Practicing from the Psychiatric Centers at San Diego suite in Chula Vista's Rancho Del Rey neighborhood, Dr. Leticia Hennessey is a clinical psychologist who holds a Doctor of Psychology degree and has provided testing and psychotherapy services from Tierra Del Rey since 2007. Her psychotherapy and behavioral-analysis practice treats a broad range of emotional and psychological conditions, drawing referrals from the South Bay primary-care network including San Ysidro Health Chula Vista for patients transitioning from medical intake to behavioral-health evaluation. Affiliated with Sharp Mesa Vista Hospital and enrolled in the PECOS Medicare system, she provides psychological testing that evaluates cognitive functioning, personality profiles, and aptitude measures for diagnostic and treatment-planning purposes. Assessment protocols cover ADHD screening, mood-disorder differentiation, learning-disability evaluation, and personality profiling using standardized psychometric instruments, serving patients referred from schools, courts, and medical providers across the 91910 ZIP and surrounding western Chula Vista communities. Neuropsychological and forensic-evaluation protocols sometimes require corroborative biological data such as substance screens, metabolic panels, or thyroid-function tests, facilitated through Fastest Labs of Chula Vista to rule out organic causes of mood and cognitive symptoms. Full psychoeducational batteries combine the Woodcock-Johnson IV Tests of Achievement with projective instruments such as the Rorschach Inkblot Method and Thematic Apperception Test to generate integrated reports that differentiate emotional disorders from learning disabilities.
