About Brian McGuire


As CEO of Geissler Roofing Co, Inc., Brian McGuire brings decades of hands-on experience, leadership, and dedication to every project. With a professional journey rooted in craftsmanship and community, Brian has become a respected figure in both the roofing industry and his local community. His deep understanding of the trade—paired with an unwavering commitment to quality—has helped maintain Geissler Roofing’s legacy as one of the most trusted roofing companies in Illinois.

From Carpenter to CEO

Brian’s career began in the St. Louis Metro area, where he worked as a Union Carpenter for 17 years. It was there that he honed his technical expertise, learned the value of precision, and developed a strong work ethic that still defines his leadership today. In 2013, Brian joined Geissler Roofing Co, Inc., quickly proving himself as a skilled Project Manager. For a decade, he managed complex commercial and residential roofing and remodeling projects, always prioritizing craftsmanship, safety, and communication.


In 2020, after years of dedicated service and proven leadership, Brian transitioned into his current role as CEO. Under his direction, Geissler Roofing continues to build upon its 95-year history of excellence, blending traditional trade skills with modern technology and customer-first service.

Leading with Experience and Integrity

As CEO, Brian oversees both the commercial and residential divisions of the company. His background as a tradesman gives him a unique advantage—he understands every phase of a roofing project, from hands-on installation to the logistical and managerial challenges that come with large-scale jobs. His leadership emphasizes teamwork, safety, and a relentless focus on delivering superior results for clients across Illinois.


Under Brian’s guidance, Geissler Roofing has continued to earn recognition for its commitment to quality and professionalism. With certifications from top industry manufacturers such as CertainTeed, GAF, Versico, and Johns Manville, and affiliations with respected organizations like NRCA and SIBA, the company has built a reputation for reliability and excellence. Whether it’s a commercial repair or a residential remodel, Brian and his team approach every project with the same dedication to doing things right the first time.

Service Beyond the Job Site

Outside of his professional career, Brian’s life reflects his dedication to service and community. For 27 years, he served as a volunteer firefighter—an experience that shaped his leadership style and commitment to helping others. Even after retiring from firefighting in 2023, his desire to give back continues through his role as a Trustee on the Board for the Village of Swansea. His service-oriented mindset extends into every aspect of his work at Geissler Roofing, where safety, reliability, and care for clients remain top priorities.

Family, Hobbies, and Personal Passions

When he’s not managing projects or leading his team, Brian enjoys spending time with his wife, Stephanie, and their children, Maggie and Owen. His favorite moments include watching Maggie play soccer and relaxing with Owen while watching Marvel movies. Away from home, you might find him at the racetrack—his lifelong passion for stock car racing reflects his love of speed, mechanics, and competition.


Brian’s hobbies also highlight his well-rounded nature—he values hard work, but he also appreciates the importance of balance, family, and fun. Whether it’s cheering at a soccer game, spending time in the garage, or supporting his local community, Brian brings the same level of enthusiasm and care that he applies to his professional life.

Education and Training

Brian’s professional foundation began through the Carpenters Apprenticeship Program, where he developed the technical skills and trade knowledge that would shape his career. Those early experiences not only taught him craftsmanship but also instilled a deep respect for the trades and for those who dedicate their lives to mastering them. His continued commitment to professional growth and education remains central to how he leads Geissler Roofing’s team of certified union tradesmen.
