The gratitude the participants express gives me the strength to come to work every day. They enrich me with their history, backgrounds and cultures and is my favorite part about working with elders. PACE provides me with a unique environment to be creative with problem-solving skills to address the complex issues and barriers that seniors face on a regular basis.
I was raised on a Marine military base in San Diego and moved to Northern California in my mid-20s after studying abroad. I earned my Registered Dietitian’s license in 2020, a month after joining Center for Elders’ Independence.
After PACE Concord opened, I stepped into a leadership role becoming the Day Center Supervisor. Now at Tri-Valley, I am thrilled to be the Center Manager.
I speak English and very limited Spanish.
For my time outside of work, my fiancé and I enjoy cooking all kinds of foods as we are both dietitians and big-time foodies. We also stay active by hiking the many trails here in the Bay Area and have fun with our two cats, Tonks and Diggory.
