I believe in the special and sacred relationship between doctor and patient. I apply the latest standards of care in treating my patients, and I add my personal touch to it. This include listening to my patients, sharing their feelings and emotions, and talking sincerely to their hearts and minds to help them pass through the journey of their disease. I have special interests in Gastrointestinal cancer, Urologic cancers, Lymphoma, Leukemia, and lung cancer. I may not see the cure of all cancers in my life time, but I want to do my best to get closer to that goal.
