Dr. Mareth is a great person. He's extremely thorough and explains everything to you, went over my past visit entirely, reports from all of my tests/procedures from all of my other doctors. Never ever rushes me out, asks if I have any questions or concerns. Dr. Mareth is very knowledgeable. I would recommend him to anyone.

Dr. Mareth takes the time to look at your individual situation based on your health and your age doesn’t require things to be done just to run up a bill. I trusted his decisions and feel very comfortable with him..
