JuliAnna considers it one of her greatest joys in life to have landed at The Arbor and to serve such a dedicated community of Board members, incredible staff, and the most amazing students and parents around. When she’s not at her Arbor home, JuliAnna can be found at her house home-schooling and chasing her three young kids around while drinking copious amounts of caffeine. She loves the outdoors and the Texas Hill Country is her happy place.

Tricia Bingham

Director of Education

As Director of Education, she is now responsible for leading the teaching staff and implementing best practices in curriculum and education programs at The Arbor. Tricia has her Master’s in Curriculum and Instruction and has 17 years of education experience with children with special needs – one of her favorite parts about working at The Arbor is getting to know each student and their families because this has truly become her second family! Tricia is also certified in assistive technology for children with special needs, and considers it such a privilege to get to support our amazing teachers in the work that they do in the classrooms! When she’s not at the Arbor, you can find her going on “adventures” (like taking a trip to Lowe’s) with her husband and  two little boys or going on a Saturday morning run that somehow always ends at the breakfast taco shop!

For Ms. Aqeela, this is not “just a job,” it is something that she is called to do! With her unwavering patience and compassion, she feels that she was created to help those who need it most. In her own words, “When I see the light in the eyes of my students and their parents, I feel that I was able to make a difference in their life and that gives me a feeling of fulfillment every day.”
