Born and raised in Delaware, OH, I am the youngest of two siblings; Melissa DiNovo and Michael DiNovo III. I attended elementary and middle school at St. Mary vocational school and went on to be a fighting Baron at Buckeye Valley High School.

It was in my later years of high school that I realized my dream to become an Optometrist and I even wrote my senior term paper on the subject. Upon graduation I enrolled at Bowling Green State University where I obtained a Bachelors in Science in Biology and a minor in chemistry while I was securing my Optometry pre-requisites.

 I was then accepted into The Ohio State University College of Optometry. Four years and several Buckeye football games later, I accomplished my Doctorate in Optometry and began working at several Columbus Optical chains. However, it did not take long for the dream of working in private practice to resurface, I quickly realized that it was time to make the final step to reach my goal and return to my hometown, Delaware, to achieve it.

The Delaware community, with my family and friends, has always supported and encouraged me. Now I want to share my education and dream by providing thorough, honest, on-going eye care to the community that has always been my home. I specialize in Pediatric Optometry and Vision Therapy.
