Meet Our Staff

Office Manager and New Patient Coordinator
Hello, it's nice to meet you! I am the office manager and new patient coordinator at our Frankfort office. I love getting to meet all of our new patients and seeing how the doctors interact with each patient to make their treatment a positive experience. I have worked in the orthodontic field since 1988, and loved every minute of it, especially seeing how the technology has advanced over the years. I am originally from Tinley Park, and have lived in Orland Hills since 1999. I have two beautiful children, Austin and Madison. When I am away from the practice, I enjoy watching my children participate in all of their various activities, and of course, shopping!

Marketing Coordinator
Hi, I'm Maggie! I work in marketing and appointment setting. I have worked in the orthodontic field since 2006 and at this practice since 2008. I enjoy working in orthodontics and especially getting to know the patients and their parents. I like being part of this team - their smiles, dedication to their work, and the quality they deliver makes each day a great day! I live in Frankfort with my husband, Craig, and our two children, Paige (who is very excited to have braces), and Joshua (who is somewhat interested in braces). I enjoy running and gardening in my spare time.

I am an orthodontic assistant here at Petty, Bielik and Burke. I started in 2007, and I consider myself lucky to work for and with such great people. I enjoy talking to my patients and finding out what their interests are and watching the progress of their changing teeth. Some of the things I do here are helping the doctors put on braces, change wires, take impressions, x-rays and photos. I also talk to my patients about the importance of keeping their teeth and gums clean and healthy. I enjoy working on teeth, it doesn't gross me out at all! When I'm not working, I like to spend time with friends and family. I enjoy going out to eat, shopping, playing games, listening to music watching TV, working on craft projects, and working in my garden.
