Alumni Leadership Speaker Series 2025


The Alumni Association welcomed three guest speakers who have been many things throughout their careers – Grizzlies, Longhorns, Cowboys – but they will always be Lions at heart. The 2025 Alumni Leadership Speaker Series featured current and former professional athletes and coaches who discussed the lasting impact of St. Mark’s, sports, and the qualities that form a good man.  
 
The panel included: 
  • Sam Acho ’07, ESPN analyst and a former NFL linebacker 
  • Taylor Jenkins ’03, NBA Head Coach of the Memphis Grizzlies 
  • Sean Lissemore, St. Mark’s Athletic Director and a former NFL defensive end 
The panel was moderated by Scott Jolly, Assistant Headmaster for External Affairs and a former St. Mark’s basketball coach – who also coached Acho and Jenkins as students.
