Yvonne Caro

Administrative Assistant

I was born and raised in El Centro, CA, but I spent the last eight years living in Sacramento before moving to San Diego in May of 2024. Fitness and healthy living are a big part of my lifestyle—I love staying active and making wellness a priority. I’m also a huge sports fan, both as a spectator and a player. Volleyball is my favorite sport to play; I’ve been playing indoor volleyball for years, and since moving to San Diego, I’ve started playing beach volleyball as well. Outside of sports and fitness, my biggest joy in life is my three children—my 15-year-old son, my 11-year-old son, and my 10-year-old daughter. Spending time with them means everything to me. Another one of my favorite hobbies is shopping, especially when I get to do it with my sister. After being apart for the past eight years, I really cherish the time we get to spend together. I also have a strong interest in astrology and enjoy learning more about it whenever I can.
