Real estate company Benoit Mizner Simon & Co. is opening a new office in Weston and Wellesley.

Amy Mizner, Sheryl Simon and Debi Benoit, principals at Benoit Mizner Simon & Co., started their realty business venture together in the fall 2010. Since then, the principles have added more than a dozen new members to the firm, according to a statement. The six new sales associates include Chris Owens, Pam Dennehy, Traci Shulkin, Tanya Tanimoto, Jack Guerin and Ilene Wigetman. Tiffany Sidhom was named the office director for the Weston location.

In Wellesley, Kristine Beimford will serve as office director and sales associates include Wyndham Flaherty, Michelle Roberts Walsh, Jared Parker, Chelsea Robinson, Lynn Donahue, Donna Maley, Alice O’Connor and Betsy Hargreaves. Abbie Morse was hired as the firm’s marketing coordinator.

"We’re thrilled to be able to bring the area’s top-notch sales and service people on board," said Mizner.

The new Weston realty office, located at 450 Boston Post Road, will open on Feb. 3 with an open house, according to a statement. The new Wellesley office, located at 54 Central St., is scheduled to open mid-February.
