I love being an orthodontist! While the art and science of orthodontics is what initially drew me to the profession, the most rewarding part that keeps me passionate about it every day is the opportunity to be a positive influence in my patient’s life while helping them create a beautiful and healthy smile to last a lifetime

I feel so blessed to be an orthodontist in Southern Illinois. At Kevin Cook Orthodontics my staff and I are dedicated to providing you with an outstanding experience visit after visit. We aren’t satisfied with just OK — we want to be a positive influence in the lives of our patients and make orthodontics a wonderful experience for them. You can count on our whole team to be fun, outgoing, and friendly at every visit.

  • Great Experience
    Went in for a free consultation for adult Invisalign...staff was very friendly and informative of what all the treatment would consist of and was even willing to accept a competitor's coupon. Not to mention their lobby was so beautifully decorated and peaceful that I wished I had longer than a 2 minute wait to enjoy it. Will definitely be starting treatment with them soon!

  • Since day one, Dr. Cook and his staff have been amazing! The consultation was so informative. The day my daughter got her braces, they made it fun and exciting and complimented her on how good they looked. At every check up the staff was supportive and super friendly. My daughter left today with her braces off and was thrilled with her new smile. She's even more confident, if that's possible, and plans on smiling more with her teeth. Thank you to Dr. Cook and his staff more making this an easy, affordable and great experience.

  • Dr. Cook and His staff is amazing. They are always pleasant to deal with and can even make "grumpy" teens smile. Our son just got his braces off and we are so pleased. They keep the waiting room stocked for parents and have several activities going so a visit there isn't just another boring Dr visit. Keep up the great work!
