Ray graduated from Crandon High in 1954. He was a student of life and never stopped his quest for learning.

In addition, he set up the science department at the new Southwest High School, where he was the department head, taught AP chemistry, physics and ran their planetarium. He retired in 1994.

His other jobs included, being a nursing chemistry instructor at North Western Technical College, Brown County civil defense instructor, teaching radiological monitoring and being a chemistry instructor at University of Wisconsin Green Bay.

He also enjoyed reading many books from his extensive religious library, as well as devoutly attending daily Mass, both at home in Florida and while on vacation. His faith was very important to him and a Pilgrimage of the Marian Shrines in Europe on September 11th had a significant influence in their lives.
