In April 1969 at the first annual meeting of the Association of Home Health Care agencies in New Hampshire, the seed was sown that developed into North Country Home Health and Hospice Agency. Mrs. Caroline Gale, Chairman of the Lin-Wood Home Health Agency Board served on a panel regarding funding. In a discussion after meeting a remark of “could our agencies get together?” brought about several meetings with a few dedicated people.

Exactly one year later, April 1970, Littleton and Lin-wood Home Care Board of Directors started planning for an agency merger, and in April 1971, after finding a Director, North Country Home Health Agency became a reality. A main office was established in Littleton at 97 Cottage Street, and a small office was established in Lincoln. Then, in January 1972 the Lisbon District Nurse Association joined the agency, and later that fall the Board voted to serve the Woodsville area, prompting the establishment of a third office in Woodsville. The Agency continued to grow, adding programs and staffing. In 1994, they obtained their Hospice Medicare certification. The main office in Littleton, after moving to join space with Ammonoosuc Community Health Services on Mt. Eustis Road in 1989, established its present home at 536 Cottage Street in 1995.

In 2015, North Country Home Health and Hospice Agency merged with Northwoods Home Health and Hospice in Lancaster, and the Berlin Visiting Nurses Association. The Agency now was serving patients in all of Coös County and the northern part of Grafton County. In 2016, NCHHHA joined North Country Healthcare. In 2019, NCHHHA added an in-home Palliative Care Program, and in conjunction with Weeks Medical Center in 2022, will offer outpatient palliative care appointments to the community. In 2022, NCHHHA expanded their service territory south to include Plymouth, New Hampshire and surrounding towns.
