Jon-Paul Pepper, MD
Dr. Pepper is a double-board certified surgeon who specializes in aesthetic and reconstructive surgery of the face, in particular surgery for the treatment of facial paralysis. He is the Director of the Stanford Facial Nerve Center. His areas of expertise include facial reanimation surgery, facelift surgery, rhinoplasty, and the reconstruction of the face after skin cancer resection. Dr. Pepper performed his undergraduate studies at Brown University, majoring in Neuroscience. He completed a one-year research fellowship at the National Institutes of Health in preparation for a career in academic medicine. He was awarded his M.D. at the University of California, Irvine, graduating with highest honors and Alpha Omega Alpha designation in 2007. He went to the University of Michigan for residency training in Otolaryngology – Head & Neck Surgery in 2012. He then completed fellowship training in Facial Plastic & Reconstructive Surgery in 2013, also at the University of Michigan.
Dr. Pepper and was honored to receive the highest board score in the nation on the American Board of Facial Plastic & Reconstructive Surgery examination in 2013. For this accomplishment, he was given the Jack R. Anderson Award for Scholastic Achievement.
While on faculty at the University of Southern California from 2013-2017, Dr. Pepper established the USC Facial Nerve Center, and also established a basic science lab that explored new treatments for facial paralysis. His research was recognized by the American Academy of Facial Plastic & Reconstructive Surgery, for which he was given the Research Scholar Award in 2014. This award, with other grant support, has permitted the growth of a basic science research program under his direction which is dedicated to facial nerve regeneration.
In 2017, he joined the faculty at Stanford School of Medicine, and was specifically recruited to launch the Stanford Facial Nerve Center.

Jaime López, MD
Director, Intraoperative Neurophysiologic Monitoring Program
Associate Professor of Neurology and Neurological Sciences, and Neurosurgery
Dr. López completed his residency in Neurology and Fellowship in Clinical Neurophysiology and Neuromuscular Diseases with special emphasis in electromyography at Stanford University Medical Center. In 1994, Dr. López established the Intraoperative Neurophysiologic Monitoring (IONM) Program at Stanford. The program specializes in assessing intraoperative nervous system function, including facial and all the motor cranial nerves, to assist surgeons in preserving nerve function, prevent intraoperative nerve injury, and improve patient safety and postoperative outcome. In addition, Dr. López has extensive experience in the pre- and postoperative evaluation and assessment of facial and other cranial nerve disorders using nerve conduction studies (NCS), electromyography (EMG), blink reflex electrophysiologic studies, and electroneuronography (ENoG) which is a specific electrical stimulation study of the facial nerve. Dr. López also has vast experience in the medical and botulinum toxin treatment of facial and oromandibular disorders. Dr. López continues to research the use of innovative techniques for intraoperative monitoring of different regions of the nervous system as well as their use in the pre- and postoperative care of patients.
