About Us

Fellowship trained in the treatment of movement disorders, the GNC team offers extensive experience in state-of-the-art patient care. As experts in Deep Brain Stimulation (DBS) and other neuromodulation therapies, GNC focuses on maintaining and restoring function while providing lasting relief from patient-specific disease symptoms through the use of surgical and non-surgical treatments.

We offer specialized consultation for the treatment of:

  • Parkinson’s disease
  • Essential tremor
  • Dystonia
  • Tourette syndrome
  • Huntington’s disease

GNC offers services to patients, family members, and caregivers. GNC’s face-to-face physician consultation time, individualized treatment plans and customized education materials help patients take an active role in directing their care and achieving personalized quality-of-life goals.

Not only do we assist the patient, but we offer training and ongoing support for the local physician that carries out principle, day-to-day care. GNC has served as a resource for physicians and healthcare providers worldwide. Referring physicians receive consultation and training with ongoing patient-specific communication regarding advances in treatment options including, but not limited to, DBS. Together we work to ensure newly diagnosed patients get off to the right start and that all patients receive optimal care.




Erwin B. Montgomery Jr. MD

Inspired by his patients and passionate about his craft, Dr. Montgomery has treated over 10,000 Parkinson’s patients, performed hundreds of DBS surgeries, trained fellows in intraoperative neurophysiological monitoring and invented various hardware and software for neurophysiological monitoring and analysis.

A leading authority on movement disorders and DBS programming, he enjoys 40 years of research experience in electroneurophysiology (extracellular neuronal action potential recordings in particular) and 15 years of experience in human pre-, intra- and postoperative DBS.

Dr. Montgomery’s research has focused on understanding how the brain controls movement and how that control goes awry when a person develops Parkinson’s disease or another movement disorder. Dr. Montgomery studies how DBS works with the intention of improving this treatment for an expanding array of neurological and psychiatric disorders.

He has written a number of industry texts, including Deep Brain Stimulation Programming: Principles and Practice; Deep Brain Stimulation Intraoperative Neurophysiological Monitoring: Principles, Practice and Cases; and Twenty Things to Know About Deep Brain Stimulation.

Meet our current partners:

Thiel College

Located in Greenville, Pennsylvania and known for its commitment to student success and growth, Thiel boasts dedicated faculty, numerous leadership opportunities and a wide variety of student activities and organizations.

In 2005, we joined Thiel in developing the Thiel College Neuroscience Program, an interdisciplinary endeavor that both exploits and improves the interface between biology and psychology. The program emphasizes experiential learning by requiring students to gain laboratory experience, take field trips, and complete internships and senior research projects. In doing so it prepares students for graduate programs in neuroscience, biology and psychology, and professional programs in various areas of allied health. It also readies them for such entry-level positions as technologist and sales representative.

In addition to working with Thiel College’s Neuroscience Program, GNC has developed innovative, auxiliary partnerships with medical device manufacturers and other biotechnology leaders. These partnerships will benefit GNC patients, Thiel students and medical communities worldwide.

Greenville Area Economic Development Corporation (GAEDC)

A private, nonprofit, local corporation established to promote the economic well-being of the Greenville Area and its citizens, GAEDC aids new businesses and helps to retain established ones for the purpose of creating jobs in the region.
