Dr. Michael Mathier is one of the best doctors there is. He is the consummate professional, caring, and very thorough. I have complete trust and faith in his medical advice and abilities. Dr. Mathier's staff is also a reflection of his care for his patients. Nurses, techs, etc. are all the cream of the crop.

Dr. Mathier and his staff are why my heart health and blood pressure has been stable the past 16 years.

Dr Michael Mathier is a very knowledgeable and compassionate medical professional. He has been by my side for over 16 years providing medical treatment and coaching to successfully live a full life while surviving heart failure caused by chemo. His nurse Lisa is always available to respond to my questions. I feel Dr Mathier, his nurse and UPMC have my best interest in mind.

August 20, 2018

From scheduling to reception to check-up preliminaries with nurses/PA to actual visit with the doctor, the experience was first-rate. I have been going there for twenty years, first for treatments then for continued follow-up check-ups, and cannot remember a negative experience. they take care of me and do it professionally and respectfully.
