Geek Therapy is an approach used by helping professionals which integrates “Geek culture” into their work, often referred to as Therapeutic and Applied Geek and Gaming (TAGG). Examples include psychotherapists using clients' favorite comic books in sessions, social skills group using D&D, recreational therapists using anime, or teachers using video games to teach history.

The term Geek Therapy was coined by Josué Cardona in 2011 and refers to a specific model of integrating Geek culture into practice. In addition to the Geek Therapy model, the organization is dedicated to expanding the TAGG field.

Since 2011, Geek Therapy has evolved from a website celebrating the positive use of Geek culture to a nonprofit organization in 2020.
