Read what some of our real estate clients have to say.
Park City isn't simply where I work - it's the community I've spent more than two decades helping people call home.
As a Real Estate Advisor with Summit Sotheby's International Realty, I've guided clients through more than 470 successful transactions across Park City, Heber City, Midway, and Kamas. I specialize in luxury homes, ski-in/ski-out properties, golf communities, condominiums, new construction, and relocation, combining thoughtful pricing strategies, strong negotiation, creative marketing, and responsive communication to deliver exceptional results.
My commitment to the community extends beyond real estate. I'm the author of Park City Explorer, a longtime real estate blogger, former President of the Park City Board of Realtors, and recipient of both the Utah Association of Realtors President's Award and the Park City Board of Realtors Meritorious Service Award.
Whether you're relocating, purchasing a vacation home, investing, or preparing to sell, I'd welcome the opportunity to help you navigate the Park City market with confidence.
