Richard attended Holy Cross Elementary School and Erasmus Hall High School, in Brooklyn, where he excelled at track.

After graduating from High School in 1964, Richard began working for JP Morgan Bank, until 1965 when the family moved to Bowie, Maryland. Upon arriving in Maryland, Richard enlisted in the Navy, in April of 1966. Richard was stationed at Norfolk, Va., aboard the guided missile destroyer, Richard E. Byrd, (DDG-23). Richard participated in numerous cruises to the Mediterranean Sea, and one cruise to the North Sea. His ship was one of the first to give assistance to the US Navy Ship, Liberty, when it was attacked by the Israeli Air Force, during the first Arab/Israeli War. Richard completed his active service in January of 1970.
