The coaching staff have always been the teachers leading me on the path to success through this sport and their dedication to their athletes is unmatched.
The Philosophy of "mens sana in corpore sano" -- "a healthy mind in a healthy body"-- has long been a part of Prep education. Preppers strive for excellence in athletics as well as academics. In striving for success, the members of the Prep coaching staff endeavor to instill the qualities of leadership, loyalty, and sportsmanship. The student athlete learns to cope with winning and losing; to be humble in victory, proud in defeat.

Princehorn Named New Lacrosse Coach at St. Joseph’s Prep
Arrives After Successful Stints at Souderton and Lansdale Catholic

   PHILADELPHIA -- St. Joseph’s Prep announces that Mark Princehorn has been named the school’s new head lacrosse coach. Princehorn comes to the Prep after successful stints at Souderton High School, where he built a strong program that competes in the Suburban One Playoffs and districts each year, and Lansdale Catholic, where they were a perennial state playoff team. 

   “I have admired Mark’s coaching for years as my teams have competed against his,” says Athletic Director Dan DiBerardinis. “He has the ability to help his team win games because of his coaching. However, most importantly for a coaching job at the Prep, he understands the value of helping his student-athletes become the best versions of themselves, on and off the field. When we were able to hire someone of his character combined with his knowledge of lacrosse, and his work ethic, I was excited.”

   Princehorn, a native of Central Ohio, is thrilled to lead lacrosse at St. Joseph’s Prep. “For me, the Prep was such an obvious choice,” he says. “The Prep’s motto of being a Man For and With Others is the foundation of my coaching philosophy. I pour everything into helping my players in their lives. I want them to positively impact others in their life. That is the foundation that I want to instill into our program at the Prep.”

   He continues, saying, “I’m a lacrosse coach but most importantly I mold young men, helping my players get the most out of themselves and putting them into positions to succeed. I am so happy to do that at a place as prestigious as the Prep. These aren’t empty words. I will back up what I say.”

   While Princehorn was happy at LC, he couldn’t pass up the opportunity to coach at the Prep. “It’s the Prep, who wouldn’t want this job?” he says. “You have the chance to set your goals at the highest level and know that they are attainable. I am so thrilled to be able to coach the kind of student-athlete that the Prep attracts. I feel that the Prep is at the pinnacle of the game in this area, one of the better teams in the state every year. People of high caliber who also compete at a high caliber. Young men who will make a positive impact in the community.” 

   Princehorn had a very successful high school career, earning all-league, all-state, and all-Midwest. That enabled him to continue to play in college. Though he had several Division 1 offers, his family situation was such that he wanted to stay close to home and played at Ohio Wesleyan, where they won two conference championships and played in four NCAA tournaments.

   He started coaching at the club level while still in college and “loved immersing myself in that world.” He moved to the city in 2011 to work in finance but missed coaching. Thanks to the patience of his boss (Steve Harris, a 1999 Prep grad), he was able to do both. That led to an opportunity to coach at Souderton High School, where he became the program’s all-time winningest coach, with many of his players going on to play in college and beyond (even going professional as he coached Jake Phaup who is now playing in the Premier Lacrosse League for the Atlas). While at Souderton, the program secured its first playoff berth and victory and it is now one of the best programs in the area.

   From there, he moved to Lansdale Catholic, where he also served as the Athletic Director and taught history classes. He also built LC’s program into one of the better ones in the Catholic League: the Crusaders won 30 games in two years, won back-to-back district titles, and twice advanced to the PCL semifinals. In addition, many of his players were able to achieve personal success, with all-Catholics, four players recruited to play in college, and one named area player of the year.

   In addition to his Bachelor’s degree from Ohio Wesleyan, he holds a Master’s in Coaching and Athletic Administration from Concordia University in Irvine. He and his wife, Lindsay, have one son Cole. Cole was born with Biliary Atresia, a condition in infants in which the bile ducts outside and inside the liver are scarred and blocked, and last week received a liver transplant at Children’s Hospital of Philadelphia. Princehorn says that “Cole is my hero. He’s had a tough road but he has taken every challenge. I am so proud of him. He is such a blessing. I am so glad his health is turning around and he is progressing in the right direction.”

   The Princehorns have started an organization called Cole’s Goals to help fund the liver research foundation at CHOP and provide help and positivity for others. The first benefit game at Lansdale Catholic raised more than $7,000 and he hopes to have a similar impact at the Prep. “Family, faith, academics, work ethic are things that I try to instill in myself, my family, and my players,” he says. “I am so excited for the opportunity to coach at the Prep and bring these principles to our program.”
