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.

I feel comfortable and confident with my visits with Dr. Ball. I was concerned after Dr. Linda Lamm left her practice that I would not be able to find another provider who would listen to me and address my concerns, but we have been blessed to find Dr. Ball. Dr. Ball is also [person] Doctor and after multiple visists with other Doctors and Specialists Dr. Ball was able to diagose her with FLD. [person] now has also been diagnosed with stage IV metastatic cancer. Dr. Ball has been treating her and is always available to meet with her and family to discuss care and treatment. Our family cannot thank her enough.
