Dr. Shokei Yamada, MD, PhD, FACS, Professor Emeritus
Shokei Yamada, a native of Shimizu, Japan, followed the tradition of six generations of his family in becoming a physician, the earlier generations serving as consultants to the Shogun families. He received his B.S., M.D., and Ph.D from Jikei University at the School of Medicine, in Tokyo. After completing a general surgery residency, he had neurosurgery training at the University of Toronto under Professor E. Harry Botterell, at the University of Chicago under Professors Joseph P. Evans and Sean E Mullan, and at the Oregon Health Science University under Professor George M. Austin. After serving as an instructor in neurosurgery at Jikei for one year, he returned to Oregon as a Research Associate.
In 1964, he was appointed as attending staff to Professor Julian R. Youmans at the Medical University of South Carolina in Charleston, SC. Later, he served as Associate to Professor Phanor Perot and as Chief of Neurosurgery at the Veterans Administration Hospital, participating in the residency training as a co-director. In 1973, he joined Professor George Austin at Loma Linda University School of Medicine as Assistant Professor and was subsequently promoted to Associate Professor and then to Professor, Division of Neurosurgery. He served as Chairman of Neurosurgery at Loma Linda from 1989 to 1995. In 1989 he was elected to AOA for his contribution to medical science.
He has consistently been involved in research: in Neurophysiology in Toronto and Oregon, and in Neuropathology at the University of Chicago. In South Carolina, he began the use of longitudinal myelotomy for control of mass spasms, and received the Distinguished Award for his presentation of this procedure at the Congress of Neurological Surgeons. He was the first to conduct animal and then human research for changes in intracranial pressure, intrasagittal pressure, as well as changing in ventriculo-atrial and peritoneal shunting rate during positional changes from recumbent to upright position. At Loma Linda, he developed an experimental model of tethered spinal cord and was the first to apply reflectance spectrophotometry to the animal model as well as to the human spinal cord. His results clarified the impairment of oxidative metabolism as the underlying mechanisms of this syndrome. His innovative technique for resection of AVMs in the functional areas of the brain was derived from extensive studies of hemodynamic anatomy of arteriovenous malformations. Recently, he developed the concept of AVM compartments that facilitated surgical management of large AVMs. The bypass coaptation procedure, a new technique he designed, has allowed the restoration of groups of muscles distributed by avulsed cervical nerves. His publications of 120 articles and chapters were the product of his originality. The book “Tethered Cord Syndrome,” which he edited for AANS Publications in 1996, will be renewed as the 2nd edition by Thieme Publisher in 2005. He is also the editor of “AVMs in Functional Areas” published from Futura Publications with the support of AANS in 1999. He serves on the Editorial Board of Neurological Research. After retirement from Loma Linda University Medical Center in 1999, he participates in teaching and research at the Medical Center, and also in training residents as a consultant at Arrowhead Regional Medical Center and Kaiser Permanente Medical Center, Fontana, CA.
He is married to Rachel Thomasson of York, SC. They have two daughters, Vivian, Assistant Professor of Clinical Psychology at the University of Central Florida, and Cheryl, a communication specialist. His son, Brian, urologist, and daughter-in-law, Jennifer, anesthesiologist, both graduates of Wake Forest University School of Medicine, participate in teaching at Medical College of Albany, Albany, New York.

Todd Goldenberg, MD
I attended USC School of Medicine and did my Neurosurgery residency at UC Irvine. During residency training I spent a year doing epilepsy research, and at that time, my wife-to-be was an undergraduate student working in the same lab. We fell in love studying rat brains and have been inseparable ever since.
My wife is an attorney, but she put her career on hold to be a full-time mom. We have a son, Max, and a daughter, Talia -- they keep us busy and thoroughly entertained. Photography has become a major hobby for me and my kids are my favorite subjects. Mountain biking is another hobby and my favorite form of exercise. I look forward to riding with my kids when they get older.
I feel very fortunate to be part of the Kaiser Permanente team. In our Neurosurgery Department, I have colleagues who I truly respect and admire, and we work well together to provide outstanding service to our patients. Neurosurgery is a "team sport" and the Neurosurgery Residents are a very important part of our team. We have a busy service with over 600 operative cases per year. The residents are exposed to a variety of neurosurgical disorders and they play an active role in patient management with gradually increasing responsibility as they progress in their training.

Daniel J. Won, MD
My special interest is in pediatric neurosurgery. I had the privilege of training under the late Dr. Fred Epstein at Beth Israel Medical Center-North Division in New York City. As my mentors have always taught me, I strive for perfection and the best possible outcome. Trust in God has shaped my life and career and I consider human life a gift from God to all humanity. I am involved with quality improvement in our neurosurgery department, and work to help reduce and eliminate complications in neurosurgery.
I am married to a pediatrician and have two boys. I enjoy living in Southern California because of the diverse culture and pleasant weather. My family enjoys dining out on weekends in various ethnic restaurants. I enjoy working at Fontana Medical Center because I am able to balance work and family life. My spare time is spent with woodworking and working on various small projects. Keeping the Sabbath and participating in church activities on weekends help my family spend quality time together.
