Mary O'Donnell - Real Estate Agent at Gibson Sotheby's International Realty

Local Expertise. Global Connections.

My goal is to help buyers and sellers while having a bit of fun as well. I grew up in Chatham and now live in Harwich. I earned a Bachelor's degree from UMASS/Amherst and a Master's degree from New York University. After college, I worked in NYC and Boston. In the early 90's, I landed back on the Cape and began my real estate career. Since then I have closed over 57 million in sales and enjoyed working with many repeat clients. Let me put my local knowledge and years of experience to work for you.
