Meet Denise

Denise Cosby is a dedicated REALTOR with over 15 years of experience in marketing and selling residential and commercial real estate. Denise obtained her real estate license and joined ERA The Norton Group, Somerville under then-broker Donald Norton in 2005. The Norton Group dismissed the franchise name ERA around 2010 and remained The Norton Group where Denise continued to list, sell and rent properties until 2017 when the company dissolved due to the death of Mr. Norton.
In 2009, Denise lost her 21-year-old son to murder. The heart-wrenching experience led her to write a book and become a published author. “Murder at Harvard’s Kirkland House – A Mother’s Worst Nightmare.” She also hosts an advocacy program for victims of violence on zoom called “The Just in Time Initiative” and invites professionals and victims to share and learn about the journey of surviving murder.
In 2017, Denise joined Century 21 Northeast and in 2020, Denise decided to join The Messina Realty Collective and remains a REALTOR representing Sellers, Buyers, and renters and offering referrals to out-of-town buyers.
Denise continues to work for Nightingale Homes Realty where she continues to list, market, and advised sellers and buyers as she helps them negotiate deals.
Remember, I love Referrals!
