Prior to joining Kozak & Gayer, P.A. Charlie was a partner at Preti Flaherty, where he practiced in the areas of Administrative Law & Government Procurement, Health Law, Education Law and Legislation.  He began his legal career as an attorney for the Maine Public Utilities Commission and then served as the first General Counsel for the Maine Health Care Finance Commission.  There, he was responsible for the Commission’s rulemaking and adjudicatory hearing process, and represented the agency in state and federal courts and before the Legislature, from 1984 to 1992.


The focus of Charlie’s practice is on advocacy and creative problem solving for clients with regulatory, reimbursement, or contractual relationships with governmental bodies.  While most of his work pertains to state government health care agencies, Charlie is equally interested and conversant with administrative law issues outside of the health care field and with federal health care issues.  Drawing on his past service as counsel to two government agencies, he has served a wide variety of nonprofit and for-profit clients with diverse and complex regulatory, reimbursement, licensing, and government contracting issues.


Charlie regularly handles hearings and negotiations before a variety of administrative bodies, including the Office of MaineCare services, Program Integrity Unit; Maine licensing boards; and the Department of Administrative and Financial Services, Division of Purchases.  Charlie has extensive experience in state bid preparation and litigation and is regarded as one of the most effective contract appeals attorneys in Maine.


In health law, Charlie has advised and advocated on behalf of hospitals, community health centers, community mental health and social service providers, residential care and rehabilitation facilities, substance abuse treatment providers, providers of services to persons with intellectual disabilities and autism, managed care organizations, health plans, reference laboratories, and others on a wide range of economic, policy, and corporate issues.
