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.

What all doctors should be
Dr. Hasler successfully diagnosed me with celiac disease long after many doctors would have sent me on my way with an IBS diagnosis. Thanks to him I was able to confidently adopt a gluten free diet and I got my health back. Years later, I still think about how lucky I was to get a doctor that was so knowledgeable about the space and willing to do the work to identify the problem. Throughout, he took the time to hear everything I had to say and explained all of the tests he was having done. My first appointment, one of the nurses warned me "Dr. Hasler is running way behind, so you'll be waiting a while, but it's because he's the best doctor here and he takes to time to talk to all of his patients", so I just made myself comfortable with a book. It was worth it. Dr. Hasler, I hope you read this someday so you know how grateful I am for you.

Dr Hasler helped me when I felt I had no other choices in my healthcare. He always answers all my questions and has helped me learn and understand my health conditions. He diagnosed me with a few things when no other doctors had a clue of what was wrong with me.
