Sean Kalman
Nantucket Realtor™
With a passion for real estate spanning over three decades, I transitioned into the industry in 2013 after dedicating 14 years to being a stay-at-home mom. My journey began with the development of two subdivisions in Amherst and Chester, NH, culminating in the successful creation of the Village at Oakwood, a vibrant 55+ community in Derry, NH, which we proudly launched in 2019. Seeing the 30 single ranch-style homes at our Derry development sold out within two years was immensely rewarding, setting the stage for our next venture, Colby Farms, where we are now building single-family homes in Chester, NH. My husband and I are now proud to say we live in the town of Derry in one of the condos we built!
