Hello, my name is Angela. I am a Service Partner, Office assistant, and Company Marketer. I have been blessed to work here part-time for many years. I have an associate degree in art and am currently working on my bachelors. Before joining the team full-time I worked retail management and as a preschool teacher. I left the preschool to join the family business and have loved my decision.
