Neil is an experienced litigator and business advisor. In addition to his well-established eminent domain and real estate litigation practice, he advises the firm’s clients on real estate and business transactions, business and valuation-related litigation, and general business matters.

As a litigator, Neil serves as both a counselor and an advocate for the firm’s clients. He is experienced in all forms of dispute resolution, from mediation and arbitration to trial and appeal. While he strives to reach smart, business-oriented solutions for the firm’s clients, he also understands that such solutions can sometimes only be reached by trying a case.

As a business advisor, Neil serves as an outside “general counsel” to several of the firm’s clients, helping them navigate business formation and transactional matters, employment matters, contracting, and regulatory compliance. On the real estate and land use side, he helps clients with the acquisition, development, lease and sale of commercial property.

Neil has been recognized by his peers in publications such as Best Lawyers in America and Super Lawyers. Prior to becoming an attorney, he served as a legislative analyst for the Texas House of Representatives.
