During law school, Chelsea worked as a litigation law clerk at a boutique oil and gas firm in Denver and held a clerkship with the U.S. Attorney’s Office for the District of Colorado. She acted as a senior staff editor and contributor on the University of Denver Water Law Review and worked as a teaching assistant for first-year Civil Procedure students.

Chelsea is dedicated to serving the Colorado community. She serves as Fundraising Chair for the Rose Andom Center’s Young Professional’s Council, an organization that co-locates Denver organizations serving domestic violence survivors. She is also a part of the 2018 Colorado Oil & Gas Association Energy Generation (EnGen) Leadership Program. She volunteers as a tutor at University Prep, a tuition-free public charter school, and participates in the professional mentor program at the University of Denver Sturm College of Law.
