Welcome to my Web page. Practicing gastroenterology at Kaiser Permanente has been the most rewarding part of my career. At Kaiser Permanente I have the freedom to practice medicine in an environment that allows me to give the best possible care to my patients. As a gastroenterologist in private practice for four years prior to coming here, I am especially thankful that my current environment allows me to make the decisions regarding what I believe is best for my patients. Kaiser Permanente respects my level of expertise as your specialist and has always supported my clinical decisions. This was rare for me prior to becoming a Kaiser Permanente physician. Biography I decided to leave Philadelphia (where I was born) after graduating from medical school in 1990. I must admit that one of the major factors in my decision to move to Southern California was the weather! I have a lovely wife, who is also an internal medicine physician at Kaiser Permanente in Bellflower. I have two young boys. I spend a great deal of time attending swim meets, baseball games, soccer games, and basketball games. I help coach Pony League baseball. I help both of my children learn piano (which I also play). Besides my complete devotion to my family and my practice, I am an avid reader. I enjoy science fiction, history (especially military history), and the great novels of our time. Ask me anytime what I have been reading! About my practice I believe that one of the major purposes in my life is to seek the well-being of my patients. I will always try to go that extra mile to provide excellent-quality care and be as responsive to their needs as possible. I believe that prevention is the best way to stay healthy. I am actively working to make colorectal cancer screening at Kaiser Permanente the best in this country. My greatest enjoyment in clinical practice is performing biliary endoscopy. I also enjoy caring for patients with chronic liver disease and inflammatory bowel disease (Crohn's disease and ulcerative colitis). How I thrive I enjoy snow skiing (and planning ski trips as well as dreaming of skiing), weight lifting, and cardiovascular training (on elliptical machines and treadmills). I believe that having a healthy body leads to having a healthy mind and life. I also spend some time enjoying deep water fishing in Cabo. I once caught a 510-pound black marlin on a 50-pound test line!
