  • Viola Lizarraga

    Branch Manager
    Viola got into the Healthcare field at a young age while she was still in high school.  She started by working with children with developmental disabilities.  She always imagined the children did not have a disability, but a super power that made them special. That is when she found out her dream was to have a job that always puts others first and help them in every way possible.  After high school, Viola started working with a company that worked with different ages of people with super powers in a group home setting.  In 2017, Viola joined the BrightStar family as a caregiver.  She loved having the opportunity to work with individuals one on one in their home helping them get to and use their full potential. In March 2018, the office noticed how much compassion and empathy Viola had for her clients and asked her to join us full time in the office as our Scheduling Coordinator.  She gladly accepted the position, and she now loves that she has the opportunity to help all of our clients instead of just one. She recently had the oppirtunity to further her ability to help not only our clients but to also help all of our staff by accepting the postions as Branch Manager  in October 2021.
