Empowering High Achievers

About Our Founder

About Sarah McKinzie (M.S.)

I’m Sarah E. McKinzie, M.S., a cognitive psychology professional specializing in human cognitive neuroscience and advanced statistical analysis. With 20+ years of experience as an educator, researcher, instructional designer, and tutor, I help learners build real skills through evidence-based instruction, clear explanations, and practical strategies that stick.

My background includes graduate-level work in learning, memory, and cognitive development, including supervised research in an EEG lab focused on brain patterns in children. I’ve taught college-level Introductory Statistics and Psychological Research Methods, supported adult learners preparing for GED/HiSET exams, and created curriculum for both in-person and virtual learning environments.

Today, I combine research-driven methods with a student-centered approach—whether I’m tutoring, building learning resources, or evaluating AI model outputs for accuracy and quality. My goal is simple: make complex material understandable, build confidence, and help students perform at their highest level.
