Jeffrey W. Keiser

Attorney & Founder, Keiser Law

Jeffrey W. Keiser is a Texas-licensed attorney with over 25 years of experience at the intersection of law and business. His career spans two distinct chapters — over a decade as a partner in a law firm serving closely-held and family-owned businesses, followed by nearly 14 years as an executive vice president leading operations, finance, legal, and strategic growth for a multi-state enterprise.

That combination of perspectives — the attorney who understands the courtroom and the executive who's lived in the boardroom — is what defines his approach at Keiser Law. Jeffrey doesn't just advise business owners on what the law requires. He helps them think through what the business needs, how a decision will play out operationally, and what it means for the long-term health of their company and family.

Jeffrey founded Keiser Law to bring sophisticated, general-counsel-level guidance to closely-held businesses — the kind of companies where every owner wears multiple hats, where the personal and professional are deeply intertwined, and where the stakes of every decision are felt directly. He works with startups laying their first foundation and established companies planning their next chapter.

Professional History
