Nikki Favata is our Surgical and Patient Care Coordinator. She came to us in February 2018. Nikki is dedicated to making each patient’s experience a positive one, from beginning to end, and the level of customer service in addition to her dedication to our patients is extraordinary. Much of Nikki’s expertise came from working with her father, a local Tampa plastic surgeon, as a surgical coordinator and office manager. Her 20 years of customer service in the medical and educational fields are now invaluable to Dr. Castor’s practice.
