COACHING PHILOSOPHY
Coaching at Dordt University is a pleasure and a blessing. I get to walk alongside student-athletes through their highest highs and lowest lows. This is where spiritual and emotional mentoring takes place. My goal is that every woman in the Dordt University women's program will be maximized and equipped with the spiritual, academic, social, and emotional skills to prosper in the workplace while establishing homes built on Jesus Christ.
