  • Biography



    I enjoy partnering with my patients to maximize their health by combining the most up-to-date medical knowledge with a compassionate and caring manner.

    I have been enriched over the past ten years by my relationships with my patients. I continue to keep in touch with many of my patients in Michigan. I look forward to establishing the same kind of relationships in my practice here in Orange County.

    I love the complexity and variety that Internal Medicine offers. As a faculty member at the University of Michigan, I enjoyed teaching Internal Medicine residents and medical students the complexities of clinical medicine. I consider life-long learning to be fundamental to the practice of medicine.

    I am having fun exploring the beauty of California with my family. I also enjoy biking, skiing, tennis and cooking.
