Our Staff

Texas Neurosurgery is committed to providing the highest quality of healthcare.  Our practice is centered on each patient who walks into our office. In order to assist you with your healthcare needs, our practice has dedicated physician assistants who work closely with the physicians so you can receive the best possible healthcare in an efficient and timely manner. The physicians and their physician assistants are here to provide you with a complete understanding of your condition and to offer you the best personalized care possible.

Physician Assistants are healthcare professionals licensed by the state board to practice medicine with supervision by a licensed physician. Under the supervision of a physician, a physician assistant can diagnose, treat and monitor common acute and chronic diseases, as well as, provide healthcare maintenance care. "Supervision" does not require the constant physical presence of a supervising physician, rather oversight and responsibility for the medical services provided.

Services provided by our physician assistant may include:

  • Obtaining histories and performing physical exams
  • Ordering and/or performing diagnostic and therapeutic procedures
  • Formulation of a working diagnosis
  • Developing and implementing a treatment plan
  • Monitoring the effectiveness of therapeutic interventions
  • Assisting in surgery
  • Counseling and education
  • Writing prescriptions (where allowed by law)
  • Making appropriate referrals
