My son suffered from his skin problem for over three years. We visited local doctors repeatedly to seek medical treatment; but unfortunately, my son's condition was never correctly diagnosed and not properly treated. After his problem got worse, we were really lucky to find Dr. Kehua Li at the Jefferson Dermatology Associates to treat him. Dr. Li made a quick diagnosis and prescribed medication that my son took for a month. His skin problem (infection) was finally eradicated and it was such a great relief! It is often frustrating for patients to be told that this disease has no cure, or that disease has unknown causes. It was truly a blessing to find a doctor who not only was able to decisively diagnose the disease, but also effectively cure it! We are deeply grateful to Dr. Li.
