If your child or teen is struggling with anxiety, attention difficulties, or big emotions — you have come to the right place. I am a clinical psychologist with over a decade of experience in the United States and Singapore, specializing in children, adolescents, and families. I work with anxiety, mood disorders, ADHD, and behavioral challenges using evidence-based approaches tailored to each individual. I also see adults navigating stress, life transitions, and chronic illness. Every person I work with deserves warmth, clinical rigor, and a clear path forward. I offer a free 15-minute consultation — because the right fit matters.
My expertise includes ADHD and psychological assessments across the lifespan, plus therapy for anxiety, depression, behavioral difficulties, and adjustment to chronic illness. I use CBT, ACT, and behavioral interventions — always tailored to the person in front of me. Book a free 15-minute consultation to see if we are a good fit.
Reaching out takes courage, and I respect that. Whether you are a parent seeking answers for your child, a young person navigating a difficult chapter, or an adult ready for change — I am here. At Lightfull Psychology, progress happens when you feel truly understood. Your free 15-minute consultation is just a call away.
