Steve Thielsen

Steve Thielsen · Broker, engineer, builder

Steve reads the building as well as the market.

The structure, the systems, the lot, the permits and the contract, read as one connected decision. Steve spent fourteen years in the building trades and twelve in technical sales / electrical engineering before a real estate career that began in 2007, and it changes what your sale or purchase looks like.

What clients tend to notice is not the credentials. It is that problems surface early, technical findings get explained plainly, and the work continues after the interesting part of a transaction is over.

Seller · Santa Rosa

Steve is a true straight shooter with a deep understanding of the local market, and his guidance on pricing was spot-on.
