Multilingual psychologist Pei-Chen Emily Wu, PsyD, in Encinitas earned her doctorate from Alliant International University and has practiced clinical psychology since 2008 at the LifeStance Health office on Santa Fe Drive near Encinitas Community Park.

LifeStance Health operates as a national behavioral health network providing psychiatry, psychology, and therapy through licensed clinicians across multiple California offices. Wu delivers therapy in English, Mandarin, and Taiwanese using CBT, Acceptance and Commitment Therapy, Motivational Interviewing, and Solution-Focused Therapy, coordinating with primary care providers including Dr. Bruce J.

Advanced cases involve CBT-I (Cognitive Behavioral Therapy for Insomnia) protocols targeting sleep-architecture disruption in older adults with comorbid depression and somatoform symptom presentations.
