Bringing You Home to the Mountains
Our History
1992–2004: Our story began as a Metro Broker’s office operating as MacArthur Real Estate, founded by Patti MacArthur, a beloved figure in Steamboat Springs real estate. Known as the “Mother” of Steamboat Real Estate, Patti built her legacy on warmth, encouragement, and the “Golden Rule.” Her vision and values became the foundation of our boutique brokerage.
2004–2020: Patti and her husband Chuck transitioned into retirement in 2004, passing the torch to Mark Stine, who purchased MacArthur Real Estate. Rebranded as MacArthur & Stine Real Estate, the boutique thrived, serving families across the U.S. and internationally. Patti mentored Mark through this period of growth, instilling the philosophy that “change is not easy, but it is good and necessary.”
2021–Today: As we entered a new chapter, we reintroduced ourselves as the Mark Stine Agency. Building on our rich history, we’ve enhanced every aspect of our service—embracing modern technology, innovative strategies, and an even stronger commitment to delivering excellence. With each evolution, our mission remains steadfast: providing a tailored, seamless experience that reflects our passion for the mountain lifestyle.
Meet Mark
Mark Stine’s journey began in Los Angeles, CA, but his heart has always been in the mountains. Raised on a family farm in Southern Illinois, Mark learned the values of responsibility, hard work, and connection—principles that guide his approach to real estate today.
Mark graduated from Eastern Illinois University with a B.A. in Economics in 1985. After building successful careers in software and telecom, Mark discovered his true passion: real estate. Earning his real estate license in 2002 and his managing broker’s license in 2004, Mark brought his expertise and client-first philosophy to Northwest Colorado.
Mark’s connection to Steamboat Springs began in 1987 on a surprise trip to visit his future wife, Corrin. Together, they’ve built a life immersed in Steamboat’s Western lifestyle and ranching community, raising their daughter Makenzie. Makenzie completed her undergraduate degree at Baylor University and went on to earn her Doctorate in Physical Therapy, embodying the same dedication and drive her parents value.
When he’s not helping clients, you’ll find Mark embracing everything Steamboat has to offer—riding horses with Corrin, indulging in the fresh flavors of Mambo downtown or Lupita’s in Oak Creek, savoring the daily delights from Smell That Bread, or supporting the vibrant downtown Farmers Market. Even his loyal four-legged companion, Buddy, relishes their adventures along the Core Trail.
