Background & Credentials
Built From the Ground Up — Not a Boardroom
Kosonen Consulting was founded by a career Millwright with over two decades of hands-on experience across power generation — from hydroelectric turbine pits to GE gas turbine overhauls to geothermal fields in Northern California. That field background isn't a footnote — it's the foundation of every recommendation we make.
Specializing in Pelton and Francis turbine systems, with deep experience across gas turbines, geothermal, and industrial turbomachinery — we bring the kind of practical, equipment-level knowledge that only comes from years of working alongside the machinery.
