Michael Petcosky – President & CEO:

Mike Petcosky is the President and CEO of the Petcosky Companies organization. Mike has been in business since 1980. Mike took his father’s business back in the early 1980s and officially incorporated Petcosky & Sons Plumbing and Heating in 1987. Mike then partnered with his brother Tom and grew the residential and commercial plumbing and heating company to an established successful business. Along the way, Mike also started a fire protection division which is now a separate corporation, Petcosky Fire Protection Inc. In March of 2020, the residential plumbing and heating service and install departments were acquired by another local establishment. This allowed for Mike to focus his efforts on the commercial markets.

Mike attended State University of New York at Delhi where he learned the plumbing and heating trades. Today, Mike holds multiple Plumbing and HVAC Licenses in over 10 + different municipalities. This allows Petcosky Companies to provide excellent service for their commercial customers' needs.

Mike has always developed his organizations to be family oriented. That’s why his kids are all involved in the business today. Mike constantly jokes that someday his grandkids will be the ones running the companies.

Mike enjoys spending his off time with family, whether it’s a family vacation, or weekend camping with his kids and his four grandchildren, Parker, Cameron, Skylar & Madison. Mike has also been involved in the fire service since 1978, volunteering with the Vestal Fire Department. His commitment to family and his community is what helps drives the success of his companies today.
