For the past 95 years, the Texas Cavaliers have selected one of their members to serve as King Antonio to reign over the San Antonio celebration known as Fiesta.  In keeping with this tradition, the Cavaliers selected King William neighbor Dr. Michael “Mike” Casillas as King Antonio XCV.  Mike’s mission as King Antonio has been to spread the message that an act of kindness is the greatest gift you can give or receive.  Kindness really does start with one — one person, one act, one place, one city, one county, and one movement with one goal in mind: To make our world a kinder place one act at a time.  And with Mike’s mission in mind, every single one of us can play a part in this by being good to another person. That is what makes a difference in our world.  He visited many schools and numerous charity events, plus the multitude of official Fiesta events during his 2017 reign.  

Mike’s San Antonio roots date back eight generations to a member of Governor Martin de Alcorn’s expedition, which founded San Antonio on May 5, 1718.  In addition, he has multiple Canary Islander ancestors who established the first municipal government in San Antonio in 1731.  Mike’s proud heritage and his commitment to and love for his city were clear when he served as the first Hispanic King Antonio. 

Mike was born in San Antonio to Albert and Margaret Casillas.  He graduated from Central Catholic High School, attended UTSA, and received a Doctor of Dental Surgery Degree from the University of Texas Health Science Center at San Antonio.  Mike became a partner in San Antonio Surgical Arts, where he has been practicing oral surgery for 22 years.  Mike married his high school sweetheart, Jessica Treviño; the couple has two sons, Julian and Matthew.  Jessica grew up in the King William neighborhood as part of the El Mirador Treviño family.  

Elected to the organization in 2003, Mike has performed multiple roles: served as a board member of the Texas Cavaliers Charitable Foundation; coordinated the activities of the River Parade as Parade Marshal in 2013; led the 600-strong Texas Cavalier membership as Commander, while serving on the Executive Committee of the Fiesta Commission in 2015-2016.  His commitment and successful performance in these key roles ultimately led to his election as King Antonio XCV. 

Thanks, Mike, for serving our city so well!  Viva King Antonio!
