He has a Bachelor of Science degree in Petroleum Engineering from Texas A&M University, and spent the first five years of his professional career as a drilling and production engineer, drilling offshore wells for oil and gas companies.

He also provides legal concierge services to executives and key employees faced with a need for individual legal advice and representation.

Outside the Office
