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. The best of the best. Extremely professional
Very friendly. Receptive. Didactic. Very professional.

Dr. Cusnir instilled in me total confidence. I never read the reports in my online account because i didnt know what i was reading or how to interpret the results. Each time I saw him he told me my blood test and scans were excellent and dont read the internet. His manner was low key, always encoraging and I believe and trust in him totally.

Dr. Cusnir and his staff are one of the best in what they do. We couldn't be more grateful with them for everything they did for our father throughout his entire journey. Dr. Cusnir provided us comfort and hope in such difficult time for our family. Don't hesitate to contact them if you or your family needs medical help. Thank you from the bottom of our hearts, Shelly & Shirly Czaikowski

A family member was suffering from Cancer and Dr. Cusnir and his wonderful PA, Karen, saved her life!!!!!!!! I simply cannot recommend them enough as they caring, patient, professional and incredibly competent. To say that they performed a miracle would be a gross understatement! Thank you Karen and Dr. Cusnir as without you, life would have simply and quickly ended for my mother.

I am so grateful for Dr. Cusnir and his entire staff. After the horror and near death experience my mother endured at Baptist. Dr. Cusnir has been heaven sent. He has the illest people feeling upbeat and positive. It’s amazing how much sunshine he brings to the patients not to mention his experience and dedication to fight this horrible decease. I have seen so many cases here, and no matter how sick the person is they are actually truly happy to be in his care. I highly recommend him.

Lied to brother about extent of his condition so he and his NP could keep billing insurance for unnecessary and unhelpful procedures. Instead of dealing with a Stage IV Colorectal/Liver Cancer patient in a responsible and ethical manner, he manipulated him into believing he could be cured - and my brother died alienated from his family because of the lies this doctor told.

Dr. Cusnir saved my mother's life- she was diagnosed with breast cancer last year. His professionalism, solid staff and team, unending and uplifting optimism and honesty helped our family navigate and weather the emotional, medical and practical rollercoaster that a full treatment involves.

I'm writing this two years after my case of Hotchkins Lymphoma was successfully cured by Dr. Mike Cusnir. Make no mistake, this is a doctor of the highest order both in his adeptness in curing cancer and in his personal bedside manner. He is of such great substance and wisdom....a divine, gifted physician, one I will never forget.
