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.

Perfect fit
At our initial visit, Dr. Harnois knew my entire history. I felt her caring and direct approach works well for me. Not only did she take the time to answer all my questions, but those of my friend who accompanied me. The follow up appointments have been just as good.Her staff is just as professional.

Conscientious and Caring
I have been seeing Dr. Harnois for 4 years. I feel she carefully listens, works to find alternatives solutions to problems not addressed by standard treatments, and is excellent when answering my specific questions. She is punctual, friendly, caring, and always up to date on current options for my condition. Highly recommend her to anyone needing specialized, expert, hepatology healthcare. I find all the staff at Mayo, from the registration to labs and offices to be courteous, caring, and conscientious. There is a reason Mayo Clinic is the top healthcare provider in Florida: the people they hire, train, and retain are competent, caring, and all about the patient. I never feel like just another client there.
