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.

Knowledgeable and Caring
Dr. Hsia helps me to handle my complicated gastro problems. In a thoughtful and caring way, he works with me to find better ways to live with the challenges. I am a 73 female with other health problems also. Here's a related detail you might appreciate: He uses the best technology to do a colonoscopy. And he does the procedure with finesse so it's not unpleasant.

Avoid this doctor! He did not give me my diagnosis at a follow up appointment for an endoscopy. He said he couldn't find anything wrong and was sorry. A week later I found out I had a stomach infection. I went to my pharmacy to pick up a different prescription for someone else and found out I had medication waiting for me prescribed by Dr. Hsia. I've been waiting for a call back from him because I have questions and concerns. Horrible doctor, I do not recommend him!!

My experience with Dr. Hsia was beyond excellence. He saved my life when i was at Marian Hospital after Gallbladder surgery. He was called in because the bile duck had ruptured and he went in through the mouth to insert a stint and saved my life. I can't say enough. He is so dedicated to his patients. He treats you like family. I trust him so much!!

Have been to his office for about 3 appointments and always have a long wait to see the doctor. My most recent appointment I waiting 1 1/2 hours past my appointment time before they called me back to the room and then another 30 minutes in the room waiting for the doctor. Dr Hsai is very kind but honesty I worry about him. Each appointment he has told me conflicting advice and doesn't seem very confident. He seems obsessed with juicing and supplements to "de-tox" the mercury from my body.
