The Missouri Public Service Commission regulates investor-owned electric, steam, natural gas, water and sewer and telephone companies. Its mission is to ensure Missouri consumers have access to safe, reliable and reasonably priced utility service while allowing those utility companies under our jurisdiction an opportunity to earn a reasonable return on their investment. The PSC also regulates manufacturers and retail dealers who sell new and used manufactured homes and modular units. The commission was established in 1913. The PSC is comprised of five commissioners, who are appointed by the governor.
Division Descriptions
Wess Henderson, Executive Director
Executive Division
As appointing authority, the executive director directs the management, administration, operations, information and technology services and training, and work product of the Missouri Public Service Commission. There are five distinct divisions comprised of attorneys, accountants, engineers, economists and other professional staff who support the commission by providing legal and technical expertise. The executive director is responsible for leading the agency’s strategic planning; technical and administrative policy and procedure development and implementation; and budgeting process. The executive director ensures work product of professional and technical staff meets or exceeds substantive standards within prescribed deadlines and serves as liaison between the commissioners and staff, between the commission and the Department of Economic Development and serves as a primary contact with external entities as appropriate.
Dana K. Joyce, Director Administration and Regulatory Policy
Administration Division
The Administration Division is responsible
for managing the Commission’s human and fiscal resources.
The division has agency-wide responsibilities
for the annual budget, strategic planning, fiscal services and
procurement, human resources and payroll. The Regulatory Policy and
Public Information Department, another unit of the division, develops
and distributes press and consumer information on current PSC
activities, develops educational materials, maintains the PSC Reports,
and deals with media requests. The Legislative Coordinator, the
agency’s primary contact person with the General Assembly, is also
assigned to this division.
Colleen M. (Cully) Dale, Chief Regulatory Law Judge
Adjudication Division
The Adjudication Division is the PSC’s quasi-judicial division. A staff of regulatory law judges handles cases from their filing until their resolution. The assigned judge presides over the hearings, rules on objections and motions, and drafts all orders, as directed by the commission, for that particular case. The Adjudication Division’s Data Center receives all incoming pleadings and issues all commission orders. In addition, the Data Center maintains and preserves the official case files, tariffs and other official documents of the commission.
Kevin Thompson, General Counsel

The General Counsel is authorized by statute to represent the Public Service Commission in all actions and proceedings, whether arising under the Public Service Commission Law or otherwise. Attorneys of the General Counsel’s Office appear in state and federal trial and appellate courts on behalf of the commission and represent the commission’s staff in administrative matters before the commission. The General Counsel also provides legal advice to the commission and each commissioner as requested, as well as to the commission’s staff. When authorized by the commission, the General Counsel seeks civil penalties from persons or companies that have violated the Public Service Commission Law or the commission’s regulations or orders. The General Counsel’s Office also appears for the commission before various state and federal administrative tribunals, such as the Federal Communications Commission and the Federal Energy Regulatory Commission. The division houses the Consumer Services Department, the clearinghouse for all utility consumer inquiries. Consumer Services investigates and responds to complaints to ensure compliance with commission rules and utility tariffs. When a consumer has an issue that is not satisfactorily resolved after an initial contact with the utility, the consumer may call the PSC consumer hotline 1-800-392-4211 for assistance.
