Dr. Leung treats my son who has multiple autoimmune issues. She is the very best endocrinologist weve ever seen. Shes very kind and compassionate and she takes more time answering questions and explaining various issues and concerns than any other endo weve ever seen. She also really takes the time to listen to your symptoms and consider possible causes. If she cant figure someting out she will reach out to colleagues around the country in an effort to get answers. Ive found it to be etremely difficult to find a great endocrinologist, one that listens to you, explains the issues thoroughly and doesnt give up trying to find answers...Dr. Leung is the BEST!
