Joshua also has specialized training in several types of evidence-based therapy (e.g., ACT, CBT, CPT for PTSD, and full-model DBT). Combined, these forms of therapy support patients with issues in impulse control, parenting skills, anger management, grief, health behaviors, self-harm, sexual/gender issues, emotion regulation and coping skills acquisition.
