Dr. Phillip DeMott

Dr. Phillip DeMott joined our practice in 2020. After completing his bachelor's degree in Biological Sciences at the University of Delaware, Dr. DeMott attended Nova Southeastern University College of Optometry in Fort Lauderdale, Florida. Upon completing a second bachelor's degree in Vision Science and Doctor of Optometry Degree, Dr. DeMott returned home to serve the community in which he grew up.

His efforts will honor the work that both Dr. Betts and Dr. Biddle brought to life.
