The Sonia Boyajian Story

From route 109 to Belmont.

After years managing the family-owned furniture store, Watertown native and kingpin Sonia Boyajian decided to go in to real estate. She opened her first real estate office on Route 109 in Millis, where the family owned commercial property. A year later, recognizing she needed to work in the communities of Watertown and Belmont where she lived and raised her children, Sonia established an office in Cushing Square, Belmont.

The office address changed; the name did not.

Sonia’s legacy: innovation and community.

When Sonia moved the office in 1983, there were 25 independent real estate firms in Belmont. Today, including Real Estate 109, there are three. One by one, boutique firms closed their doors or merged with chains to survive.

Real Estate 109 has thrived for 36 years because of Sonia's fearless entrepreneurial spirit and dedication to the community in which she lived and worked.

A living database, Sonia remembered the names and details of everyone she worked with, allowing her to connect with her clients in meaningful ways. Whether a birthday card, a congratulatory phone call, or a thoughtful gift, Sonia maintained an unbreakable chain of communication and kept it personal by always hand writing notes.

Sonia embodied the professional, as well as the personal. She never stopped learning and readily embraced technology as the key to staying on top of things. Years before other real estate firms invested in computers, Sonia had them installed in 1983, ensuring that her clients had the most up-to-date information. Long before it became standard practice, Real Estate 109 included professional floor plans for all property listings.

Her pioneering spirit didn’t end there. While Sonia worked and raised four children in Watertown, she also served the community. She was the Watertown Chamber of Commerce’s first woman president, sat on the Great Boston Real Estate Ethics board, served on the first Alzheimer's commission in Massachusetts, was the first woman president of the Furniture Association of New England, and was a trustee of Mt. Auburn Hospital.

Sonia helped her neighbors — new and old — to buy and sell home and continued to do the work that she loved up until the age of 87.

In the tradition Sonia established, Peter and his team of agents continue to support clients as they sell and buy homes and build lives in their chosen communities.
