Coldwell Banker Residential Brokerage

Looking to sell your property, buy a new home, or just need some expert real estate advice?

About
Real estate is my passion and I love helping customers make their dreams a reality. I believe in building connections and providing support that goes beyond a business relationship. For me, clients are an extension of my family and friends.

I bring enthusiasm, energy, and trust to my role as a Realtor. As a full-time agent I understand the real estate market inside and out, the economics of buying and selling, and how to leverage all the tools to get the best results for my clients.

I have been a Realtor since 2002 and have helped hundreds of clients with their real estate transactions. I am a lifelong resident of Plymouth, where I live downtown with my husband and two dogs—and I have extensive knowledge of Plymouth County and the Upper Cape!

Mark F.
Plymouth, MA - Jul 10, 2017

Kelly was great. When I was looking for a realtor, I was specifically looking for someone who communicated and made me feel like I was number 1. Kelly did that and more!!! She made me feel comfortable throughout the whole process and she get to see first hand some of the headaches I had with the tenants at the building. She was everything and more...highly recommend!!!

Initial contact from Agent Pronto was very quick-everyone we spoke with was very pleasant and helpful.
I can't speak highly enough about our experience with Kelly McKeown. She was awesome and very patient with our "little quirks". She walked us through the whole process, making our purchase as smooth as it could possibly be. Agent Pronto and Kelly McKeown are both highly recommended!
