      Katie Falwell, Ph.D., BCBA-D

      Chief Executive Officer/Founder

      I am a Florida licensed psychologist specializing in child development. I’m also a licensed clinical psychologist in my home state of Virginia where I provide consultation to hospitals and school systems. I completed my pre-doctoral training at Johns Hopkins School of Medicine and postdoctoral residency at the University of Florida. I became a member of the faculty at University of Florida in 2006. Shortly after moving to Gainesville, I became aware that North Florida had few resources to meet child development needs. That led me to open Keystone Behavioral Pediatrics in 2008 and then to develop a premier early learning center, KCDC, in 2013.

      We have discovered through our collaborative work in integrated healthcare and premier education that all children benefit from individualized attention focused on their strengths. As a result, with the beginning of the 2017-18 school year, we are retiring KCDC and opening two new schools. Collage Day School and Mosaic Day School allow us to serve all children and help them achieve their greatest success. Collage provides an academically challenging environment based on the best educational research available, while Mosaic offers an educationally appropriate curriculum for children with special needs. Both programs use research-based practices, techniques and pedagogy to bring out the best in children.

      I am passionate about my work helping children as a clinician, educator, consultant and researcher. I live in Ponte Vedra and enjoy embracing all that coastal living has to offer, along with spending time with my family – my infant and toddler sons and teenage daughter.

      Ashley Miller, BA
      Elementary School Teacher

      Growing up with a sister with special abilities allowed me to see the world differently. And I’ve been able to learn and grow alongside her. I graduated from UNF with a Bachelor degree in Communications and a Bachelor degree in English with a minor in Professional Education. I have several professional developments under my belt that have taught me how to use movement during the day to keep students engaged, as well as how to accommodate their sensory needs. After being a middle school classroom assistant in a private school for 2 years, I decided to get my certification in Special Education for K-12. I’m excited to be taking on the challenge as a Kindergarten Teacher this year! I look forward to getting to know the students and families and hope to continue to learn from my students as much as they learn from me.
