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.
Dr. Sui is all around wonderful doctor---professional, listened and answered all my questions/concerns. Excellent doctor.
I would so recommend anyone I know to go to Dr. Sui.

Post a ResponseAre you Dr. Siu?
I was told to see Dr Siu after going to the Morristown ER with intense stomach pain every time I ate. My ER doctor had talked with his colleague, who assured him I could be seen the next day. When I called, Dr Siu denied that phone call ever took place, and then absolutely refused to see me. He tried to push me off on a NP. Absolutely horrible treatment for someone who was told by the practice that I could be seen. Would not recommend.

Dr. Siu did a minimal invasive procedure of ERCP to me to remove the gallstone which blocked the Common Bile Duct and cause the inflammation. The procedure was performed very successfully. I have no pain and the recovery was so quick. I will definitely recommend Dr. Siu to my family & friend.

I love love love him! He cares for my very complex disabled sister. We’ve had no problems, delays or wait times at all. He’s easy to communicate with, explains everything to both of us, respects and never talks down to her and has the best support staff. He’ll be my new GI when I need my next colonoscopy.
