The Arnold E. Holtberg Athletic Leadership Award

The Arnold E. Holtberg Athletic Leadership Award is presented to a senior athlete who embodies the ideals of character and leadership in every facet of his participation on the playing fields, in the locker room, and around campus. Never losing sight of the virtues of sportsmanship and honor, this young man has upheld the school’s highest traditions in his quest for excellence from himself, his teammates, and his peers.

Leo Ohannessian ’21

The St. Mark’s swimming and water polo teams consist of an exceptional group of student-athletes who have built a strong culture based on honor, brotherhood, sportsmanship, accountability, and a commitment to excellence. One of the cornerstones for both of these teams is a young man who has served as the Team Captain for both swimming and water polo and has demonstrated outstanding character and leadership throughout his time at our School. Leo Ohannessian is an excellent student-athlete who has consistently pushed those around him to be better, and his relentless work ethic, dedication, and character have been a driving force behind the extraordinary success of our aquatics programs in recent years.
 
Leo is a fierce competitor with the heart of a champion, and his incredible passion for both swimming and water polo has been infectious to his teammates. His tremendous focus and intensity often set the tone for practices and competitions, and it is obvious how well respected he is by his peers. His many individual accomplishments and achievements at St. Mark’s are a reflection of his steadfast dedication to both sports, while the consistent success of these championship teams is a testament to his strong leadership.
 
Leo excels in both the pool and the classroom and is truly someone that the younger boys can look up to and say, “I want to be like him”. He represents all of the qualities our athletic program strives to instill in boys, and is a textbook example of how to do things the right way. He has certainly left his mark on St. Mark’s, and we are excited for the bright future ahead of him as he continues his journey as a water polo student-athlete at UC Santa Barbara next year.
 
Coach Trent Calder shares the strong impression that Leo has made on him in just a year’s time:
 
“Leo is a leader by nature and a young man who holds himself and his teammates to the highest standard.  He leads by example through his work ethic, discipline, and competitiveness, and is a true role model of what it means to be a St. Mark’s Swimming and Water Polo Student-Athlete.  He was top producer for the swimming team at SPC, a multisport athlete who is now an 8-year letter winner and 4-time team MVP. He has been an outstanding leader as a water polo Team Captain and leads through example with hard work, dedication, a competitive nature, and is an inspiration to his teammates. This student-athlete also has multiple state and national honors to his name and is a dual-sport athlete.”
