Our Story

Built on 35 years of hands-on experience

Owner Craig Denton has delivered five-star service to the St. Louis metro for over 35 years — first spending 15 years in the field, then owning and operating his own company for more than two decades.

After selling that business, customers kept seeking out his quality work and family-friendly approach. That loyalty is what led Craig and his wife Julie to establish Patriot as a small, family-owned business.

Today their son Shawn serves as Operations Manager and Logan as an apprentice, alongside a handpicked team built on a culture of caring and putting people first.

"Patriot guarantees to provide world-class service while maintaining the highest quality and workmanship from our dedicated technicians."
