She completed her Bachelors of Science degree in Psychology at San Jose State University in December of 2018. She graduated a semester early to push her dreams of becoming an Occupational Therapist closer.

From there she continued the route of care to be a caregiver at a senior living memory care facility, then a physical therapy aide. Edellene officially started her journey as an RBT in the summer of 2018 and concurrently interned for the occupational therapy program at the same company. She is excited to see her development in this field and apply it in her future as a possible occupational therapist.
