Please join us in welcoming Sam Kelderman, EI, to RPA as an Engineering Designer based in our Kalispell office, joining our Water & Wastewater Group.

Sam studied chemical and biological engineering at Montana State University in Bozeman, with a background spanning microbiology research, fluid flow modeling, and semiconductor manufacturing. That mix of experience led her to water and wastewater engineering, where she now works on delivering safe, environmentally responsible infrastructure to communities across Montana. She also competed in Division I track and field and cross country at MSU, and grew up in Issaquah, Washington.

Outside the office, Sam trains for marathons and triathlons with her husband, paddleboards, bikes, skis, and gets outside with her German Shorthaired Pointer. She ferments her own food at home, everything from sourdough to kombucha, and coaches elementary school kids in cross-country skiing in Whitefish each winter.

As an employee-owned firm, everyone on our team has a stake in the work. Welcome to RPA, Sam.
