An associate in Armstrong Teasdale’s Litigation practice group, Colleen Kinsey handles a range of disputes for clients of all sizes. Her main focus includes representing clients, including hospitals, physicians and nurses, in all types of medical malpractice, professional liability, breach of contract and other health care claims, in addition to commercial litigation and consumer fraud matters.
