Licensed Clinical Psychologist


Hello! My name is Hannah Lee, and I am a licensed clinical psychologist (PSY26419). Understanding the issue you are struggling with is one of the first steps in finding the right help. Having an incorrect diagnosis or an incomplete picture of your struggles can prevent you from finding the right kind of treatment for you. My goal is to use psychological testing and assessment to clarify what is underlying your struggles and to provide you practical resources so you can get started on your road to healing and growth. When I meet with you for testing and assessment, I will work to get to know you as a whole person rather than reduce you to a bunch of numbers and test scores. 


I offer psychodiagnostic, psychoeducational, and neuropsychological testing for clients across the age span, from age 3 and up. I am also bilingual in English and Korean, and I am a certified Prepare/Enrich counselor who can help engaged couples prepare for marriage. 


Thank you for taking the time to get to know me. I look forward to getting to know you!
