Chestnut Oak Associates was founded in 1989 by Joanne Sullivan, George Colli and Kenny Brough. Their offices have resided across from the Town Hall at 76 Mountain Road for 35 years serving the people of Suffield and the surrounding towns. In 2011, Chris Colli became broker/owner of Chestnut Oak, a role he continues to maintain today.
The Chestnut Oak’s motto is “Your Hometown Realtor.” The agency clearly recognizes the importance of giving back to the community in the form of volunteering, sponsorships and donations.

The founding member, Joanne Sullivan, sadly passed away in March of 2022. Joanne was synonymous with Chestnut Oak and epitomized what Chestnut Oak stands for: personalized service, honesty, knowledge, hard work and involvement in the community. She is dearly missed, and the Chestnut Oak team honors her on a daily basis by upholding the high expectations she had in regard to how the office and its agents should operate and treat their clients.
In 2020, Chestnut Oak expanded by opening a second office in Somers, Conn. and currently has a staff of 20 licensed Real Estate Agents.
In 1989 when Chestnut Oak opened its doors, cell phones were not prominent; many agents found themselves using pay phones while out in the field to coordinate with clients and other agents. The internet was years away, fax machines were an agent’s best friend and all the listings were advertised via the newspaper, a ‘For Sale’ sign or direct marketing. Every initial and signature had to be signed in person, prior to e-signature.
Chestnut Oak has had the ability to continually adapt through all of the technological advancements and specifically the real estate industry, to consistently be a top producing brokerage from 1989 to today and looks forward to doing so for many years to come!
