questions. In my experience he will always go an extra mile to help his patients and give them a comprehensive understanding of their conditions and outlook. I would recommend him to anyone I know.

Dr Pickover has been my families (mother, father, brother, husband and myself) doctor for over 25 years. He is kind and knowledgeable. I would recommend him highly to anyone that needs a gastro doctor.
