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.

I’ve been seeing Dr. G for several years after losing a kidney enclosed in a 13 pound tumor. He is very empathetic, very knowledgeable and professional in his plans for my wellbeing and keeping my other cancer ridden kidney as long as possible.

A Physician's Physician: Dr. Gajanayaka
"Dr. G" was thorough, explained in detail my health status and set me on a plan to preventively manage and ensure my quality of life for the rest of my life. He wasn't rushed, asked questions of me, answered my questions and I have the confidence that I have an outstanding member on my health team. The office staff were kind, friendly and demonstrated that they cared I was Dr. G's patient. I have never been the patient, but always the doctor. I had (and will have going forward) an outstanding patient experience!
