Graduate Assistants

Angela Kim

Angela is an OTD student who was born in South Korea. She moved to California when she was 8 years old and graduated from UCLA in 2020 with a degree in psychobiology. Angela became interested in caring for older adults as her grandparents became older.

Angela hopes that her training will help older adults have a move comfortable home environment in the near future.

Growing up, Noah spent a lot of time with his grandparents and helped them around their home.
