Dr. Frederick H. Fung might've saved Lois Brown's life. "I'd seen another internist who ignored my symptoms of chest tightness and discomfort," Brown says. "I went to Dr. Fung with these concerns, and he had tests done immediately. Within a few days, he had a stint put in my coronary artery! He has an incredible knowledge of disorders, diseases, medications and treatments. I feel completely comfortable in his competent care."
