About Us

Since the founding of the Sotheby's Auction House in 1744, the Sotheby's name has earned the distinction of being the premier marketer of the world's most valuable and prestigious possessions. This reputation is built as much upon exceptional services to clients as on the notable art, antiques, jewelry and other holdings that pass through Sotheby's offices around the world. The Sotheby's International Realty® organization began in 1976, in part to serve clients desiring a complete package of estate services. Building on the impeccable Sotheby's brand image, Sotheby's International Realty® quickly became known for representing extraordinary properties throughout the world.

In 2004, Ed Newton III began his apprenticeship under Michael Mathieu, a thirty year veteran at the time. Specializing in Westborough, they quickly became the number one agents in town and have been ever since. In 2007, they formed The Mathieu Group and in 2010 expanded the team. Their expansion has allowed them to focus in all areas of Central Massachusetts while maintaining a high level of service to clients in Westborough and the surrounding communities. In 2013, they affiliated with Sotheby's International Realty® and started doing business as Mathieu Newton Sotheby's International Realty. Their unmatched chemistry is a byproduct of their complimenting attributes. Together, they provide Veteran experience, world class service, a timeless work ethic, artful marketing, a strong understanding of real estate technology, and an expert knowledge of the Central Massachusetts real estate marketplace.
