Marksman Wins NCAA Title
On May 25, Ian Mize ’22 lifted the 2026 NCAA Division I Men’s Lacrosse National Championship trophy alongside his Princeton Tigers teammates. Mize, a senior midfielder, helped the top-seeded Tigers complete an incredible postseason run that ended with a 16-9 victory over Notre Dame at the championship game in Charlottesville, Virginia. Mize graduated from Princeton the day after the National Championship and has started his career in finance, living and working in New York City.
At St. Mark’s, Mize was a four-year starter on the varsity lacrosse team, served as team captain, and helped lead the team to the state championship final four in 2022. The Mize family, including Ian's father Roby, Jr. ’83 and brothers Roby III ’16 and Garrett ’18, has a long and meaningful legacy in athletics at St. Mark’s. The Roby Mize Training Room is named for Ian's grandfather, Dr. Roby Mize, an emeritus Trustee who also served as the consulting physician for generations of Marksmen athletes.
