Jessica Gaines, Psy.D. in Encinitas holds California psychology license PSY28223 and practices at The Halliday Center for Psychotherapy & Wellness on Santa Fe Drive, with doctoral training from Alliant International University-Los Angeles. The clinical specialization in developmental psychodiagnostic assessment includes administration of the Achenbach Child Behavior Checklist, Bayley Scales of Infant Development, and Ages and Stages Questionnaire, a pediatric evaluation scope that interfaces with the developmental pediatric work at Dr. Anna Mendenhall in Encinitas. Play therapy and dyad therapy interventions for preschool through adolescent populations address behavioral disruption, family conflict, and socialization challenges. The Halliday Center's multi-clinician model provides coordinated care across individual child therapy, family therapy, and parent education, positioned within Encinitas's integrative health landscape that includes ActiveMed Integrative Health Center. Classroom behavioral observation and parent-teacher consultation round out the practice's school-based support services. Highest-complexity engagements involve comprehensive developmental psychodiagnostic batteries combining the DIAL-3, Roberts-2, and Functional Emotional Assessment Scale across multi-domain evaluation of preschool and early-childhood neurodevelopmental presentations.
