John Dettelbach, a man of wide-ranging interests and passions, as well as a rapier sharp wit, died on Oct. 9. He was 82.
Dettelbach spent most of his working life as a stockbroker, investment counselor and portfolio manager at various investment firms. He loved mentoring young brokers, helping clients with their estate planning and doing his own research.
In retirement, he counseled fledgling business entrepreneurs through S.C.O.R.E. He also briefly taught entrepreneurship at Ursuline College.
A lifelong Clevelander, Dettelbach attended Hawken School and Shaker Heights High School. At Shaker, he and his partner won the state doubles tennis championship. In the early 1980’s, Dettelbach left the brokerage business to build and help run three tennis and racquetball clubs: River Oaks, River View and River Run. After selling the clubs in the 1990’s, he returned to the investment business. He played tennis until he was 80.
Following graduation from Cornell University with a degree in mechanical engineering, Dettelbach served in the U.S. Army Reserves. He earned a law degree from John Marshall College of Law and, at age 50, an MBA from Cleveland State University.
He loved travel and planned all the family trips. Dettelbach served on the boards of The Temple-Tifereth Israel and Cleveland Racquet Club.
Dettelbach is survived by his wife of 59 years, Cynthia (former editor of the Cleveland Jewish News); children, Mark (Andrea), Kim (Steven Sachs) and Anne (Rick Kellogg); grandchildren, Alexa and Adam Dettelbach, Joshua, Hannah and Maya Sachs and Henry and Elli Kellogg; and siblings, Kenneth Dettelbach and Betsy Dettelbach Jenkins.
Donations in his memory may be made to The Temple-Tifereth Israel or to Ensemble Theatre, P.O. Box 181309, Cleveland Heights, OH 44118.
