Sherry Nasseri, Secretary

Sherry has built her career helping people to navigate the mental health challenges that impact their quality of life. She has connected physical and behavioral health to form a holistic view of what a patient is experiencing to assist them in a more fulfilling and balanced life.
After successfully completing her graduate studies and training, she assumed a leadership position at HealthCare Partners (now known as Optum). Her role involved pioneering a program within hospital settings, focusing on patients aged 65 and older who were grappling with high-risk chronic conditions, often resulting in undiagnosed depression. The program’s groundbreaking work drove the field of medicine to begin recognizing the connection between physical conditions and mental health.
One of the major initiatives Sherry spearheaded at HCP was a program that studied how underserved populations and cultures experienced and coped with high-risk medical issues and end-of-life conversations. The team created innovative methods for delivering culturally-sensitive, critical medical information to elderly, and poverty-stricken patients. Their success enabled them to implement partnerships in the program with leading Los Angeles hospitals including UCLA, Providence Dignity Health, and Cedars-Sinai. This eventually led to her work as Director of Palliative Care at Health Essentials Medical Group.
Today, Sherry works in private practice with clients as they navigate challenges with aging, career, marriage, illness, and family. She lectures at various universities, such as USC and UCLA. She and her husband, Pardis, are proud parents of son, Kasra ’35, and daughter, Nika.
