The business members of Middlesex West transitioned to neighboring Shirley-based Nashoba Valley Chamber of Commerce, a process Nashoba Valley expects will take some time, according to a Jan. 10 press release from the Nashoba chamber. "This is a bittersweet moment for many of us," Melissa Fetter- hoff, president and CEO of the Nashoba Valley Chamber, said in the release. "For years, our two chambers have been great neighbors, sharing resourc- es, hosting joint events, and supporting each other's success. We are truly honored that the MWCoC Board has chosen the Nashoba Valley Chamber to continue supporting these local businesses, and we welcome them to our growing family." Middlesex West had been left without a leader since previous executive director Jenna Amara stepped down from the role in November. Amara, who had been the chamber's sole full- time equivalent employee, now serves as the managing director of CoWorks @ Vita Therapia, a Westford-based coworking space and business support provider. Founded in 1989, the Middle- sex West Chamber of Commerce had 240 members as of June 2024, making it the 12th largest chamber in Central Massa- chusetts when ranked by total membership, according to data compiled by WBJ's Research Department. - Story by Mica Kanner-Mascolo Middlesex West Chamber closes, transitions members to Nashoba Valley Melissa Fetterhoff
