I have had the immense privilege and pleasure of serving UCLA and its athletic department for the past 36 years. I have enjoyed every moment of this journey, so it is bittersweet to announce that I will retire as the head coach of the UCLA Gymnastics team following the 2019 season. I have always thought of life as a grand adventure, and since conquering breast cancer, I have been motivated to delve deeper into the many different areas of life that inspire me. I will greatly miss all of the wonderful people that make up UCLA Athletics and, most importantly, the daily interaction with our student-athletes, coaches and staff. However, I will forever be our most ardent supporter and look forward to continuing the dance in a different role but always as a proud UCLA Bruin.
