Heather Peterson

Associate Broker



Minnesota native Heather Peterson moved to the mountains of Park City in 1987. She entered Utah’s fast-paced real estate industry in 2000 and has enjoyed a rewarding career over the following two decades. A successful development agent, Heather specializes in new project sales—including 820 Park Avenue, Empire Residences, Goldener Hirsch Residences, and Sommet Blanc—in addition to residential resale. Heather’s efforts and excellent reputation have resulted in industry recognition; she’s received numerous awards as a top sales agent during her career. Heather served as a director for the Park City Board of REALTORS® and enjoys devoting her energy and time to philanthropic organizations.

Heather holds her Associate Brokers license and partners with Sean Matyja, who is her husband and fellow sales professional with Summit Sotheby’s International Realty. As a team they provide comprehensive real estate expertise paired with a vast wealth of knowledge about Park City and its evolving real estate market. One of them is always available to assist clients or follow up on their questions and needs. Heather and Sean complement each other, both in life and business, each contributing unique strengths and skills to their partnership.

Their philosophy: ‘Your success is our success.’ Heather and Sean’s goal with their clients is to provide realistic expectations, informed advice and qualified guidance—all while providing extraordinary service. Their business model focuses on quality over quantity; the many referrals Heather and Sean have received from satisfied clients are a true testament to the unmatched services they offer and the deep trust their clients place in them. In their own words:

‘You have been very professional and objective throughout this process, which is appreciated. Thanks so much for your time, attention to detail and follow up. You are a pleasure to deal with and display a straightforwardness and integrity not often found with REALTORS® we’ve dealt with in the past.’

‘Heather and Sean are a rare find in any business, and especially in real estate—committed, diligent, competent, responsive, and friendly. You could not ask for a better real estate experience and I could not more highly recommend them.’

When she’s not working, you can find Heather spending time with her family and enjoying all that Park City provides. She and Sean have a beautiful nine-year-old daughter named Zoe, who’s in the third grade. When she’s not assisting clients, Heather cherishes family time, hot yoga, and exploring Park City’s abundance of outdoor recreation—hiking, skiing and biking.
