About the firm

Dorwart Law is a 30+ lawyer firm handling the kind of work typically reserved for the largest NYC firms — billion-dollar M&A, complex regulatory matters, and bet-the-company litigation. Dorwart regularly serves as primary outside counsel to institutions with tens of billions in assets.

For more than 30 years, leading financial institutions, energy companies, and private equity sponsors like George Kaiser, BOK Financial, and Switchgrass Holdings have trusted Dorwart not because of our size or location, but because of our judgment, experience, and results. We operate from Tulsa and Dallas by design. Lean teams. Direct partner involvement. Faster decisions. No unnecessary layers. The result is simple: major-market sophistication with materially better efficiency and value.

Dorwart is built for clients who need elite legal work — and expect it to be delivered without friction.
