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. Tsai is a good Dr. but the staff is a mess. They call to confirm your appointment much to early and confuse my elderly mother and my self. I have asked them to call me instead of her as she has dementia and they WILL NOT do it and I am throughly frustrated! To top it all off the young man that works behind the desk is so soft spoken and has such a heavy accent you can barely hear him much less understand him.

I received quick, definitive diagnostic care from Dr. Tsai and his staff. I was referred to him, by my Internist, with a unexpected EKG reading. Dr. Tsai took a full history, did a thorough interview, and performed another EKG and a Echo Cardio. All within a 2 hour window. I got a copy of the report the very next morning, clearing me for my impending surgery.
