He’s worked in many fields related to construction and building, including civil engineering, excavation and concrete fields, and owning and operating a water well contracting business. An entrepreneur of 30+ years as well as the owner and manager of several commercial properties, Jim initially got into real estate because of his interest in commercials.

His hobbies include working with his team of Shorthorn Oxen, Chip and Dale, skiing with his two daughters and wife, and hiking (especially on Mount Monadnock).

Her favorite part about living in the Monadnock Region is the proximity to major cities (just a quick drive to Boston, Providence, Manchester, and even NYC) while still being out in the woods and set away from it all. She also loves the countless outdoor activities we get to enjoy all year long like hiking, snowshoeing, swimming, fishing, and everything in between! With mountains to hike, lakes to paddleboard on, delicious restaurants to enjoy, and bald eagles and loons to spot, Mandy, her two daughters, and her husband are never bored.
