The Evolution of the Practice: From Philadelphia to the Shore

Established in 2016 in Wayne, Pennsylvania, NeuroAnalytics, LLC, Dr. Perrin’s original private practice, served as a primary referral source for major academic institutions and healthcare providers in the Mainline area of Philadelphia.

Like many people, the pandemic inspired a new appreciation for a healthier work-life balance and in 2023, Dr. Perrin and her family relocated to the New Jersey Shore. Through talking to local school staff, healthcare providers, friends and neighbors, Dr. Perrin began to appreciate the need for additional mental health resources and was motivated to open a local practice. In 2025, Dr. Perrin established BrainWaves, Comprehensive Neuropsychology, located in Bay Head, New Jersey.
