Director

LeeAnn Mach

Hello! My name is LeeAnn Mach. I’m currently the Director of Fundraising for YSL in 2025. I am in 12th grade at Allen High School. I am currently in the Allen HS Sinfonia Orchestra and was on the Allen JV Tennis team for 2 years. During my free time, I enjoy playing violin, tennis, and swimming. I was in the swim team from 2nd grade to 8th grade, but I still enjoyed tennis. Being on JV tennis for 2 years was a great experience, until I switched to being in the school orchestra after skipping one year, but I still enjoy playing tennis outside of school with my family and friends. I have the ability to teach the younger ones to play violin, tennis, and swimming. My role for the fundraising department is to maintain funds tracking and reporting monthly to YSL team members.
