Lake City, beginning as an associate with Berman & Giauque and later as a partner in Berman & Anderson; Hansen & Anderson; Anderson & Watkins; and Anderson & Karrenberg. After he returned to the practice of law in 2014, he was of counsel with Winder & Counsel, then was a partner at Lewis Hansen, and then practiced at Law Offices of Rocky Anderson until 2021, when he wound down his law practice and volunteered full-time as Executive Director of the Justice Party (later named Allied Justice). He specialized in civil litigation in several areas of law, including antitrust, securities fraud, commercial, product liability, professional malpractice and civil rights.
