William grew up in Houston with a father who was a trial lawyer and a mother who was a Catholic middle school teacher. In between playing basketball in just about every gym in the city, he recalls hearing stories about his father’s clients and the help they needed and the help that was given. William traveled up north, to Cedar Falls, Iowa, to attend college and play a little basketball. While in college, he noticed that he was drawn to the law-related courses he took. As his college career came to an end, he began talking to his parents about law school and what a career as a lawyer would look like.

Following in his father’s footsteps, William graduated from The University of Texas School of Law, where he found the most enjoyment taking trial advocacy classes. He also served as managing editor of The Review of Litigation.

After graduation, William began his career at Bracewell LLP, where he tried, and won, his first case as lead counsel. Shortly after that trial, William joined Hagans Montgomery Hagans in 2011. Since then, William has been recognized by Thompson Reuters on its Texas Rising Stars list—from 2012-2014—and its Texas Super Lawyers list—from 2014-present. He serves as President of the firm.

William focuses his practice on his clients. Over the years, he has represented community banks, lawyers and law firms, small and large businesses, and families. He enjoys the challenge of both commercial/business dispute cases and serious/catastrophic personal injury cases. And he really enjoys just getting to know different clients from all sorts of different walks of life. William is board certified, by the Texas Board of Legal Specialization, in Personal Injury Trial Law.

William is also actively involved in the community. He has worked with JDRF (formerly the Juvenile Diabetes Research Foundation) since he was diagnosed with Type 1 Diabetes at the age of twelve. In 2010, William was named JDRF’s volunteer of the year. He has twice received the President’s Award for excellence in board leadership and fundraising. He served on the JDRF Houston Gulf Coast Chapter Board of Directors (2013-2019; 2020-2023), on the Advisory Board (2019-2020), and on the Executive Committee (2014-2019; 2020-2023). He currently serves as President of the Houston Community Board of the Southern Texas Chapter as well as on the Executive Council of the Southern Texas Chapter.
