IB PYP Coordinator & Instructional Coach
Being at Preston Hollow IB World School has been my second home for a number of years. I began here as a classroom teacher teaching language arts/reading to 3rd, 4th, and 5th grade scholars. Now it’s my pleasure to have and be committed to the role and responsibilities of Reading Curriculum Instructional Coach. Each day my main focuses are to examine practices in the classroom in a reflective way, observe instruction and provide constructive feedback, support, model, and facilitate teachers in their classrooms during professional development times and common planning times.
