I like Dr. Merz's mellow manner.

Lucky to have Dr. Merz.

The best cardiology practice.

A very knowledgeable & kind doctor.

I am very satisfied with my provider - No problems with my care providers.

Always very good.

Dr Merz is my cardiologist- a wonderful caring Dr that takes time to listen, explain & diagnose. I have never had to wait long in reception room nor waiting for exams to be conducted. I would definitely recommend Dr Merz. He was also my parents' cardiologist. Excellent Dr! Thank you
