Where I practice
Thanks for visiting this page to learn more about me. I am an orthopedic surgeon with subspecialty training in hand and upper extremity surgery. My philosophy is that you and I can work together to determine the best remedy for whatever it is that ails you and your hands and arms.
I grew up in Palm Desert, CA, and spent most of the time in the pool trying to stay cool. I moved on to Stanford (Go Cardinal!) for my undergraduate degree in human biology, followed by medical school in Philadelphia. I went through medical school on a scholarship from the United States Navy, and after graduation, I completed a surgical internship at Naval Medical Center San Diego. I spent two years with the 1st Marine Division, including a deployment with the 2nd Battalion, 5th Marines as their Battalion Surgeon during the invasion of Iraq. I then went through orthopedic surgery residency back at Naval Medical Center San Diego, followed by a fellowship in hand & microvascular surgery at the Philadelphia Hand Center. I returned to Naval Medical Center San Diego as staff, and deployed for seven months to Afghanistan in 2012, where I had the honor of caring for our sailors, soldiers, and Marines. I joined Kaiser Permanente when I completed my service in 2014.
About my practice
My practice primarily involves surgery of the hands, wrists, forearms and elbows. I love the intricacy of hand surgery in everything from the fairly common conditions such as carpal tunnel and trigger finger, to the latest advances in peripheral nerve surgery, arthroscopic surgery, and reconstructive surgery. By being active in several national and international medical organizations, I feel I can always provide high-quality evidence-based care to you, my patients. My clinic staff and our team of therapists are an integral part of the care team. Together we will all work with you to get you back to functioning at your best.
How I thrive
I thrive with the personal interactions I have with my family, colleagues, and patients each day. I love the water, and enjoy an early morning surf or an evening swim with my local masters program. I find mind and body relaxation from building and shaping hollow wooden surfboards. In the fall, you can find me glued to Stanford football games. My best time, though, is the time I spend with my wife and two children learning new things, experiencing new activities, and just hanging around together.
