A Maine Tradition

North American Kelp was founded in 1971 by Robert Morse, a marine engineer who was one of the first members of Maine’s Organic Farmers and Gardeners Association. The company harvests and processes kelp year-round with a regular crew of 20+ that swells to 35 during peak harvesting seasons. The kelp is processed in North American Kelp’s facility in Waldoboro, Maine, using processes developed over the past 50 years.
