John started working at Quality Pool Supply in 1979. He was hired to open the first branch, which was to be located in western Michigan. John is married to Marsha Engelhart Coulier (which may explain why he was hired!). He is now the Vice President of Sales/Marketing.

John’s business strategy is very simple — Quality Pool must provide superior service and products to the pool and spa professional if we are to prosper.

John and Marsha have 3 children — Chris, Michelle and Laura.
