Born in Chicago, Illinois, Kathleen is a graduate of Harrington Institute of Interior Design. After marrying her New England-native husband Bob DeMello, she moved to the Boston area where she established herself and began building her career in space planning, design, project and facilities management, and international corporate real estate for Wang Laboratories, John Hancock Mutual Life Insurance Co., Gillette, and Sun Micro Systems. She served as president of the Boston Chapter of the International Facilities Management Assoc.

In 2004 when Kathleen joined Keller Williams Realty in Nashua, NH she was not new to the real estate world. Before obtaining her license and focusing on commercial and residential real estate sales, she had spent her career acquiring a variety of experience in commercial real estate. Today, she is a proud member of Berkshire Hathaway HomeServices Verani Realty, where she belongs to the BHHS National Honor Society, servicing both commercial and residential needs. Kathy was the 2017 President of the Commercial Investors Board of REALTOR®s for the State of New Hampshire, 2017 President of the New England Commercial Property Exchange, an executive board member of the New Hampshire Association of REALTOR®s as Director of Professional Development and the Womens’ Resource Council as Director of Programs.

While she has a diverse background in real estate, currently Kathleen’s main focus is on office and industrial space as well as multi-family properties. Bringing together investor, property and tenant for an ideal partnership is just one example of how she works for her clients. She was able to do just this for a charter school in Nashua, making it one of her most memorable negotiations to date.
