Do you or your child often feel misunderstood, or wonder what is at the root of challenging behaviors, emotions, or learning struggles? Do you feel overwhelmed by questions about diagnosis, types of therapy, or support options, and wish you had a clear roadmap forward? Whether you are a parent seeking insight into your child’s development, or an adult hoping to better understand yourself, I’m here to help you find clarity in the path ahead.
I offer comprehensive diagnostic evaluations across the lifespan—from toddlers (18 months+) through adulthood—with a particular focus on neurodiversity including Autism and ADHD. I also assess for mood disorders and learning disorders. My approach goes beyond a simple “yes” or “no” diagnosis; I strive to provide insight into your unique concerns and needs.
Using evidence-based assessment tools, I take time to explore your or your child's unique strengths and needs. My collaborative, supportive approach ensures you feel truly heard, respected, and empowered. By the end of our evaluation, you’ll have a custom report that’s easy to understand and includes actionable recommendations tailored to you.
