Deputy Commissioner Mason Trumble is an outdoor educator with expertise in promoting and expanding access to outdoor recreation through innovative partnerships between public and private sectors.

In his past role as part of REI’s New England leadership team focused on experiences and brand engagement, Mason worked with many non-profit partners across the state on projects ranging from pollinator pathways to improved access for backcountry hiking and camping. One of his most meaningful achievements at REI includes designing “Cheers for Public Lands,” a political advocacy campaign that built crucial public support for the recently passed constitutional amendment to protect state lands here in Connecticut. Mason is the founder of the Connecticut Outdoor Recreation Alliance - an coalition of organizations focused on protecting and promoting Connecticut’s outdoor recreation resources.

An avid outdoorsman and trained outdoor guide, Mason moved to Connecticut after working as a NOLS (National Outdoor Leadership School) instructor in Utah, an operations manager for a whitewater rafting outfitter and a conference director in Maine. He holds a bachelor’s degree in business and a master’s degree in outdoor education.
