I am our Patient coordinator. I am one of the first people to welcome new patient to our Practice. My background in orthodontics also includes being a Certified Orthodontic Assistant. How lucky I am to be able to follow our patients from the beginning to their end result of a glowing smile. I take special pride in keeping the team on time for your appointment. My priority is ensuring that our patients have a positive experience in our office.

I am married to pat and we have 3 wonderful children, Taylor, Colin, and Morgan. I enjoy spending time with my family and friends, going to movies, shopping and most of all, watching my children play soccer.

I am one of the clinical orthodontic assistants at Advanced orthodontics. I am a certified Dental Assistant and have been working in the orthodontic field for the past 15 year, with prior experience in both General Dentistry and Oral Surgery. The best part of my job is getting to know our patients and helping them feel comfortable with their treatment (always finding time for some fun along the way !). Assisting, patients educations and lab work are some of my responsibilities in our office .

My free time is spent with my husband jerry, our three awesome daughter, and our Boston Terrier “Ellie”. Much of our time is spent at our cabin in Northern Wisconsin where we enjoy snowmobiling, boating and just generally being outdoors. I also find time for volunteering for our church, doing a little jewelry making and of course….shopping.

I have had close ties with the Sussex area for many years with both work and my home. It has been my pleasure to continue working with this community by being part of the friendly , fun and very capable staff here at Advanced Orthodontics.
