Mark is an excellent realtor. When my husband and I moved to CO, Mark helped us find a home. Fast forward almost 4 years later, Mark recently helped us sell our home and find a new one. Mark is an expert at his job. He has your best interest in mind 100% of the time. He’s a great listener, always there for you when you need him, and always makes sure you get what you want. The amount of work Mark does behind the scene is amazing. Mark has great connections and always gets the job done. No wonder why he’s the #1 realtor in Colorado. We are both grateful to have worked with Mark. If you’re looking for a home in the Denver metro area, go with Mark, he’s the best.

Mark is in a league of his own in downtown Denver real estate. An expert on the market, he skillfully put together a deal that tried to fall through several times. He’s patient and detailed with the assistance of Joe. They make a great team.

I had the best experience working with Mark Callaghan. His knowledge and ability to organize is amazing. He listened to what I described as important in my search, and asked me questions and shared ideas I had never thought of. Mark is a true professional not only to me, but the community, brokers, and agents around him. His responsiveness to answering my emails and calls truly exceeded my expectations. He never missed a detail. I would recommend him to anyone, and I do plan to work with him again in the future. Mark is awesome!

Mark is the quintessential real estate marketing genius! The most effective, efficient and epic real estate transaction in my life. He handled it with ease and professionalism. I applaud he and his team! Would HIGHLY recommend Mark if you want results!

Mark was an amazing realtor for us. He went well above and beyond the call of duty and made what can be a stressful process smooth as silk. Highly recommended.
