Greetings! I am a board certified general surgeon with over two decades of clinical practice since completing my doctorate and surgical residency at Loma Linda University School of Medicine. I treat the full spectrum of general surgical problems including hernias, gallbladder disease, breast cancer and benign conditions, with special interest in melanoma and trauma. I grew up in this area, and spent my youth in extensive manual labor which has contributed to both my dexterity and efficiency of movement.
I decided to become a physician during high school because I wanted to use my talents to help people. What I like most is being able to treat the whole person, resolving their health problems, and saving lives. I chose Surgery because it best fit my aptitudes, trained me to handle emergencies, and was adaptable for mission service. I’ve enjoyed volunteering during my teens at Inland Valley Medical Center, rotating in Kenya during medical school, and service trips to Peru, to China teaching Advanced Trauma Life Support (ATLS), and to India to teach Laparoscopic Surgery. I enjoy people and helping them survive and thrive, through operations or non-operative management.
I serve my community on our hospital's Ethics Committee, as the trauma director of our regional trauma center, and lead our Surgery Residency trainging the next generation of well qualified surgeons.
I enjoy outings with my family, horticulture, learning every day, exercising/hiking/camping/surfing, and playing the bagpipes.
