John began his plumbing career in January 1984 as a plumbing apprentice working in Patchogue, NY. He worked for Erhardt Plumbing & Heating for five years at which time he was eligible to take the master plumber’s exam. Shortly after receiving a Suffolk County, NY Master Plumbers license in June of 1989, he moved to Vermont where he tested for his VT Master Plumber’s license. His plumbing journey continued through June of 1994 while working in VT for Northern Comfort Plumbing & Heating. In June of 1994, John decided to open his own plumbing and heating business that he successfully ran until June of 2012. John then applied for and was chosen for a State Plumbing Inspector’s position with the VT Division of Fire Safety. 

John worked full time with the Division as a plumbing inspector until December 2023, when he was promoted to Chief Plumbing Inspector. John enjoys working as a plumbing inspector; his favorite part of the job is interacting with plumbers, helping them understand the plumbing code and providing suggestions to assist plumbers on the job site. 

In addition to his day job, John teaches fourth-year plumbing apprenticeship classes for Vermont State College and conducts plumbers’ continuing education seminars through the Vermont Licensed Plumbers Association. John likes to incorporate his work experience and life lessons into class time instruction to apply a real-world perspective to some of the subjects he teaches. 

In his spare time, John enjoys fishing, hiking, cycling, camping, and working around the house and property.
