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.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

Dr. Larsh really takes the time to understand what's going on with your health, and recommend supplements, diagnostic tests and other non-invasive remedies . I particularly appreciate that she lets me contact her outside of an appointment times with quick questions so that I can continue on my Healing Journey.

She was a patient, loving, thorough, and straight shooting, one stop shop for our family's detailed health needs. She solved a problem my wife had which 13 other doctors were not able to solve. And we always enjoyed the visits. What more could we ask for?
