Dual vocation

by Nathaniel Miller 

While it is not surprising to see an attorney in a courtroom or a priest in a church, William Hayes is memorable for being at home in both locations. 

Hayes acknowledges that some may think a man of the cloth walking into court may sound like the beginning of a joke, but he is serious about wanting to help those in need of legal assistance. 

Joining the St. Mary’s University School of Law with dreams of becoming a trial lawyer, Hayes, S.J. (J.D. ’22), took every opportunity he could to reach his goal.  

From serving as a clerk for the Texas Attorney General and being a member of the law school’s Advocacy Program on the National Trial Team — winning a national championship in 2022 — Hayes’ resolve to serve others only strengthened with each passing day.

At the same time, he continued to grow in his faith. It wasn’t long before he found himself on a new path: to the priesthood.  

On Aug. 10, 2024, the Denton native took his first vows with the Society of Jesus, also known as the Jesuits. He’s currently studying at Fordham University’s School of Law, pursuing an LL.M. in International Law and Justice in New York.  

“I know people can see me as a Jesuit and think, ‘He’s this holy guy,’ but I’m just a regular person who wants to roll up my sleeves, work and empower others,” Hayes said. “I’m passionate about international law and about helping the marginalized.” 

Life of service

Serving others is not something taken lightly in the Hayes family.   

Growing up, Hayes obtained the rank of Eagle Scout in the Boy Scouts of America, which requires a community service project.  

As a Jesuit, he’s worked with a women’s shelter in Denver; a high school in San Juan, Puerto Rico; with former gang members in Los Angeles; and with day laborers in the Bronx.  

During the summer, he was an activity director for a free camp for inner-city children. 

“In my family, there was always an emphasis on service and helping people,” Hayes said. 

At home in Texas, the Hayes family serves their communities in their own way.  

His father, Richard D. Hayes (J.D. ’78), serves in the Texas House of Representatives for District 57. His sister, Mary Nan Huffman (J.D. ’08), serves on the Houston City Council for District G and is a former assistant district attorney for Montgomery County. His brother, Richard D. Hayes II (J.D. ’13), and brother-in-law, Eli R. Huffman (J.D. ’08), are also graduates of St. Mary’s Law. 

It’s no surprise Hayes and his family have found it easy to give back.  

“That was just the expectation growing up, that you’re going to serve other people,” Hayes said.   

St. Mary’s Lessons

At the School of Law, Hayes knew becoming an attorney would not be easy.   

The National Trial Team was “baptism by fire,” he said, as the program prepares students to become practice-ready attorneys through practice in areas of voir dire, opening statements and examination of witnesses.  

His work in mock trial was not the only area in which he received accolades. Professors noticed his impressive study habits. 

Growing in my relationship with Christ, deepening my prayer life, having an encounter with Him and working with the poor really led me to dive deeper where I wanted to be. I love the idea of being in the courtroom, and then doing things, such as celebrating Mass, preaching and working with people on a spiritual level.”

Professor of Law John Teeter Jr., J.D., said Hayes’ dedication reflects his personal and professional goals. 

“Teaching at St. Mary’s is both an honor and a joy because of wonderful students such as Will,” Teeter said. “I’ll always remember Will’s intellect, work ethic and personal integrity, and I know he will continue to reflect credit upon the School of Law and the  
legal profession.” 

Though separate branches of the Catholic church, the Marianist focus on community appealed to Hayes, helping him find a home among the Jesuits.  

“Growing in my relationship with Christ, deepening my prayer life, having an encounter with Him and working with the poor really led me to dive deeper where I wanted to be,” Hayes said. “I love the idea of being in the courtroom, and then doing things, such as celebrating Mass, preaching and working with people on a spiritual level.”
