Providing doctor-focused, personal care to each patient

Welcome to Peterson Orthodontics, Ltd

Peterson Orthodontics has built a reputation over the past 20 years as being a respected orthodontic care provider serving the Chicago suburban areas on the north and northwest sides. Our goal is to provide you with the highest quality of orthodontic care in a friendly, comfortable environment.

As an experienced orthodontist in the Chicagoland area, Dr. Robert Peterson has helped patients of all ages achieve a straight, beautiful smile. With an emphasis on conservative, non-extraction orthodontic treatment, Dr. Peterson uses growth and development appliances to prevent extractions whenever possible.

We want you to be informed about all your orthodontic treatment options so you can make the best decisions about your health and well-being. During your initial exam, you’ll learn about all the treatments we offer, including traditional metal and clear braces and Invisalign® clear aligners.

Please feel free to contact our Park Ridge or Wilmette orthodontic office with any questions you have or to request an appointment! We want you to be happy with your smile and when you look in the mirror, you’ll smile because you know you made the right choice going to Peterson Orthodontics for your orthodontic care.

Dr. Peterson was very thorough in explaining exactly what my son needed and what to expect. He is also very friendly which kept my son at ease. The office is a well-oiled machine. Everything about our visit was smooth and well-organized.


The staff were very friendly. Dr. Peterson was very kind and professional and explained things patiently. This is our second time visiting the dental clinic, and although we haven’t started my daughter’s treatment yet, my daughter is at ease and comfortable dealing with Dr. Peterson, so she’s looking forward to it.


My braces came off this week and my teeth are now perfectly straight and feel more comfortable in my mouth. I should have gotten braces years ago. I am very happy with the results!!!
