Partner/Owner, Lobbyist

Jim Cole

Jim is a highly accomplished senior executive, consultant, lobbyist and strategist with over 30 years of success in public policy, politics, government, energy, healthcare, financial services, transportation, state budget, local government, education and the nonprofit sector. Over the course of his career he has spearheaded legislation that has resulted in robust energy development, broader access to public k-12 education, enriched opportunities for higher education, higher air and water quality standards, major investments in transportation, and a healthy balance of power between the state and local governments.

Jim immerses himself in learning about his clients’ needs and can put complex issues into relatable terms. He moves people to understand issues first and then support the policies he is advancing. It is because of this strategy and his leadership on oil and gas issues that he was presented with the Denver Business Journal’s “Who’s Who in Energy” award in 2017. 

Some of Jim’s highest accomplishments include creating the Arkansas River State Park, passing the Clean Air Clean Jobs Act and passing the Colorado School of Mines (CSM) Exemplary Institution Act, which enabled CSM to provide one of the highest quality and rigorous research experiences in the nation.

Jim has a Bachelor’s of Science degree from Oregon State University. He has been married 38 years and he and his wife, Mary, have two adult children. Jim is an avid cyclist and has completed nine years of Ride the Rockies and Iowa’s RAGBRAI. He also loves to fly fish and play guitar. His joy is seeing the humor that presents itself in everyday situations and sharing it whenever possible.

Before joining the CLS team in 2012, Zoey managed a successful campaign for a Colorado State Representative. Within the Colorado political arena, she is highly regarded as a strategic operative and lobbyist on advanced industries, human services, arts and culture, economic and workforce development issues; but lobbying the state's powerful Joint Budget Committee is one of her favorite things to do under the golden dome. Her commitment to winning on the complex issues her clients care about and her quick study drove her promotion to partner in 2019.

In addition to learning how to run strategic campaigns, she spent time working on Capitol Hill in Washington D.C. in the office of Congresswoman Gabrielle Giffords, of Arizona.

Beyond her love for hiking and her obsession with her rescued greyhound, Aldo, Zoey is passionate helping others learn, grow and develop. Deeply invested in the Denver community, she is the Assistant Debate Coach at West High School and is the Chairwoman of the governing board for the college access mentoring nonprofit Minds Matter of Denver. Through MMD she also mentors two high achieving young women from low income backgrounds.
