Crew credits.
Names on the loops. Roles, licenses, signature initials, and what each person reads on lunch break at the workbench. Read this page the way you would read the inside fold of a long-player record — credits in big italic display, role and credentials in mono beneath. Six people, one shop.

Lars opened the shop in November 2011 after eleven years as a journeyman plumber in Helena and Bozeman, the last three on hydronic crews up Bridger Canyon. He runs lead on every boiler set and every commissioning. He answers the phone on cold-snap nights and is signed off as engineer of record on every system in the job book.

Wendell came on as a contract commissioning engineer in 2019, after thirty-five years as a state plumbing inspector. He runs the weekend rota and is the second signature on commissioning visits for every system that ships with snowmelt. He has been to more mechanical rooms in southwest Montana than anyone we know, and the binders are better for his eye on them.
Always open to a conversation.
The shop is six. We are not actively hiring as of the publication of this almanac, but we are always open to a conversation with experienced hydronic technicians in southwest Montana, with apprentice candidates with mechanical aptitude and a willingness to spend Saturdays on cold-snap rota, and with designers who can read a Manual J and a Caleffi spec sheet in the same afternoon.
Send a short note to hiring@headwatershydronics.example, or stop by the shop on a Friday after 14:00. We will be at the workbench, and the coffee will be on.
