Meet Dr. Longos

My career in orthodontics has always been an incredible and exciting experience. I truly enjoy helping patients transform their smiles into something that will give them more confidence and self-esteem. It is a very rewarding feeling to know that, at the end of each workday, you have made a positive difference in the life of a patient.


I received my Bachelor of Arts and Doctorate of Dental Medicine from Southern Illinois University and was elected into the Phi Kappa Phi Honor and Omicron Kappa Upsilon Dental Honor Societies. During my formal education, I also received the American Academy of Oral Medicine Award.

I underwent my specialty training and received my Master of Science in orthodontics from St. Louis University. I was awarded the Kenneth J. Marshall Merit Award for being the class valedictorian in 1991. I complete continuing education courses regularly to stay informed of the latest in techniques and procedure innovations to provide my patients the highest quality of orthodontic care.
