Our History

The roots of The Koetting Associates can be traced back over 100 years when John Koetting opened an optical shop along side his jewelry store. His son, Dr. Felix Koetting, began his optometric practice in 1921, followed by his son, Dr. Robert A. Koetting, who founded The Koetting Associates. Today, our professional staff is led by Dr. Carmen F. Castellano, a nationally recognized contact lens specialist, who is one of only 200 persons to have successfully completed the requirements to become a Diplomate in the Section on Cornea, Contact Lenses and Refractive Technologies of the prestigious American Academy of Optometry. Dr. Castellano was joined in practice by his sons, Dr. Joseph Castellano in 2011, and Dr. Nicholas Castellano in 2016. Our doctors work with a team of trained assistants and technicians.
