    Welcome to the Greater Merrimack - Souhegan Valley Region!

    The Greater Merrimack-Souhegan Valley Chamber of Commerce promotes the economic vitality and high quality of life of the eleven towns within the Souhegan Valley and the Town of Merrimack, located in southern New Hampshire. We promote collaboration, advocacy and economic opportunities for the businesses and organizations that strengthen our communities, making our region a dynamic place to live, work, and play. Close to everything but rural in nature, our region is an ideal place to locate a business. Residents enjoy terrific schools, close-knit communities, abundant opportunities to enjoy local history, community events and outdoor activities.
