We feel that even though we can't get in to see her very often, and mainly our provider is Urgent Care, Dr. Ball is part of our family!!! That's the way she treats us, that is her concern for us, that is her going over and above in helping us in getting our medical needs ready as we travel for our work, and on and on. We could never say enough about her. We are fortunate to have had her in our lives since we moved here! She is the best provider we have ever had in our adult life, seriously.
