Lisa Monarrez

Administrative Assistant

Lisa Monarrez graduated from Cal State LA with a bachelor's in Nutritional Science. Previously, she worked at an eating disorder clinic in Santa Monica as a diet technician and fell in love with this field of work. Her passion is helping people and encouraging them to see their true potential in life. One of her favorite quotes is "For what it's worth... it's never too late, or in my case too early, to be whoever you want to be. There's no time limit. Start whenever you want. You can change or stay the same. There are no rules to this thing. We can make the best or the worst of it. I hope you make the best of it. I hope you see things that startle you. I hope you feel things you never felt before. I hope you meet people who have a different point of view. I hope you live a life you're proud of, and if you're not, I hope you have the courage to start all over again." - F. Scott Fitzgerald.
