    I was very pleased to have been assigned to the care provider i had. She was extremely knowledgeable and put me at ease. She was easy to talk with. I felt that I had known her before I met her. She went over all the aspects for my illness and gave me all the options of how to correct the illness. I would certainly recommend her to my friends.
