Executive Functioning Coach

Amy Rose

I have been working as a private ADHD and Academic Coach for the past six years, helping students develop the executive functioning, organizational, and study skills they need to thrive both academically and personally. For the past four years, I have also served as an Academic Coach at Cheder Lubavitch Girls Elementary School and, more recently, at the Boys School, in addition to teaching as a Math Resource instructor at Yeshivas Tiferes Tzvi (YTT).

I am passionate about empowering students to recognize their strengths, build confidence, and develop practical strategies that lead to lasting success in the classroom and beyond. I believe that every child can succeed when given the right tools, encouragement, and support.

A native Chicagoan, I live in West Rogers Park with my family and am the proud mother of six children.
