Joseph Anthony Helfrich Jr., 80, of West Chester, an orthodontist who operated offices in Broomall and Media for many years, died Saturday, Jan. 26, of cancer at his home.
In addition to operating his offices, he founded Oasis, a drug and alcohol awareness organization that focused on children in Delaware County, in the late 1970s.
"A patient died in a car accident, and he began speaking in schools about drug and alcohol awareness," said his son, Joe Helfrich 3d.
Dr. Helfrich was born Sept. 17, 1932, in Midland, Pa., son of Joseph Helfrich, a physician, and Regina Helfrich.
He earned a bachelor of science degree at the University of Notre Dame in 1950. He later graduated from the University of Pittsburgh School of Dental Medicine.
