Explore Eagle County and Summit County, Colorado Real Estate from Berkshire Hathaway HomeServices Colorado Properties was founded in 1971 by John Slevin and is currently owned by his son, Michael Slevin. We started out as a one office company located in Vail, Colorado and then opening our second office in Beaver Creek, Colorado when Beaver Creek was founded as a Colorado ski resort. At that time we had about ten real estate brokers and two offices in the Vail Valley. Today we have grown into a wonderful company with over one hundred real estate brokers, six real estate offices, and one vacation and property management office located in the Vail Valley. We have also expanded into Summit County with the addition of a Breckenridge Office and Brokers who can help buyers and sellers throughout Summit County. We are still family owned and operated and continue to maintain our position in leading real estate sales in the Vail Valley.
