Dr. Fareau is a compassionate health care provider who listens, cares and helps develop a plan that serves me the best way possible. I have seen other endocrinologists and my health care was not served well. From the first appointment until now, 4 years later, my health is so much better because of the plan of care. I am so happy with my current status and the wonderful, compassionate care of Dr. Fareau.

I had a different provider when I found out about my condition. I went to see him because I was feeling out of sorts a couple of months later. He didn't listen to what I had to say. He said my numbers were fine and so was I. I haven't seen another doctor for 10 years until now about. I am very happy with my new provider. He answered all my questions. I was very comfortable with him. I will keep Dr. Fareau as my new endocrinologist.
