I was looking for the optometrist in London and came across Dr. Mao Clinic. I am very happy that Dr. Mao is my family optometrist. He is extremely knowledgeable, explains everything very well, and is very thorough with examinations. I have found Dr Mao and his staff, Marketa and Corrine, to be both very professional and pleasant. Corinne was a lot of fun to work with when choosing new glasses (which I love!). Her expertise is clearly evident and I fully trust her opinion. Thank you for your excellent care and I look forward to trusting Dr. Mao with my and my family vision and eye care needs for many years to come. You are the best!
