    my first visit with Dr. Ling since he was referred by Dr. Jayani who has since left her practice at St. Jude. Dr. Ling communicated with me very well, he was clear and concise. He asked a lot if questions regarding my health status and was genuine with providing the best outcome for me. I felt very comfortable and was not put off with a standard protocal. Dr. Ling gave me good advise regarding discussing some other options with my primary care physician.
    This was my first time seeing Dr. Ling. He was very kind, knowledgeable, and comforting.
    This was the first time I saw Dr. Ling I thought he appeared to be very knowledgeable and professional However I was disappointed that he didn't have my prior medical file since I brought it to the first appointment and the doctor told me she was going to have it placed in my file.
    This was my first visit with Dr. Ling. He is easy to talk to about my condition and gave me detailed and understandable information.
    like this Dr very much and staff are really helpful and pleasant too
