Karla Aguilu, PsyD

Licensed Psychologist

Pronouns: She/Her

Dr. Aguilu is a compassionate and dedicated psychologist who believes that a strong therapeutic relationship is at the heart of meaningful treatment. She approaches each patient with warmth, empathy, and genuine respect, taking the time to understand not only the challenges they are experiencing, but also the person behind those challenges. Her goal is to create a safe, supportive environment where patients feel heard, understood, and accepted while working collaboratively toward meaningful change.

With over 18 years of experience providing psychological services across the lifespan, Dr. Aguilu works with children, adolescents, and adults experiencing a wide range of emotional and life challenges. She has particular experience working with anxiety, depression, grief, end-of-life concerns, blended and complex family situations, major life transitions, and immigration-related psychological evaluations.

Dr. Aguilu takes an individualized approach to treatment, recognizing that there is no single approach that works for everyone. She draws from evidence-based approaches including Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and Trauma-Focused Cognitive Behavioral Therapy (TF-CBT), while adapting interventions to each patient's unique needs, background, strengths, and goals. She believes that effective treatment is not simply about applying a technique, but about building a trusting relationship in which patients feel supported as they work through difficult experiences.

Dr. Aguilu completed her graduate work at Nova Southeastern University and her graduate-level clinical training at the Children's Institute in Los Angeles, California. As a native Spanish speaker, she is also committed to providing culturally responsive and accessible psychological services to Spanish-speaking individuals and families.
