Meet our doctors
Dr. Olga Kats | DMD, MS
Dr. Kats’ family settled in Chicago when she was seven years old. She found a love of dentistry early in life after her own orthodontic treatment. She decided to attend the University of Illinois at Chicago for her undergraduate degree while she worked at an orthodontic clinic. Dr. Kats continued with her graduate work at University of Minnesota where she also did her orthodontic residency because she was impressed by the school’s focus on innovative technology and the future of orthodontics.
She prides herself on her desire to keep learning what is new in orthodontics and her ability to build a rapport with patients, something she considers important to the practice. Dr. Kats feels at home at Orthodontic Specialists of Lake County because of their patient-centered approach and commitment to embracing the latest innovations in orthodontic treatment.
When she is not treating patients, Dr. Kats enjoys spending time with family and friends, she loves to be active and enjoys outdoor activities like rollerblading and hiking. She also loves to try new restaurants and travel.
Dr. Terry Sellke | DDS, MS
Born in Chicago, Dr. Terry A. Sellke is a native Illinoisian. His fervor for Illinois extends to his academic background, having graduated from University of Illinois for his bachelors degree, for dental school, for his orthodontic training, and even his masters degree.
That is not, however where it ends. He teaches orthodontics, and has been a masters thesis advisor in the department of orthodontics for over 30 years. He holds the rank of professor, was co-director on the clinic, and earned the “master clinician” title.
Dr. Sellke taught more than 20 area orthodontists how to straighten teeth. He lectures domestically and internationally on clinical orthodontics as well as another of his passions, applying business principles to the practice of orthodontics.
Other affiliations and accomplishments include serving on the board of directors of the Illinois Orthodontic Alumni Association (26 years), the Lake County Board of Health (16 years), the board of the Foundation for Orthodontic Research (20 years). He served as the president of each organization. Dr. Sellke was elected to the American College of Dentists by his peers and has been a reviewer for the American Journal of Orthodontics for many years. He has published dozens of articles on orthodontics in professional journals worldwide. His text on the Bioprogressive Orthodontic Philosophy has been translated into four languages.
Dr. Sellke lives in Libertyville. His passions outside of orthodontics involve either mountains or the beach. He loves golfing, skiing, snorkeling, sailing and working. (He is a workaholic who loves orthodontics!) He is no good at tennis. Dr. Sellke has two children named Kirk and Kristin, and he loves to spend time with his 3 grandchildren, Gracie, Maddie and Clyde.
