If you're lucky, you might catch a glimpse of Charina in the clinic as she bustles in and out doing a lot of everything behind the scenes and while taking care of the Willis kiddos.
She has 8 years of office and billing management, but particularly loves the patients. The value of making someone's life better with greater ease and happiness makes it all worth while.

Charina loves being outside, a clean house, donuts, and of course, her family.
