Your trust is our top concern.

We strive to keep the reviews trustworthy, honest & fair.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

My one office visit for a severe rash and itching condition was a Complete Waste of my time. I never had a doctor say "I'm Stumped" about a condition. He commented about having a several hundred national network of doctors he could consult to find a cause. Told me he would call me back, Never Did! I had to call back several times with no response or answer. He seemed to have no experience or qualifications in this medical field, only confusion and lack of professional courtesy to respond back.
