He was great! Took his time with the patient and explained. Asked if you had concerns or questions and he answered then where you could understand. but most of all the one thing that caught my attention,  at the end just before he exit, he would always say God Bless. That said a lot about the man he was. He has retired now. What a loss to the medical field
