    Dr.Johnson treats both my 8yr old daughter and I. We have had a positive, friendly, and comfortable experience so far. We see her for my daughters vitiligo and phototherapy weekly. She has been understanding, helpful, and flexible. She is quick to the point and thorough in my appts which I appreciate as a busy working mom of 4 kids with a laundry list of medical issues.
