Her personal experience with an eating disorder and subsequent recovery motivated Diahann to pursue a Master’s degree in Clinical Psychology from Antioch University, Los Angeles. Her career as a Licensed Marriage and Family Therapist has led to clinical work with a variety of populations and needs.
