I have been involved with treatment from Dr. Long and his staff and they have always been very responsive to my emails and calls. Dr Long has provided excellent recommendations and follow ups to my treatments and I've had excellent results of my treatment. Dr. Long recommended a drug for my condition and my condition has markedly improved. He also has a follow up plan to my treatment. Dr. Long's staff has provided outstanding care to me and I am much appreciative and am lucky to have him as my provider.

He is a great doctor. Very kind and easy to talk to. He is really helpful and answers questions. I can tell he is honest and cares about my health and well being. I definitely feel very comfortable talking to him about any issues and when I have tons of questions, he is patient and always answers them all!! After going through about 4-5 other doctors, I'm glad I found Dr. Long and hope I never have to go to a different endocrinologist again!!
