Dan Provencher has devoted nearly five decades to industrial steam and combustion systems, beginning as a U.S. Navy Boiler Technician and progressing through senior engineering roles in hospitals, power plants, and manufacturing sites across the country. He has hands‑on experience with every major OEM in the field—Hurst, Cleaver-Brooks, Fulton, Johnston, Miura, Donlee, Superior—and advanced burner/controls platforms from Webster, Limpsfield, Weishaupt, Power Flame, Autoflame, Siemens, Honeywell, and Fireye. Factory-trained on multiple systems and a graduate of Broome County College’s Management program, Dan blends deep technical fluency with the leadership skills essential to running high-stakes service operations.
At Keller Mechanical, Dan directs the day-to-day work of our field technicians, architects continuous-improvement training, and spearheads an “always-stocked” inventory initiative that keeps service trucks and warehouses ready for rapid response. His approach is rooted in two convictions: safety is non-negotiable, and client downtime should be measured in minutes, not hours. Whether he’s tuning a low-NOₓ burner or mentoring a new hire on proper lock-out/tag-out, Dan insists on doing the job right the first time and documenting the lessons so the entire team levels up.
Dan’s philosophy is captured in his favorite maxim, a line he often writes on the shop whiteboard:
“We are what we repeatedly do. Excellence then is not an act, but a habit.”
He believes high standards are forged under pressure and maintained through discipline—an outlook he applies both on the job and off. Outside of work, Dan tackles 32-mile rides in the Florida heat to stay mission-ready and previously logged dozens of 50- and 100-mile charity cycling events for the Benedictine Health Foundation in New York. A lifelong “car guy,” he spent years restoring a 1978 Malibu from the frame up and still carves out time to pursue his other passion—aviation—as a licensed pilot.
Ask any colleague and they’ll tell you the same thing: Dan is the professional you call when precision matters, stakes are high, and the clock is ticking. He measures success by the reliability of the systems he services and by the growth of the people he mentors—proof that, for Dan Provencher, excellence is truly a habit.
