    My consultation with Dr. Foster prior to the procedure was simple and easy. She answered all of my questions and made me feel at ease. On procedure day, her entire team was flawless. Renee, Jessica, Estella, Earl, and Latisha were all outstanding in their separate roles but cohesively made my experience seamless. I appreciated their professionalism, knowledge, kindness, and performance. I highly recommend Dr. Foster and the crew.
