Experience, without the theater
Steve Thielsen is a Petaluma-based Broker Associate with Century 21 Epic, licensed since 2007 and practicing full time in Sonoma and Marin counties ever since.
Before real estate, Steve worked in construction and earned a B.S. in electrical engineering. That background shows up in the work: he reads a property’s structure, systems, and condition firsthand, and he approaches pricing, preparation, and disclosure with an engineer’s discipline rather than a sales script.
In 2016 he earned his broker license—a step beyond the salesperson license most agents hold—and he has built a practice on repeat clients and referrals: sellers of older homes and country property, buyers navigating wells, septic systems, and easements, families handling trust and estate sales, and investors working through 1031 exchanges.
“If it was a scale of 1-10, he’s a 20!”Cj Rockwell · Seller · 2022
