My junior year I tore my labrum during preseason and had to have shoulder surgery. It ended my junior season and started over a year of recovery, which was majorly delayed because of the pandemic. It was easy to look at it like a loss, but I committed myself to my recovery and in my senior year, at our season opener, I scored and came back like nothing had happened. Of course, I'm proud of the conference championships we've won and the NCAA appearances we've made, but I'm most proud of myself for my full recovery and the fact that I proved to myself that I could come back even stronger.

"My proudest hockey moment would definitely be my game against East Stroudsburg when I played at Millersville. It was an overtime win. Defensively it was the toughest game of hockey I ever played both physically and mentally. We had multiple players injured. It was the best game of hockey I had ever played and a win I will always remember.
This moment ties in with my coaching philosophy. I remind our players constantly to "control the controllables". We cannot change how physical a team is, how the officials manage a game, the weather or even how their teammates are playing. I am all for accountability, but I also believe our players should be focused on themselves and what they can do to better their play rather than what others should do for them. If everyone does their job, we will be successful. I am a very competitive person and want to win. However, I want our players to take their determination, hustle and motivation and apply it in the real world. That is my ultimate goal as a coach is to build long lasting relationships with these players and help them build their character and skill all while enjoying the game. I want them to carry these skills beyond the field hockey field/court. I try to build relationships with these players in order to build trust and keep open communication. I am here for them on and off the field. I believe in them and know what each and everyone of my players is capable of. My expectations are high, but manageable as to what they are capable of. I truly love this sport, the TCOYO staff and our talented players. "
