About Us

Mark Wintzer Company was founded by lifelong friends Mark Thimm and David Wintzer, who share deep roots in Park City. From growing up together at McPolin Elementary to combining over 20 years of experience in construction and engineering, we’ve built this company with a shared commitment to our hometown and the people who make it special.

We understand that building a home is a significant investment—financially and emotionally. That’s why we created our 4 Signature Guarantees as a promise to deliver a building experience that is seamless, transparent, and tailored to your needs. These guarantees are at the core of how we ensure your trust and satisfaction at every step of the process.

At Mark Wintzer Company, we’re proud to provide a level of service and quality that is unmatched in the industry. Our mission is simple: to create homes that exceed expectations while building relationships that last.
