Witalisz & Associates Real Estate Celebrates Top Producers


Witalisz & Associates Inc., one of the leading boutique real estate firms in Western Massachusetts has much to celebrate again this year. Their team of top producers continues to impact the local real estate market all while supporting their area communities.   

Diane Massey, the company’s resort and second-home property specialist, earned the Top Producer spot at Witalisz & Associates once again this year by producing more than $3.6 million in sales. In servicing a broad area inclusive of the Pioneer Valley and the Berkshires, Diane has single-handedly dominated the Tolland market by representing 45% of all homes sold. Diane’s real estate career extends more than 13 years and her specialty of developing unique marketing plans for niche markets is extraordinary. “Diane brings a dignified and thoughtful approach to the way properties are bought and sold.” Witalisz says. “She is a tremendous asset and we are delighted to have her on our team.” Diane is licensed in both Massachusetts and Connecticut and resides in a lakecommunity with her husband Greg. She also owns The Berkshire School of Etiquette in Lenox, MA.

Denise Calvo-Berndt had another banner year in 2015 with more than $3 million in sales. As the owner of a construction and development company, Denise utilizes her business acumen, knowledge of the market, and experience in the real estate industry to help numerous investors establish their portfolios with significant returns. Denise also has a passion and personal interest in assisting military families - as her son has served in the armed forces. “I have worked with many franchises and real estate companies over my 20 years in the business,” says Calvo-Berndt, “and my affiliation with Witalisz & Associates is like no other. Their support, knowledge and professionalism has helped catapult my career and I feel very lucky to be a member of such a terrific team!”
