Our Journey: How Sepco Services Inc Became a Leader in Mechanical Contracting Services

Humble Beginnings: The Foundation

In 1993, John Seppy took the first steps in what would become a long and successful management career at McDonald’s. Over a decade, he not only gained invaluable experience but also developed expertise in creating efficient training programs and operational systems. This skill set paved the way for John's transition into managing service departments, focusing on HVAC and appliance repairs.

Commercial Mechanics Skill Transition

After leaving McDonald's, John invested the next eight years in the commercial mechanical and appliance industry. Here, he fine-tuned his technical skills and integrated them with cutting-edge organizational processes, which are now integral to Sepco Services Inc.'s (SSI) operations today.

Sepco Services Inc: A Family Start

In 2006, John, along with his wife Lisa and son Thomas, relocated to Deltona, FL from New Hampshire. Marking a new chapter, they launched Jolito Inc., a name ingeniously crafted from the initial letters of John, Lisa, and Tom. Initially known as Sepco Air, the company evolved into Sepco Services, eventually rebranding as SSI (Sepco Services Inc).
