Mary Bosker, PhD

Dr. Bosker’s Mission:

– to restore hope to those who have lost hope

– to help people improve their sense of self-worth, value, and purpose in life

– to facilitate healing, recovery, and personal growth in a safe harbor of compassion and understanding

Dr. Mary Bosker is the first in her family to be born in the U.S. and also the first to earn a doctoral degree. She earned her Bachelors degree from Hope College in 1993. She majored in psychology, but also studied various languages and religions, and lived overseas for half a year. In doing so, she gained a deeper understanding of how people from different cultural, ethnic, and religious backgrounds approach life. She subsequently worked at a shelter for homeless women before starting her graduate studies at Southern Illinois University at Carbondale (SIUC).

Dr. Bosker completed her Master of Arts and Ph.D. in Counseling Psychology at SIUC. She then moved to southern California to complete her internship at the University of California San Diego (UCSD). She subsequently completed her postdoctoral fellowship at Aurora Behavioral Healthcare in San Diego. Dr. Bosker has been continuously licensed as a psychologist in the State of California since 2007. She has been with Lifestance Health since 2022.

Prior to joining Lifestance Health, Dr. Bosker worked in a variety of clinical settings, including university counseling centers, crisis houses (short-term residential psychiatric facilities), psychiatric hospitals, residential rehabilitation facilities (for substance abuse), a counseling center for military personnel and their family members, and a military outpatient mental health clinic.

Altogether, Dr. Bosker has been working in the mental health field for almost 30 years. She has successfully helped many, many individuals, ranging in ages and life stages from kindergarten to well past retirement. She has also worked with numerous couples and families. She is dedicated to her mission.
