Move down to Y'All Street after finishing MBA at T30

Reading a WSJ article that Dallas - Fort Worth area has been and is becoming a financial hub. Finishing up a T30 MBA in eastern US with minors in Finance and Enterpreneurship. Have a BA and MA in a Social Science discipline. What is the Dallas Fort Worth finance like? Have heard get pigeon holed in Oil/Gas in Investment Banking. Know American Airlines is in DFW. Any other large employers?
