Dr. Maria Johnson is such a great doctor. She listens to my concerns and I trust her judgment in every way. I trust her and I know I'm in good hands. I would recommend her to anyone.

I was referred to Dr. Johnson by my surgeon because I was having GI issues. Dr. Johnson is skilled at helping women and she is professional and empathetic in doing so.

What a pleasure to meet a new doctor that actually reviewed the information that you filled out prior to your visit in addition to looking at your medical record. She came prepared with a summary of what she found and then asked pertinent questions. Listened to my concerns and started working on a plan. Also, she is very nice, friendly. Office is modern and clean. Would definitely recommend.
