NEST was co-founded by Dr. Allyson Hentel-Koplin and Dr. Annette Zygmunt

We met while enrolled in the School Neuropsychology  Post-Graduate Certification Program (SNP) of the American Board of School Neuropsychology. After completing training, we founded NEST with the goal of providing comprehensive neuropsychological assessments  that are knowledgeable, relevant and strength-based. Our core ideology is that assessment recommendations should be specific to a child's learning needs while also building on his or her strengths. We also strongly believe that results should be communicated in a clear and concise manner and that interventions should be practical and make sense in a child's life.  Our professional experience in schools and hospital clinics, as well as our specialty training at SNP, set NEST apart.
