Katrina Zeljak LMFT in Carlsbad's La Costa corridor holds dual designations as a Registered Play Therapist-Supervisor and EMDR-certified clinician specializing in child and family therapy on El Camino Real. Her play-based clinical model uses structured interventions to rewire dysregulated nervous systems in children, a sensory-integration approach shared by occupational therapy practices including Eat. Play. Love. Occupational Therapy along the same corridor. Zeljak also carries a Registered Sandplay Practitioner credential and serves as a trainer for the City of Carlsbad GUIDE Program, coaching counseling associates in school-based play techniques. Treatment protocols span anxiety, PTSD, behavioral issues, and separation anxiety, drawing from Attachment-Based and Child-Parent Psychotherapy frameworks within the La Costa behavioral-health cluster that includes The Child Psychology Center. Clinical sessions integrate EMDR bilateral stimulation, Jungian sandtray symbolism, and directive play interventions calibrated to each child's developmental stage and presenting trauma profile.
