Creating Meaningful Impact

The DTRI is committed to raising awareness of dyscalculia: the math learning disability.

Dyscalculia causes people to lose math information over time, and leads to school struggles, limited college and career choices, and loss of earnings and self-esteem.

All of this is unnecessary, because supporting people with dyscalculia is easy when educators and employers are aware of the learning difference.

Join us and change the math experience for students and adults with dyscalculia.


The DTRI is women-led and math-focused.

Our board of directors includes teachers, psychologists, and parents who understand dyscalculia.

Our leadership team is committed expanding awareness and research about this neurodiverse Specific Learning Disorder.
