Behavioral Health of North Florida is a Jacksonville psychology practice with an integrative approach that combines neuropsychological expertise with attention to how early relationships shape thinking, emotion, and connection over time. The practice centers on Jonathan Gross, a neuropsychologist whose work explores links between brain function, mental health, and enduring relational patterns, with particular emphasis on Attachment Theory and narrative coherence. Its care is designed to help patients understand longstanding interpersonal and emotional patterns while addressing mental and cognitive well-being. The team also includes Lauren Miller, whose background in psychology and prior experience in the fitness industry adds broader real-world perspective to the practice.
