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.

He is a wonderful doctor. I would recommend anyone who needs a urologist to go to him.

Dr. McMahon was very thorough, professional, and efficient. He explained the procedure step by step during my surgery. His nurse, Eliza, was excellent as well.

I highly recommend Dr McMahon
Dr McMahon is wonderful, very knowledgeable and personable. I saw him for a surgical followup. Although I disagreed with his decision to hold off on removing the nephrostomy tube I have in, he explained what went on during my surgery and the reasoning behind keeping it in til it can be done safely. In his words, he just wanted to cross all his t's and dot all his i's so I heal properly.
