Richard Mark is president and CEO of Ameren Illinois Company. He is responsible for electric and natural gas distribution to more than 1.2 million electric and 806,000 natural gas customers across three-quarters of the state of Illinois. Ameren Illinois' complex delivery system includes approximately 4,500 miles of electric transmission lines, 45,700 miles of distribution lines, 18,000 miles of natural gas transmission and distribution mains and 12 underground natural gas storage fields. Ameren Illinois is a subsidiary of Ameren Corporation which is ranked 373rd of the Fortune 500 companies.

Before his appointment as CEO, Mark was senior vice president of Ameren Missouri Customer Operations and was responsible for electric and gas distribution to more than 1.2 million customers across central and eastern Missouri including the greater St. Louis area. Mark also oversaw Customer Services Operations, Community Relations, Communications, Customer Satisfaction and Corporate Giving for Missouri’s largest utility.

Mark joined Ameren in 2002 as vice president of Customer Service. In 2003, he became vice president of Governmental Policy and Consumer Affairs. In just two short years, he rose to the position of senior vice president of Ameren Missouri Energy Delivery - becoming the first African American to hold this position. In 2009, Mark was promoted to senior vice president of Customer Operations - a position that encompasses Ameren Missouri’s Energy Delivery but was expanded to meet customers’ energy needs of the future.

To ensure a secure energy future for Ameren customers, Mark is leading a Strategic Customer Initiative focused on promoting energy efficiency, smart grid technologies and customer-based energy generation, or distributed generation. His team’s goals are to deploy advanced technologies, tools and services to enable customers to manage their energy usage and costs while enhancing the electric grid.

Prior to joining Ameren, Mark spent six years as president and chief executive officer of St. Mary’s Hospital in East St. Louis and five years as chief operating officer. Mark also served 10 years as chairman of the East St. Louis District 189 Financial Oversight Panel.

Mark serves on a variety of boards and organizations including Enterprise Bank and Trust, Madison Mutual Insurance, Major Case Squad of Greater St. Louis, and the St. Louis Police Foundation. He has received three honorary doctorate degrees for his civic and community work, as well as numerous awards and honors; most recently Mark was recognized by Savoy magazine in its 2014 spring issue as one of the Top 100 Most Influential Blacks in Corporate America. In 2012, Black Enterprise magazine named him one of the 100 Most Powerful Executives in America. His other honors include the NAACP’s Inspiring St. Louisan Award of 2011, St. Louis Business Journal’s Ten Years of Influence of 2010, St. Louis Business Journal’s Most Influential Energy Executive of 2010 and many more.
