Licensed Psychologist 



I am a clinical psychologist (PSY30432) who specializes in pediatric neuropsychology. I have extensive experience conducting neuropsychological and psychological evaluations with children, adolescents, and young adults in a variety of settings ranging from outpatient clinics and schools, juvenile justice programs, and inpatient psychiatric hospitals. I also have worked with many individuals experiencing a variety of neurodevelopmental, medical, and psychiatric struggles.  


I believe a comprehensive evaluation is vital to understanding an individual’s unique set of cognitive strengths and weaknesses, particularly as they relate to learning and academic success, as well as behavioral development and independent functioning. A thorough assessment is so important when considering effective treatments and interventions. I look forward to meeting you and answering any questions you may have about the evaluation process.
