About Fiona

Driven, determined and disciplined are three characteristics that describe Missy Lohin. Having spent much of her career in sales, Missy brings her expertise in prospecting, negotiating and creative marketing to every real estate transaction that she represents. For Missy, providing superior client services, no matter the price point is paramount, and she enjoys being a trusted resource for her clients across various life stages.

Missy is a lifelong Massachusetts resident, having grown up in Wayland, and she now resides in Bolton with her family. She loves Bolton and surrounding towns like Stow, Groton, Harvard as they provide a hometown feel, great schools, more affordability than some of the eastern MetroWest towns, yet have the convenience of major metropolitan hubs. When she’s not busy working for her clients, you can find her outdoors—skiing, boating, and enjoying the beauty of New England. Missy is also an active volunteer within the Bolton and Harvard schools as well as Maine Adaptive Sports and the Scleroderma Foundation.
