Katie Morgan, M.Ed. – Operations Assistant and Tiny Tech Instructor

  • My personal education and career have been focused on students achieving success in their education. I earned a BA in Psychology at UVa and a MEd in Educational Counseling at VCU. For seven years, I worked as a school counselor with Henrico County schools. I left that position to start a family and to start my own business as an Independent Educational Consultant helping students through the college application process. As my family’s schedule shifted, I started looking for another opportunity to affect the educational development of students, and I found Wray and Tech Em Studios. Wray shares a passion for developing the minds of our youth and has found a unique way to enhance their logic and reasoning abilities in addition to giving them applicable computer skills for the future. As the parent of three kids in preschool, elementary, and middle school, I know how pervasive technology is in our lives, so I appreciate that Tech Em Studios is promoting kids from casual users to masters of that technology.
