Mr. Lonnquist retired from the practice of law but remains a friend and mentor to the firm. 

Mr. Lonnquist first clerked for the Colorado Supreme Court, and then joined a mid-sized Denver law firm for five years before being recruited to the legal staff of a Fortune 200 company. After two years, he relocated to Washington, D.C. to serve as the company's registered lobbyist and head of its public policy arm, a position he held for ten years. After a year in New York as general counsel for a merchant banking firm, he returned to Colorado and has practiced law here uninterruptedly since 1990.

Mr. Lonnquist worked overseas for a major New York bank, managed legal projects employing up to 100 outside litigation attorneys, represented clients on national radio and television programs, and has recruited and managed a first tier cadre of lobbyists, complementing their efforts with a team of pollsters, economic researchers, public relations specialists, lawyers, and legislative and communications strategists.

With a practice focused in business law, contracts, litigation, mediation, and negotiation, his clientele derived primarily from referrals of his clients and from other attorneys. He always took a personal interest in the client's broader interests and their legal matter of immediate concern. His counsel tended toward the practical, not the theoretical, and was designed to serve the client beyond current concerns.

Mr. Lonnquist's litigation practice was primarily Colorado state court based, though he is admitted to and has appeared before the U. S. District Court in Colorado, the U.S. Bankruptcy Court, and the 10th U. S. Circuit Court of Appeals.

Mr. Lonnquist received his Juris Doctor degree, with distinction, from the University of Nebraska College of Law, and has current membership in the Federal Bar Association, the Colorado Bar Association, the Arapahoe County Bar Association, and the American Association for Justice. He serves on the Board of Directors of the Cherry Creek Chamber of Commerce.
