I see because the Retina Group has managed my eye-care for nearly three decades. For the last several years Dr. Johnon has maintained the high standard that my vision requires. I have absolute confidence in Dr Johnson and the staff at the Retina Group.

After moving here from another state my experience with Doctor Johnson has been most satisfying. After three and a half years of being treated by my other doctor in my previous state I am more than pleased with Dr. Johnson who makes me feel very well cared for. I feel very lucky that he. Is my doctor.

Dr. Johnson is very thorough!!! Answered all my questions completely!!! I will return to see him in 6 months. I trust Dr. Johnson!!!

Dr. Johnson was recommended to me by Dr. Geoffrey Kaplan who recently retired. It was, as expected, an excellent recommendation. Dr. Johnson was thorough and had a very pleasant personality. I was very pleased with my first visit with him and look forward to having him as my ophthalmologist for many years. I, of course, will miss seeing Dr. Kaplan. He saved me from losing the vision in my left eye back in 2008. He was an outstanding ophthalmologist and I will always remember him with gratitude.

Mark is by far the best of Doctors He knows what he’s looking for and if he has found it or not, and the consequences. He tells you strait and what your alternatives are. I appreciate that very much

He is effective, friendly and answers all questions.

Oct 20, 2022
The Staff is always polite and efficient I love Dr Johnson's bedside manner, he never fails to ask how I've been since he last saw me and even checks on any travel plans I have for the future. However, he is a great physician, very knowledgeable and is very careful in explaining my condition each visit. I pray he is not priming for retirement, as I have lost 4 physicians to retirement this year.. Kudos to the practice!!!

Dr Johnson has been the primary guardian of my vision for decade. My eyes have fragile for at least 40 years and the Retina Group of Washington kept me okay through several crises. Dr. Johnson always is on top of my issues when h sees me
