As a clinical psychologist with over a decade of experience, I’m passionate about helping people understand themselves more deeply and move toward meaningful change. I bring empathy and curiosity to each session, whether we're identifying patterns, clarifying goals, or exploring what matters most to you. Therapy and psychological assessment can deepen self-knowledge and support lasting shifts in how you relate to yourself and others—in work, school, relationships, and daily life. I specialize in comprehensive evaluations (including autism, ADHD, and cognitive testing) to support clarity, insight, and next steps in care.
I offer assessments for all ages and therapy for adolescents and adults. I integrate diverse approaches such as ACT, DBT, psychodynamic, neuroaffirming, and strengths-based. I take a holistic view of health and consider the connections between mind, body, relationships, and values. I also provide supervision and consultation for mental health professionals.
Choosing to begin therapy, pursue an assessment, or seek consultation is a meaningful step toward clarity, growth, positive change, and a sign of strength. I provide collaborative and actionable support to help you better understand yourself and move toward your goals.
