John Slattery

John is the co-owner of AGS HVAC Services and a crucial member of our team. After starting in the industry in 1987, he earned his mechanical contractor license, which is currently active in Massachusetts, Rhode Island, Connecticut, and New Hampshire. John also spent four years in the Navy as a Second Class Engineman. He and his colleague Michael Gamache Sr. started AGS in 2014, capitalizing on the customer service approach they wished they’d experienced in past roles.

Today John is the proud father of two, college graduate girls, Tybal and Myriam. John usually spends his free time overseeing his family farm.
