Patients have become more than just patients in her eyes, many of them have become friends. The main reason she loves doing what she does, is to see the smile on our patients faces after not smiling for many years due to the smile they were never able to show. She is happily married to her loving husband Michael, with 3 boys. She loves animals too, not many people can say that they have a pet duck name Dwight, who lives in their home and travels with them.
