About Hydro Dynamics
Doug Obermeier — Owner & Operator
Hydro Dynamics is a self-performing industrial contractor based in Hortonville, Wisconsin — all work performed directly, with a single point of accountability.

Apprenticeship Training — The Traditional Way
Doug completed state-indentured apprenticeship training in three trades — millwright, pipefitter, and welding/metal fabrication (GMAW/MIG) — through Fox Valley Technical College. The coursework was completed through evening classes while working full-time in the industry — years of nights in the classroom after days in the plant.
This is the foundation of the firm’s credibility: training earned the traditional way — in the trade, under journeymen, to state apprenticeship standards. Few contractors in the region hold apprenticeship credentials across all three trades.
