Dr. Danaë Rollet - Founder
Danaë Rollet, Psy.D., HSP is a Licensed Clinical Psychologist (TN #4113) and the founder of Summit Neuropsychology. She specializes in comprehensive neuropsychological, developmental, and psychoeducational evaluations for children, adolescents, and young adults. Dr. Rollet’s passion for the assessment process is rooted in witnessing how a thoughtful, well-conducted evaluation can reshape the way families, educators, and providers understand and support an individual’s unique needs. She approaches each evaluation as an opportunity to bring clarity to complexity, translating nuanced findings into thoughtful, practical recommendations that make a tangible difference at home, in the classroom, and beyond.
Dr. Rollet received postdoctoral training in pediatric neuropsychology and maintains ongoing consultation and supervision with Haley Sims, Psy.D., a pediatric neuropsychologist based in Chicago, IL. Dr. Rollet’s perspective reflects a global upbringing: as a French citizen raised across five countries, and now based in the United States for over a decade, she brings a refined, cross-cultural lens to her work. Outside the office, she enjoys reading, exploring Nashville's food scene, and spending time outdoors with her family.
