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.

Dr. Miller has been wonderful. He helped me Identify and understand all of the different problems with my toes and feet. I now have a very simple over-the-counter treatment options that really work for my situation. It’s wonderful to be on a 10 week program to make sure my nails are trimmed correctly as I am prediabetic. I highly recommend you see Dr. Miller and have a wonderful treatment experience as I do. Cutting your nails, when you have neuropathy is a little scary better to be done by a professional!

Dr. Miller saved my life. I was so fortunate to have him as my doctor during my stay at OC Global for a heart attack. His kind demeanor lets you know he cares and will do what it takes to provide the best treatment. He is knowledgeable and always answers all my questions and takes his time, never rushing off. He is an amazing doctor.

I am a heart bypass recipient from 1979. My cardiologist back then was Mark Miller. My primary surgeon was Mohan Roy. I subsequently had angioplasty in 1988 to clear a clot on one cardiac artery. Other than that, I have had no incidents related to my heart or the bypasses accomplished in 1979. This success began with Dr. Miller's care and if we hadn't relocated to the Seattle area I would still be under Dr. Miller's care. I am forever thankful for, and indebted to, Dr. Miller.
