Mark's Story

My name is Mark Greer. I am originally from Upstate New York (born and raised in the Finger Lakes) and I’ve been in Breckenridge since 2015. I am a hardworking and determined team-player with extensive leadership experience and strong interpersonal skills. While earning Bachelors degrees in Psychology and Chemistry from Hobart College, I played varsity lacrosse and club hockey, worked as a Field Coordinator for the Pre-Orientation Adventure Program and was selected as Leader of a day camp for the City of Canandaigua, NY.  Since arriving in Breck, I have worked for the Breckenridge Outdoor Education Center (BOEC) as a Raft Guide, Climbing Instructor, Course Director, and most recently, the Assistant Ski Program Director. I have made it my mission to fully immerse myself in this wonderful community. I have volunteered and worked with service organizations around Summit County, and I am always looking for the next opportunity to get involved in a community I have grown to love so much.

As an Associate Broker, I take pride in helping people every day. Wherever I am, I am passionate about connecting with individuals of all backgrounds and abilities and sharing memorable experiences. I believe firmly in community engagement and public service, and I like to help others make their dreams a reality.

When looking for a home, I believe that a good community, and a happy, healthy lifestyle, are fundamental necessities. I love seeing people succeed and I look forward to doing everything I can to help you accomplish your goals, whatever they may be. If you see me around town, or out in the mountains, don't be shy, please say hello; I always love to chat, and I am determined to continue to help build an inclusive, and welcoming community!

Here is what some of my clients have to say about working with me...


"Thank you again for assisting Karyn and I in finding a great mountain home in Breckenridge, and in record time – we couldn’t have done it without you!  We were particularly impressed with the speed at which you found exactly the home we were looking for, especially in this challenging real estate market!  Your positive attitude, tenacity and exceptional work ethic no doubt was instrumental to us finding our dream home.  Karyn and I consider you a part of our extended family and we look forward to spending quality time in beautiful Breckenridge! 

 Mark, we wish you the very best of luck in your career.  Based on our experience, we all agree you have a very bright future ahead of you."
 - Paul & Karyn D., CEO/Chairman Fortune 200 Company

"Mark Greer is an exceptional realtor and I am so grateful I had the pleasure of working with him to buy my first home in Summit County. Whether you are a local dealing with deed restrictions and HOAs or a 2nd homeowner wanting to be in the mountains Mark has the work ethic, relationships, and dedication to help you find your dream place. He has so much knowledge of the county and has an amazing team to back him at Cornerstone Real Estate Rocky Mountains. I felt supported and secure from the time I started looking to closing. Plus, Mark has just great energy and is a blast to be around. You cannot go wrong with him as your realtor! THANK YOU MARK!!!"
