Betty Newell, the longtime president and chief executive officer of the Hamburg Chamber of Commerce, has retired.

Newell, 58, who was named president in 1995, stepped down to concentrate on her health and her family, according to an announcement from the Chamber.

The Chamber board appointed Cynthia Galley as interim executive director. She had been director of administration of the Chamber for two years. Erin Erickson was appointed interim senior director of marketing and business development, and she will serve as the Chamber’s chief marketing officer.

Newell was serving as marketing director of McKinley Mall when she was elected vice president of the Chamber in 1990. She oversaw the creation of numerous tourism projects, which led to the publishing of the Chamber’s Hamburg Visitor’s Guide.

She was a charter member and board president of Lake Erie Seaway Trail Center and the Town of Hamburg Domestic Violence Advisory Board, and she facilitated the Hamburg Community Forum for more than 15 years. Newell also served on the Hamburg Youth Services Consortium, Western New York Chamber Alliance and Buffalo Niagara Partnership’s Who Does What? initiative, which studied the delivery of tax-paid services throughout Erie County. This study spurned the Chamber’s 2001 Who Does What in Hamburg? study, which analyzed the delivery of police, recreation and public works services in the town and its incorporated villages.

Newell also is credited with the growth of the popular Hamburg Chamber of Commerce Farmers’ Market, which has operated in the Village of Hamburg since 1977.
