What We Publish

We look for psychology and health self-help books that teach readers how to master essential life skills. Mental health professionals who want explanations of psychological techniques and health issues also read our books. Thus, our books must be not only simple and easy to understand but also complete and authoritative. Most of our authors are therapists or other helping professionals.
