Robert Rosenthal spent years parachuting into remote wildfires. Then he traded a smokejumper helmet for dental loupes.

Rosenthal worked as a smokejumper at the North Cascades Smokejumper Base in Winthrop, Washington, from 2010 to 2017. That puts his first career directly inside the world we ranked among the toughest jobs in 2026: parachuting into remote terrain, carrying heavy equipment and attacking wildfires before they grow.

What makes his résumé stand out is what he was doing between fire seasons. According to the University of Washington School of Dentistry, Rosenthal repeatedly returned to school while smokejumping and eventually chose dentistry, a profession already familiar through his father and his late sister.

The University of Washington’s RIDE program explains the rural dental-training pathway Rosenthal followed.

He graduated from the University of Washington School of Dentistry in 2021. His current practice biography at Sawtooth Dental Care says he graduated with distinctions, received the Dennis P. Duskin Inspirational Award from his classmates and was inducted into the Omicron Kappa Upsilon dental honor society.

After graduation, Rosenthal worked as a community-health dentist in Brewster before practicing in Twisp, near the same North Cascades communities where his smokejumper career had taken shape.

The transition is striking because neither profession is a side hobby. Smokejumping requires years of wildfire experience, parachute training, physical conditioning and judgment under dangerous conditions. Dentistry requires a doctoral degree, clinical training, licensure and precision measured in millimeters.

That is the kind of combination this Career series is looking for. Rosenthal belongs beside saturation diver Chris Lemons and veterinarian-mountaineer Ed Viesturs: people whose résumés cross disciplines that each take years to master on their own.

Rosenthal’s career also has a useful through-line. Smokejumping brought him into small Western communities where specialized services can be difficult to reach. Dentistry ultimately brought him back to serve one of those communities in a completely different way.
