Dr. Derrick Thornborrow O.D.

Dr. Thornborrow is officially retired as of July 2020. Here is a farewell message from the founder of our clinic:
“After more than 40 years of practice I have decided to retire. It is with mixed emotions that I made this decision. Although I look forward to spending more time with family and friends, I will dearly miss all the patients that I had the opportunity to know and care for over the last four decades. I have no doubt that I am leaving your care in the best of hands. Dr Derrick Thornborrow”
