I have had great care and would recommend Dr. Johnston. I haven't had problems with the office staff, but have only been for regular care.

This was an awful experience. I would not recommend and the office staff and assistant are very unorganized and do NOT return your calls or answer your questions on time!

I was a patitent of Dr. Johnstons for about 10 years in Tucson. He was a very good doctor, very friendly, very knowledgible. Very good not pushing medication that isn't needed, and very good at getting you off medication that you shouldn't take forever. Asked a lot of questions when you had a problem.

I've been very happy with Dr. Johnston - very sad he's moving out of state.
