    How was your appointment with Dr. Ong?

    Nov 29, 2021
    Dr. Delphine Ong, my oncologist, who came highly recommended, is so knowledgeable and professional, yet very personable and caring, even showing interest in family pictures. Her exams were thorough. She always took time to answer all of my many questions, and those of my family members, whom she patiently included in FaceTime, phone conferences, and in person. She and her nurse, Elizabeth also worked hard behind the scenes as patient advocates. Dr. Ong continues to be an outstanding advocate on behalf of her patients, giving complete exams, showing compassion, working in our best interest, encouraging us, and explaining and clarifying treatment. Her nurse Elizabeth has also been a valuable source of information, including a speaker phone call to my hospital room, in which she answered my questions and those of my family. She also has the important role in helping Dr. Ong gain insurance coverage for important consultations and other needed grants for expensive chemotherapy treatment.
