Veteran Owned

Whitt Sturtevant is pleased to announce it is now certified as a veteran-owned business and a proud participant in the State of Ohio’s Veteran-Friendly Business Enterprise (VBE) Procurement program.


Most of our work involves representing clients before state utility regulatory commissions, primarily in Illinois and Ohio, but also throughout the Midwest and nationally. We handle matters as straight-forward as customer service complaints, to major rate cases with hundreds of millions of dollars at stake, to everything in between. We also help write legislation pertaining to energy and utility matters, and typically represent one or more clients in all major gas, electric and water administrative rulemakings in Ohio and Illinois. We strive to help clients identify issues before they become problems. To that end, we spend a great deal of time counseling executive and senior management in developing corporate policies and objectives in ways that comply with regulatory requirements.


Whitt Sturtevant LLP is committed to promoting and achieving diversity within our firm and in the greater legal community. We believe a diverse workplace that reflects the diversity in our communities enhances our ability to provide quality legal services to our clients.  Diversity in backgrounds, experiences, and ideas allows us to be creative and innovative in solving problems and responding to our clients’ needs.  It is crucial to our mission of providing quality legal services that are efficient, results-oriented, and cost-effective.

Whitt Sturtevant is a law firm serving the energy and public utility industries. Our work encompasses all aspects of regulatory, trial and appellate practice for regulated utilities and retail energy suppliers. We are one of only a few law firms in the country with One Focus on energy and public utility law. We practice in the Midwest and nationally from offices in Chicago and Columbus.


A guiding principle of our firm is to place our clients’ needs before our own. This means we staff cases based on the needs of each particular matter, not what contributes most to the firm’s bottom line. Our input into strategic decisions is based on our judgment of how the client’s objectives will be met most efficiently, not what will generate the largest bill.
