Dr. Ballester-Fiallo, is an excellent Doctor. She is patient and kind and if I ever have any questions, she will answer them in a timely manner. I have been her patient for over 10 years and I have never had any issues or have I ever been displeased with her performance with me, I would truly recommend her as I have in the past.
