In 2001, Paul and Josie welcomed their son-in-law Jeff Cassidy into the company. Jeff took over management in 2011 and, along with his wife Jamie, eventually became the new owners when Paul and Josie retired. Today, the tradition continues with their son Luke Cassidy joining the business—marking the third generation of family leadership.

Jeff has built a strong reputation as one of the region’s most skilled and trusted service contractors in the plumbing and heating industry. Now, he’s proudly passing on his knowledge and experience to the next generation, continuing the legacy of quality service and customer care.

With more than 40 years of excellence as a foundation, Jeff and Jamie are committed to carrying McGuire Plumbing and Heating into the future, guided by the same honest values and dedication to service that started it all. Whether it’s a simple repair or a full system installation, our family is here to help yours—with integrity, reliability, and pride in every job.
