Derek Colen is an outstanding real estate agent. Great person with a fun, up beat personality to work with. He was professional, knowledgeable, and responsive, answered my calls and questions. He helped me through every step of the process of getting the condo I wanted and went above and beyond. I highly recommend Derek Colen to anyone looking to buy or sell a home.
