Mens Coaching Staff

Head Coach

A business owner, a father, a husband, a musician and a coach. While I have played many sports in a competitive nature in high school, club or collegiately from baseball, football, track and field, wrestling and water polo, my favorite sport is lacrosse and second is wrestling.

I started my lacrosse career in 1998 during my senior year of high school and the next 2 years developing my skills before, joining the Oregon state University men’s lacrosse team in 2000. I played Defensive pole and was a PNCLL all-star during my 3 rd and 4 th year of playing at OSU. I graduated with a degree in Geology in 2004 before pursuing a career in construction. After playing some adult league for a couple of years the love of lacrosse kept tugging on me to get more involved. I began my coaching career in 2006 as the head coach of century high school (2 time coach of the year league honors) before making coaching stops at Clackamas, west Albany, La Salle, Wilsonville (1 time assistant coach of the year league honors) and now I am starting my 17th year of coaching as the Head coach of Clackamas/Nelson lax.

My passion for lacrosse has led me to connect with young men and woman to be a positive role model and to share in the development of their skills both on and off the field. There are so many things to learn from sports that are applicable throughout life and I am glad I get the opportunity to help share and show those to young athletes like my wrestling coach did for me in high school.

My wife Emily has been such a great support throughout my coaching career and I always appreciate her sacrifice every year to take care of our 3 boys so I can pursue my passion. When I am not coaching I am pursuing my music, traveling, building and the many other hobbies (or as my wife says my need for stuff).

Offensive Coordinator, Keith Sheehan

Keith Sheehan, husband, dad, coach.   I love the game of the lacrosse, its history, creativity and its potential growth.  I am proud to have been introduced to the game in the place of its origin and excited to be coaching in a place where it's future holds so much opportunity.

 I believe strongly that the lessons learned from playing sports have more to do with how to become a good teammate, overcoming challenges, learning the benefits of physical activity on the mind and body, learning to be a good communicator, a good person and understanding what you are capable of and less to do with goals scored, playing time and wins and losses.

 I have had the opportunity to coach the game for the last 7 years and the great fortune of playing the game most of my life

JV Head Coach, Zac Foteff

I first started playing in 2009 for Clackamas Youth Lacrosse and stayed with the program until 2014 when I went to play for La Salle. During middle and high school I played club Lacrosse year round for a variety of different club teams in Oregon including: Rhino, Lax NW, Valhalla, and Madlax. In my time at La Salle, the team traveled to play in the Cascade Cup finals against Hood River. I received multiple all-conference awards as well as academic performance awards.

In 2018, I went to Gonzaga University had the opportunity to play for the Gonzaga Mens Lacrosse team. We traveled to play teams in Montana, Idaho, and around Washington, and we made it to the first round of playoffs in the MCLA. Unfortunately, COVID-19 disrupted the 2019-2020 schedule and I didn't get the opportunity to play for the Gonzaga team again until my senior year. I graduated from Gonzaga with a BS in Computer Science and am excited to now be coaching alongside my old high school coach.

I'm excited to work with every player to develop their game IQ, their confidence, and their skills over the course of this next year, and I'm especially excited to be a part of building the Clackamas Lacrosse program's sense of community.

JV Assistant Coach, Vince Christenson

My name is Vince Christenson. I'm born and raised in Portland, and started playing lacrosse in 2012 for the Clackamas youth program. Ever since I started playing lacrosse, I couldn't put my stick down. I played for Clackamas until I graduated in 2019. Then, I played lacrosse for 4 years at the University of Oregon, where I received multiple all-conference honors. 


I am thrilled to be apart of the Clackamas coaching staff. My goal is to spread the love for lacrosse in my hometown while strengthening our highschool players. I am very excited to see our team and program improve every year, as we build something special in our growing city.
