Mark C. Willis


Mark conducts a broad civil litigation practice with an emphasis on complex commercial litigation, financial services litigation and real estate litigation.

Mark has substantial experience in all aspects of civil litigation including successfully representing clients in trial, evidentiary hearings to obtain a preliminary injunction, administrative hearings, arbitration and mediation. In addition, he frequently appears in bankruptcy and federal and state appellate courts on behalf of his corporate clients. With his broad litigation experience and emphasis on achieving his clients' specific business goals, Mark also assists corporate clients in managing risk management issues to minimize litigation exposure as well as negotiating and drafting various commercial, construction and lease agreements. He also conducts annual continuing legal education courses regarding landlord-tenant, civil litigation and real estate litigation matters.

While Mark predominately represents clients in the State of Colorado, he has been admitted pro hac vice and successfully litigated cases in Alabama, Illinois, Texas, Montana, Georgia, Iowa and Wyoming.
