I have worked in education since graduating from college in 1997, starting as a substitute teacher, working up to a teaching coach for Merced City School District. My classroom and now STEAM Center is well-managed with high expectations for all students to learn in a diverse learning environment. I have excellent communication skills and a passion for high-quality education. I am active in education outside of the classroom as I have been an active member of the California Association of Directors of Activities for the past 15 years. With CADA, I have served on the Area C Council for nine years and earned my Master Activity Advisor certificate. I have also taken my ASB officers to CADA/CASL Leadership Camp at UCSB for the past 12 summers and worked as a camp council leader for the past 7 summers.
