Head Coach | Ryan MacDonald

Coach Ryan “Mac” MacDonald has a long history with the Colorado State Rams from 2005 – Present. He was a lethal offensive midfielder during his playing days and demanded the attention of opposing teams’ best defenders. Coach Mac was a natural leader who brought passion to the field and the best out of his teammates. His combination of skill and leadership helped the Rams win the 2006 MCLA National Championship. Individually, he was recognized as a Team Offensive MVP, RMLC 1st Team Midfielder, and was named to the MCLA’s All-America 2nd Team.

As a coach, Coach Mac is forever hardworking and will never give up – much like the way he played. He will hold you accountable and help you reach your fullest potential. Coach Mac holds the idea of “Family” at a premium, and he believes that a strong team culture is just as important as physical ability. He loves this game and puts his heart and soul into everyday. Coach Mac will do everything in his power to help each athlete become successful as a player and a student.

Defensive Coordinator | Patrick "Sully" Sullivan

Patrick "Sully" Sullivan was an assistant coach for the Rams under Alex Smith during the 2014 and 2015 seasons, and after a successful two year stint at Thompson Valley High School, where he was awarded Assistant Coach of the Year in the Pikes Peak Conference, Coach Sully is back head manning the Rams Defense.  In 2014 and 2015 Coach Sully’s unit was awarded four 1st Team All American Defensemen spots, featured a tandem of two outstanding goalies and a slew of talented D-Mids.  Sully looks forward to re-establishing the gritty, punishing style of defense that made CSU great over the years.

Patrick grew up in Littleton, CO and is a product of Heritage High School.  Coach Sully wore the horns for four years as a member of the CSU mens lax program and being a four year starter, enjoyed a very successful college lacrosse career.  On the field Sully was known for his outstanding footwork and fundamentals, as well as earning All Conference honors twice and twice named to the MCLA All America team.


Off the field Sully was a natural leader and named Team Captain as a Senior.  On its way to the programs fifth National Championship, Sully anchored a Historic Rams defense that gave up the fewest GAA in the History of the MCLA tournament.  In 2013 Patrick was named team captain and helped lead the Rams to their first undefeated season, Back-to-Back National Championships and another historic defensive performance through the MCLA national tournament. The following year was Sully’s first season coaching the Rams.  His passion for CSU Lacrosse is unmatched and we are extremely excited to have him as part of the family again.

Offensive Coordinator | Jake Flax

Jake Flax wore Gold horns from 2007-2011 and joins a coaching staff of fellow CSU Lacrosse Alumni. After ‘hanging-up-his-cleats’ in 2011 Jake returned to his hometown of Steamboat Springs, CO and took on a heavy load of responsibility with all of Steamboat lacrosse. He and his twin brother, Andy, spent the last 6 years co-operating Steamboat’s youth lacrosse program and helping coach Steamboat Springs High Schools Varsity team in the Spring. Coach Flax’s offensive creativity will bring a breath of fresh air to the Ram’s Offense.

Jake joined the Rams as a red-shirt freshman in 2007 and left the Rams in 2011 as a Senior Captain and Team President. Jake was a shifty, fundamentally sound attackman during his time in the green and gold. But his greatest impact to the program took place off the field. Jake was the best teammate any player could ask for, he always had the Family’s best interest in mind and was a shining example of what it takes to BE A RAM. Coach Flax doesn’t have the hardware to wear on his finger but the success CSU had following 2011 was greatly impacted by coach Flax and the rest of his senior class.

He is proud to have played for legendary CSU Coaches Flip Naumburg and Alex Smith. Coach Flax will join the coaching staff as the Offensive Coordinator for the 2018 season.
