While attending the US Merchant Marine Academy at Kings Point, NY, Troy met Cecile Mae Owen. The two began their marriage of 50 years at the Academy chapel on November 24, 1949. They moved to Columbus, Ohio where Troy graduated from The Ohio State University College of Optometry. Troy practiced optometry in San Francisco, Loveland, Colorado, Corpus Christi and Houston and then began an academic career at the University of Houston College of Optometry. He had a passion for teaching and was known for setting a high bar for his students. He earned an award for teaching excellence in 1982, and co-authored a widely used textbook on the subject of clinical optics. Troy retired from The University of Houston in 1990 and was awarded the title Professor Emeritus. Troy was active in the First Unitarian Church of Houston and, during his 23 years in Kerrville, attended the UU Church of the Hill Country. Troy had broad interests and was always up for a lively conversation or debate. He enjoyed reading, woodworking, traveling and especially camping. Visiting with family and friends, reminiscing and telling stories gave him great joy in later years.

Troy is survived by his daughter, Heather Cassidy and husband Neil of Hunt; grandsons, Owen Cassidy and Rory Cassidy; great-grandson, Neil Cassidy; numerous nieces and nephews; and his cherished companion of many years, Julia Bill Davis.
