Our Story

Neurology, Psychiatry, and Balance Therapy Center was founded in 2012 by triple board-certified neurologist and psychiatrist Dr. Sonya Knight. The practice was built with a single purpose: to treat the whole person, not just the diagnosis.

Located in Blue Bell, Pennsylvania, NPBTC offers an integrated model of care that brings together neurology, psychiatry, and physical therapy under one roof. By combining brain-based medicine with personalized physical rehabilitation and mental health support, we’re able to deliver more complete, compassionate care for complex conditions.

We are proud to be one of the few practices in the region with this level of collaboration, and even prouder of the thousands of patients we’ve helped over the past decade.

A Practice Built on Collaboration

Whether you’re here for depression, epilepsy, migraines, OCD, dizziness, or functional neurological symptoms, we bring together a team that looks at your full picture.

Our approach isn’t “pass-the-patient”—it’s coordinated, integrated, and deeply personal.

We believe healing happens when providers work together. That’s why your care team may include:

Neurology

Psychiatry

Physical Therapy

Clinical support staff trained to guide you through every step

You’ll never feel like just a chart number here.
