About me

I hate to confess that I am a California transplant. I was born and raised in the Mother Lode of the Sierra Nevada foothills of California, in a small gold mining and logging town called Grass Valley. Good fortune and hard work led me to the anesthesia department at Stanford University, where I trained with pioneers in the field of anesthesia. I went on to earn a Master of Business Administration, but I must give my wife credit. She worked double duty to support the family and help cover my clinical anesthesia responsibilities. I have now had multiple department chairman positions where I have called on her to continue this support. Probably my greatest achievement and most challenging work has been to help raise eight children. It may be many years before any of them understand my frequent statement: "You will always be treated fairly but not necessarily equally."

About my practice

After many years in private practice, including 10 years of cardiac anesthesia, I was lured to Kaiser Permanente, which I believe is the model for future medicine in this country. Quality is the keystone of this health system and my passion. There is an unsurpassed commitment to patient safety and emphasis on preventive care. Coordinated integrative medicine provides the best care. Successful anesthesia involves coordination and communication with many subspecialties. I consider it a privilege to be in this medical subspecialty where I can minimize the pain, anxiety, and stress of surgery. My goal is to provide utmost quality, utilizing evidence-based medicine, while treating patients as if family. My skill is providing anesthesia for the complex case and applying goal-directed therapy. I am the current Northwest regional anesthesia chief. I relish the opportunity to oversee and improve the quality of anesthesia for Kaiser Permanente members. My department is involved in multiple quality initiatives: reduction of surgical site infection, surgical and post-op care of patients with obstructive sleep apnea, development of a regionalized pediatric anesthesia care system, improvement of patient safety in the surgical suite, development of standardized orthopedic care for total joints, development of an acute pain service, and outpatient pain catheter service.

How I thrive

Over the past five years, Kaiser Permanente has changed my life. I have adopted the Kaiser Permanente motto of Thrive. I have been a vegan for two years now with the support of our cafeteria at Sunnyside Medical Center. I have lost 30 pounds while becoming increasingly active in sports, specifically swimming, running, and biking. Now I am training for triathlons. My hope is to eventually run with my two 3-year-old goldendoodles, who have not been separated since birth. The problem is they tangle themselves in their leashes with me included. I probably know every Meals on Wheels route in Portland, Oregon, and can honestly say I feel a loss when one "regular" gets taken off the roster. We've been actively involved in delivering food for 15 years. My wife and I have raised all our children to value and participate regularly in community service. We have eight children and are actively involved in their lives. I am a sports buff and must confess I enjoy lazing on the couch and watching football games on the weekends. My other "couch" passion is reading modern history.
