We provide a variety of services including psychological evaluation of individuals as well as program evaluation and training. Dedication to evidence based practices is what sets us apart from our competitors.

Jewell Psychological Services is dedicated to the creation, research, and dissemination of evidence-based practices in psychological evaluation and treatment.

What does this mean exactly? It means that we engage in evaluation and treatment practices that have been shown to be most effective through well-designed and controlled scientific research studies.

Why does this matter? Unfortunately, there are many individuals and agencies that provide psychological services that are not evidence-based. This means that either there is no research to show that the practice is effective, research clearly shows that the practice is ineffective, or worst of all research shows that the practice may actually be harmful.
