Community Partners Inc., a 50-year-old behavioral health organization in Biddeford, will merge with Spurwink Services at the start of the new year.

Financial terms of the deal were not disclosed.

The combined nonprofit will retain the name Spurwink Services and continue each organization’s history of providing service to Maine people with intellectual and development disabilities, autism, and behavioral health and medical needs, according to a release from Portland-based Spurwink. The merger requires regulatory approval from the Maine Department of Health and Human Services.

“Our missions are fully aligned and both organizations have reputations for high quality, client-centered services,” said Alistair Raymond, chair of the Spurwink board of directors, in the release. “Together, we will be able to offer a full continuum of care and services from early childhood through a person’s lifetime, and meet a wide range of behavioral health, IDD and medical needs.”

Eric Meyer, Spurwink’s president and CEO, and Francoise Paradis, Community Partners’ chair, said the merger will allow the combined organization to better provide critical behavioral health services, improve client care and continue to deliver community-based services to clients throughout the state.

The staff of Community Partners will be retained in the merger.

“There is great depth of experience in the CPI staff and their expertise, skill and commitment are essential to a successful merger,” said Kristen Farnham, Spurwink vice president of development.
