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.

I am a type 1 diabetic of 62 years. I have seen Dr. Peck for about 15 years. She is the best endo I have ever seen. She is the most thorough, caring Dr. She goes the extra mile to give you the best care possible. I can't say enough about her!

Ignores Phone Calls
I'm diabetic and she has ignored multiple phone calls to get a refill for my diabetic testing supplies. Waited in her waiting room for over an hour to try and see her and she ignored that as well.

Despite having regular thyroid panel test results, I was sick for a long time. Dr. Peck helped my troubleshoot what might be wrong and helped me get better. She carefully monitored my endocrine function throughout my pregnancy and was kind enough to put up with messages at all hours that I sent in a panic, by responding to them promptly. I'm leaving California and I'm praying that the laws surrounding the location of a doctor or patient change so that I do not have to find a different provider. I've had the misfortune of seeing many doctors and Dr. Peck is one that I hold in the highest regard.

Dr. Peck has worked with me for the past five years and has tried many things to help me get my diabetes under control. Finally I am better. If I had done things she recommended sooner I would have been in better control sooner. Excellent practitioner.
