Dr. Lydia Chun was born and raised up in Seoul, South Korea, and is bilingual in Korean and English. She has been trained in diverse theoretical orientations and treatment modalities including psychodynamic psychotherapy, cognitive-behavioral therapy, couple’s therapy, children, adolescent, and family therapy. She has her own private practice in Fullerton CA and works with individuals, seniors, couples, adolescents, and children on a wide variety of issues including anxiety, depression, relationship, family problems, and ethnic minority issues. She is very passionate about destigmatizing mental health in the community and has been actively promoting mental health in the Korean American community.

Dr. Lydia Chun’s passion is to help students to grow deeper in their relationship with themselves, each other, and God as they work through the challenges they face. She incorporates faith-based and Biblical principles in her work when appropriate. She desires to help students to become the people God created them to be by working through patterns that prevent them from growing and reaching their full potential. She has been married for more than 34 years and has two adult children.
