Perle Treguier in Chula Vista's Third Avenue Village offers psychological services from a Suite B8 office at 310 Third Avenue, one of the walkable downtown corridor's established behavioral-health locations. Assessment and treatment planning incorporate standardized diagnostic instruments alongside individualized psychotherapy, a structured clinical process that may coordinate with motor-development rehabilitation at Sports Performance Physical Therapy - Chula Vista when physical symptoms co-present. The practice serves clients across developmental and adult populations, applying evidence-based interventions for behavioral, emotional, and relational concerns. Integrated care pathways can include acupuncture-based nervous-system regulation through Urban Sage Acupuncture + Wellness when somatic stress indicators warrant complementary intervention. Evaluation protocols utilize the DSM-5-TR diagnostic framework combined with functional behavioral assessment tools to quantify baseline severity and track session-over-session symptom reduction.
