I called the office and said I had floaters and flashes. They had me come right in. Dr. Johnson examined me, found a small tear, and immediately did a laser weld procedure. I was pleasantly shocked that eveything went so quickly and successfully. He has me on a much appreciated followup schedule.

Dr. Mark Johnson and his staff was very friendly. I checked in and was taken for my appointment within 5 minutes. Will recommend him to my friends.

Sep 25, 2019
He told me the truth about mt eye which several other doctors had no idea what was going on in my eye. Dr. Johnson has been my doctor for several years.

Sep 25, 2019
A change in my vision led me to ask for an unscheduled office visit which Dr Johnson was willing to accept,. Hopefully, the new drops he prescribed will solve my problem. Can't ask for more than that. He's GREAT...

Sep 25, 2019
Dr. Johnson is very personable in addition to being extremely forthright, understandable and professional. I trust him and his judgement totally.

Dr. Johnson is very thorough and professional. His approach is personable and he takes the time to answer any questions I have. He also offers comments that increase my understanding of the health of my eyes. The RGW group is very efficient and a pleasure to work with.

Sep 18, 2019
Dr. Johnson is clearly highly trained but very approachable. He explains issues related to vision in very understandable terms for a non clinician and thereby nurtures trusting and, at least in my case, long-lasting relationships with his patients.

Sep 18, 2019
Very knowledgeable doctor. Clean office. Everyone was nice.

Sep 18, 2019
Professional, personable

This is a busy office. Once you have tests, eye pressure, etc., then dilation, it would be great if they put YOU in one place and moved the techs. The waiting area in the center functions, but I closed my eyes between technicians. For routine exam, I got there early, it took one hour. Dr. Johnson interested and quite pleasant.

Sep 18, 2019
The appointment was a good experience. I was seen on time; the techs were very respectful and helpful

Sep 18, 2019
Explains your eye condition well. Personable, knowledgeable. Respects your time.

Sep 17, 2019
Dr. Johnson makes you feel relaxed and secure as he diagnoses and treats you. I have complete confidence in him.

Sep 17, 2019
Very knowledgeable! Took the time to listen, answer my questions, and ensure I understood what was going on with my sight before releasing me. Great experience!!

Sep 17, 2019
Good but took a really long time for bluryness to clear up I didn't leave your parking lot for nearly two hours andmy eyesight is still blury at 6 pm.

Sep 17, 2019
Great guy!

Sep 17, 2019
Since my problem is not an emergency I like what Dr Johnson is doing by starting with the least invasive procedure. I was also very glad he was able to do the next procedure at my appointment today instead of having to come back.

Sep 16, 2019
He is an amazing doctor

Every one was very nice and knowledgeable
