Hello! My name is Mary. I graduated from Concord in 2000 and while in school got a job at a pediatric and orthodontic office. I enjoyed working with kids so much I decided to stay in orthodontics. I have had the pleasure of working with RMO, a local orthodontic manufacturing company, training orthodontists all over the world! My hobbies are anything active. My family and I love to be outside and busy. My second passion is cooking – I was a semi-finalist for Hell's Kitchen and Master Chef. Third time's a charm – we will all see! Thanks for your interest and I look forward to helping you achieve a beautiful smile.
