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.

Bad Doctor
I saw Dr. Yoshii for environmental allergies. When he wanted to do a skin test, I asked him if this test is safe while taking the medications I am on. He said yes. I did a quick search online and found that patients taking the blood pressure med I was on are prohibited from undergoing the skin test because you can have a life threatening allergic reaction that cannot be reversed. When I confronted about this, he had the deer in headlights reaction and was embarrassed that I caught his mistake. We agreed to do allergy blood testing instead. When I came back for the follow up appointment to go over it, he said that I should not have come and my primary care physician should go over the results. You could tell he was just upset that he couldn't do his expensive allergy test to make money.

I just saw Dr Yoshi today and was completely blown away at his amazing natural suggestions that he offered instead of pushing prescription drugs on me. I would highly recommend him as he is truly trying to solve your problems by getting to the heart of them rather than putting a bandaid on them.
