John L. Benish 'Jack' founded HYDRONIC SUPPLY in 1958. 

Formerly with the American Standard Company on Dexter Avenue in Detroit, Jack initially operated Hydronic Supply out of a small warehouse in Berkley, Michigan.  In 1964 he moved the growing company to larger quarters in Troy, MI.

In 1991 Jack sold the company. His forward-thinking vision, his attention to service, and his quest for industry excellence, however, remain the driving forces behind HYDRONIC SUPPLY.
