Martin Enegren

Information and Technology Director

As Martin Enegren grew up in the northeast of Kansas, he realized the name “Enegren” was nearly synonymous with entrepreneurship and business ownership. So when the opportunity to start up an IT company in Wichita presented itself, the decision was clear. Having served in the United States Air Force on nuclear weapons systems and later having worked on the systems that control flight simulators for Beechcraft, information technology became a passion and life-long pursuit. Enegren Computer Service was started in 1989 and since that time has grown a national clientele with diverse products and services as the industry has changed. In the 1990’s they became a local internet service provider, and in 2005 they became a phone service provider. The year 2010 began their work in surveillance and security systems, and just this year they are now offering audio, video and lighting systems as well. Information technology is an ever-evolving industry and the business world is increasingly dependent on its IT systems for customer service, productivity, accuracy and expansion. For this reason, Martin’s contribution to Mid-Continent Energy Exchange in the area of IT support will be vital to excelling in this technology-driven business world.

Preston Withers

Director of Finance

Preston Withers is a born and bred Kansan, growing up in the flatlands of windy Western Kansas. He holds a Bachelor of Science degree in Finance from Kansas State University and has been in the Oil and Gas business for 23 years. Early in life, Preston learned from his dad that necessity is the greatest motivator. In the mid 1980’s, the Withers family was going broke purchasing retail natural gas at sky-rocketing prices to power the irrigation wells on their farm. As a result, the family acquired 3 abandoned wells and successfully recompleted them in the Hugoton-Chase reservoir and the rest is history. Preston has continued drilling and developing wells ever since. In addition to Oil and Gas, the family’s passion for agriculture has afforded them real estate in Arkansas, California, Kansas, Oklahoma, and Texas growing a multitude of commodities including corn, cotton, peanuts, pinto beans, rice, sorghum, soybeans, sweet potatoes, sunflowers, and walnuts. In recent years, they have also pursued a ranching venture by building a Black Angus cow/calf operation in Southwest Kansas. Preston looks forward to using his experience in the industry to make Mid-Continent Energy Exchange your choice for buying and selling your interests in the future.
