Mark took care of all the details and kept me informed every step of the way. He told me what I needed to do to have the place ready to show and it was under contract in less than a week from when it was listed and got a very good price. Everything was hassle-free

Mark was a pleasure to have as my realtor. He walked me through the process and came up with a winning strategy to win an offer on my home. During one tough part of the process, he reached into his deep network to get me over the finish line. His years of experience in the local market are a key asset.
