I have been a patient of Dr Mark Clement for almost 20 years. In that time, my family has grown from 1 to 6 people. My youngest is only 9yrs old now, but has been seen by Dr Mark since she was about 2yrs. Service and quality here are EXCEPTIONAL!! I have kept Dr Mark for my family's eye care needs even when I was living in Ohio and traveling over 100 miles to come in. The staff here is excellent, the doctors are fantastic, and the eyeware sold here is of great quality at a fair price. You will not find better eye care ANYWHERE in the Pittsburgh area!!
