Dr. Louis is a fellowship-trained neurosurgeon and Program Director of
the Skull Base and Pituitary Tumor Program at Hoag Neurosciences Institute.
Dr. Louis has particular expertise in endoscopic and minimally invasive
treatment of benign and malignant brain tumors, sellar and parasellar
tumors and skull base tumors. Through the use of cutting-edge neuroimaging
and neuro-navigational equipment, he utilizes the concept of keyhole neurosurgery,
minimizing the damage to surrounding brain, vascular and soft tissue structures.
Dr. Louis believes that most brain and skull base tumors can be resected
through small openings or by utilizing naturally occurring orifices. This
approach has been demonstrated to decrease post-operative pain, minimize
neurologic complications and shorten length of hospitalization, resulting
in better outcomes for his patients.
His clinical interests include minimally invasive brain tumor surgery,
skull base and pituitary surgery, neuroendoscopy, microneurosurgery, complex
spinal surgery and peripheral nerve surgery. In his practice, Dr. Louis
employs a thoughtfully conservative approach, dedicated to delivering
outstanding neurosurgical care with an individual, patient-centered focus.
Dr. Louis was raised in a suburb of Boston and completed his undergraduate
education at Boston University. After completing medical school, Dr. Louis
was accepted into residency in neurological surgery at the University
of Virginia, under the direction and mentorship of Dr. John Jane. During
his six years at UVA, he completed more than 1200 cases, spanning the
breadth of cranial and spinal neurosurgery. Specifically, Dr. Louis focused
his training on complex brain tumor, skull base and pituitary surgery
and had the honor of training extensively under Dr. Edward Oldfield, widely
considered the foremost pituitary surgeon in the world. After completing
his Chief Residency in neurosurgery, Dr. Louis went on to more advanced
subspecialty training, completing a fellowship in Minimally Invasive Neurosurgery
under the mentorship of Dr. Daniel Kelly at the John Wayne Cancer Institute.
Dr. Louis is one of only a handful of fellowship-trained minimally invasive
neurosurgeons in the nation and the only one in Orange County with this
Beyond his specialty training in the neurosurgical treatment of brain and
pituitary tumors, Dr. Louis has a particular interest in microsurgical
neuroanatomy. Specifically, his focus is on advanced understanding of
neuroanatomy and the development of new neurosurgical procedures. He has
authored over 60 peer-reviewed scientific publications and numerous book
chapters. From 2011-2013, he served as an instructor of Neuroscience and
Anatomy in the Brain, Mind and Behavior Course at the University of Virginia.
In 2012, Dr. Louis was appointed Director of the Skull Base Anatomical
Dissection Laboratory at the University of Virginia. His love of teaching
has won him numerous awards for excellence in both teaching and research.
He is a member of the American Association of Neurological Surgeons (AANS),
Congress of Neurological Surgeons (CNS), North American Skull Base Society
(NASBS), Foundation for International Education in Neurosurgery (FIENS)
and the American Association of Clinical Anatomists (AACA).
Internationally, his passion for teaching and philanthropy has led him
to pursue neurosurgical humanitarian efforts in East Africa. As part of
Madaktari and the Foundation for International Education in Neurosurgery,
Dr. Louis leads multidisciplinary neurosurgical teams on relief efforts
to Tanzania. In recognition of his efforts, in 2011, Dr. Louis was awarded
the prestigious American Association of Neurological Surgeons YNC Public
Service Citation for outstanding humanitarian relief efforts in Africa.
