About Mark

Nothing is more enjoyable to me than to serve my clients. I want to open more than just doors for you, I want to unlock your dreams. Having traveled all over this world in my military days in the USAF I have learned to appreciate what we have here in New England. Raised in Dover NH and having ties to the lakes region I decided to settle in Sanbornville NH for 28 plus years. Managing in a growing manufacturing company, serving as a Selectman for 2oyears and 24 years of community service I know how to communicate and how to get things done. Having been from a big family and having my own I realize how important it is it is to find the right home for you. Whether selling or buying the decision is life changing and needs the attention of someone who will be there for you through the whole process. We at Keller Williams consider our self to be your family of real estate professionals, nationally recognized, ready to serve you. Let me serve you!

Skowhegan, ME
Wooded 11 Acre lot on the shore of the Wesserunsett Stream in beautiful Skowhegan Maine. Many opportunities for build or to enjoy time by the stream. That flows down to the Kennebec River. Close to the amenities but offers a remote feel away from the center of Skowhegan. Many other activities surround this area that include rafting, hiking, fishing, in summer and winter sports.
