See what our patients have to say about GANJ:

I saw Dr. Abraham and had a wonderful experience.

She fit me in as an emergency patient the same day I called. She is very kind and calming. I would recommend this practice highly.

So glad he is my doctor...

Changed my hospital and was referred to Dr. Shami. He, as well as his staff are great, very patient and thorough. So glad he is my doctor and hope others experience same wonderful treatment as me!

Dr. Grossman was the best.

I was very sick. I had a gall stone in my liver. Dr. Grossman was the best. He knew how sick I was and explained everything he was going to do to me during my surgery. He is the best.

Patricia Lynne Castro

A wonderful, friendly, highly skilled doctor

I have recently had a procedure done by Dr. Grossman.  I can recommend him without hesitation.  I was having difficulty and called him at 5AM, (woke him) he was not upset that I called.  He told me to call any time without hesitating.  When I had my initial appointment with Dr. Grossman in his office he gave me his cell phone number and told me to call him with any questions. (That is how I was able to reach him at 5AM)  After the procedure he met with my wife and myself and spent quite some time explaining what he did and the outcome of the tests. He is a wonderful friendly highly skilled doctor who i would not hesitate to recommend.

I came here to Dr. Roth from Tennessee

because I trust his expertise and his interest in my well being.

-Ronald Gierek

We like Dr. Roth for professionalism and care.

I met Dr. Roth when I had an emergency through my brother Dr. Ciocon. Made Dr Roth as primary doctor together with my wife Delia.

I have been a loyal patient of Dr. Zierer's for many years.

Not only has his level of care been of the highest caliber, his office staff have always been very helpful and accommodating. I do not hesitate to refer Dr. Zierer and his team whenever a colleague/relative/friend is in need of a quality gastroenterologist.

I've been a patient since 2009

with GI issues. Dr. Z ad his staff are excellent.

I've been seeing Dr. Ruiz for about 15 years.

When I first came I was in quite a bit of stomach pain. He immediately scheduled a endoscopy for the next day. I was amazed and happy as usually there is quite a wait. Through the years he's had to change my meds. If i have any issues he is always willing to solve them along with the staff. I can say going through an endoscopy or colonoscopy is not fun but each time he has made me laugh.


I would highly recommend this establishment.

I was having pains in my stomach and everywhere else so I looked into a gastroenterologist. To my surprise, I was welcomed with open arms by Dr. Patel's staff. After having a few procedures done, I would highly recommend this establishment to anyone. Dr. Patel is by far one of the kindest, most honest and caring doctors I've met in my lifetime.
