Pat Barron
Energy Efficiency Services Coordinator
pat@groundworkcolorado.org

Pat is no stranger to extending a helping hand to members of the community in need of assistance. She recently retired after 36 years with the State of Colorado as a staff and administrative assistant. Pat primarily worked with the Office of the State Public Defender, which provides legal representation to the criminally accused who are unable to afford private legal representation. After a short-lived stint as a retiree, she realized that she had many productive years ahead of her and decided to go back into the workforce. She was faced with the choice of continuing in the field of providing legal services in the private sector or moving into the nonprofit sector, providing services in furtherance of the mission of Groundwork Denver. The choice was easy and thus, she became a member of the Groundwork Denver team to help our clients connect with all of the energy efficiency assistance and resources available to them.
