I am so grateful to Dr. Gillego for her knowledge, professionalism and kindness. I told her from the beginning that she was a second opinion, recommended by a friend; her office was out of state and too far for more than a consult. Still, she spent a lot of time with me, encouraging me to ask questions. After my surgery, Dr. Gillego called me to learn about my recovery. A dedicated surgeon who genuinely cares for each person's well-being, I highly recommend her.
