Della began working with Dr. Appelfeller after he had just graduated from dental school in the late 1970´s. She assisted him for one year in his office in Ashtabula Ohio. She then worked as a dental assistant for dentists in Ashtabula and Conneaut Ohio before joining forces with Dr. Appelfeller once again in 1990. Della is a self proclaimed "partially retired" person who just loves her job and the people she encounters at work too much to give it up all together. She helps out part time at the office preparing charts, keeping the hygiene schedule full and sending birthday cards to patients. She is very family oriented and enjoys spoiling her four grandchildren and two great grandchildren. Della also stays young by participating in outdoor sports like tennis.
