"Healthcare should always be a personal matter. I make an honest effort to get to know my patients and become an ongoing part of their lives.  My patients are more than just a name and medical file on a computer screen.  One of my favorite quotes is by Sir William Osler: 'The good physician treats the disease; the great physician treats the patient who has the disease'.  I also believe that if we make it pleasant and convenient for patients to come in, they're going to take better care of themselves. I don't mind working in the evening or a weekend because I know patients appreciate it."


Dr. Gebhard is a California native, having grown up in the south bay area of Los Angeles.  He attended Loma Linda University for his undergraduate, graduate and medical school education.  He completed his residency in Family Medicine at the University of California, Irvine.  Dr. Gebhard is Board Certified in Family Medicine and has a Master of Science in Nutrition.  He spends his free time road biking, restoring classic automobiles, sailing, and working towards his private pilot license.
