Athletic Director – Brian DeHaan, M.Div.


In 2007, Brian DeHaan began directing all aspects of the Maranatha athletic program, and has done so with great effectiveness. His vision for the program is clear and concise and his leadership and pursuit of excellence is motivated by the desire to honor Jesus Christ with the gifts bestowed on this community. DeHaan states, “God is calling us to improve and be the best version of ourselves on a daily basis.”
Today, Maranatha offers 41 teams in 20 sports. On an annual basis, close to 50% of Minutemen varsity teams win league championships, nearly all compete in CIF-­SS playoffs, and approximately 15% of seniors advance to compete in college, which is five times the national average. Under his guidance, Maranatha has earned an impressive 61 league and four CIF-­SS championships, and close to 100 student-athletes have furthered their playing career in college. In the last decade, Maranatha’s athletic ascendance has been clearly evident, but success on the scoreboard is only one measurement. DeHaan’s true definition of success, now and into the future, is evaluated by the impact of Maranatha’s ministry both within the school and beyond.

With collegiate-­level playing experience coupled with 15 years of coaching experience, DeHaan brings a first­-hand and intimate understanding of what it takes to strive for athletic excellence. From 2007-­11, DeHaan served as head coach of the championship-winning Minutemen baseball program including a 2009 CIF­SS championship and back-­to-­back section title appearances. DeHaan holds a bachelor’s degree in psychology from Azusa Pacific University, where he also competed in baseball, as well as a master’s degree in divinity from Fuller Theological Seminary.

Assistant Athletic Director – Eddie Arnett ’96


Eddie Arnett ’96 has served as Maranatha’s Assistant Athletic Director since 2006. Known for his passion for MHS’s mission and his dedication to his alma mater, Arnett is responsible for the athletic department’s operations including inter­departmental and game coordination, facility management, transportation, and summer challenge camps.

In addition to administrative roles which included serving as the Assistant Director of Student Activities, Arnett also brings a perspective of a coach and teacher. Beginning in 1999 and totaling eight seasons, Arnett served the soccer and track programs in the roles of Head and Assistant Coach. Starting in 2004, Arnett held faculty positions in physical education and theology.

Credited for playing a major role in elevating the consistency of many aspects of the Minutemen athletic program, Arnett is grateful for the platform that athletics provides. Arnett reflected, “What’s most important about my role is it allows me to pursue my passion of ministering to students while being a positive example in their lives.”

Athletic Director Brian DeHaan comments, “Eddie’s professional and personal approach to building community is beyond valuable. He has a unique ability to create and build long-­lasting relationships with students, student­-athletes, coaches, teachers, staff, families, and alumni. The Maranatha community is blessed to have him, and he is a wonderful example of the ‘glue’ that every great culture has.”

Arnett is a graduate of Azusa Pacific University where he earned his bachelor’s degree in liberal studies with an emphasis in physical education.

Athletic Trainer – Kelly Wierema, M.A., A.T.C.


Since 2013, Kelly Wierema, M.A., A.T.C., has held the role of Athletic Trainer at Maranatha High School. Wierema is responsible for overseeing the physical well­-being of Minutemen student-­athletes and providing high-level care which includes injury prevention, clinical evaluation and diagnosis, immediate and emergency care, treatment, and rehabilitation.

Known for her expertise in the field of athletic training and her relational approach, Athletic Director Brian DeHaan considers Wierema another invaluable member of the athletic department. “There is nothing more important than the health and well-­being of our students. I am thrilled to have a professional like Kelly on the team. Our entire athletic program benefits from her leadership on a daily basis,” said DeHaan.

The feeling is mutual. Wierema feels blessed to work at a place like MHS. She comments, “It’s unique to work at Maranatha because the kids maintain a healthy balance. On and off the field, Maranatha student­-athletes compete at a high level while displaying great character.”

Wierema’s athletic training profession has opened doors for her to travel the world using her gifts to positively impact others. During her career, the former collegiate volleyball player has provided health services to athletes in Germany and Australia in sports such as rugby and soccer. Domestically, Wierema has served at athletic competitions for U.S.A. Lacrosse and at California State University, Chico. Her experience spans across a wide range of sports from football, track and field, and men’s basketball, to cross country and women’s softball.

In addition to her professional responsibilities, Wierema has been an active volunteer in her community. In 2014, Wierema led Maranatha students on a mission’s trip to New Orleans where her team built homes for families affected by Hurricane Katrina. The Anaheim Ducks, the Mount San Antonio College relays, Chapman University, and high schools across Orange County have also benefitted from Wierema’s giving heart.

The Northern California native holds a bachelor’s degree in athletic training from Chapman University, and a master’s degree in kinesiology from California State University, Chico. Wierema also holds certifications from the National Athletics Trainers’ Association and the American Red Cross.
