Philosophy of Care
“I am extremely passionate about what I do and understand what my patients are going through, as I, too, was once a patient. My patients can expect to have positive, genuine interactions with me. I am very down-to-earth and dedicated to educating my patients and giving them honest advice based on their particular social or financial situation so they can make the best choice for themselves."
