Kristina Sakas Katz, DDS, MS

Dr. Kristina Sakas Katz has been a lifelong orthodontic learner. Beginning at 10 years of age, she could be found shadowing her mother, Dr. Jacqueline G. Rosen, at the office. This early childhood interest developed into a lifelong passion.


Dr. Sakas Katz received a doctorate of dental surgery from the Herman Ostrow School Of Dentistry of USC at the University of Southern California. Graduating in the top of her class, Dr. Sakas Katz went on to attend USC's orthodontic residency program where she earned a Master of Science degree in craniofacial biology and a specialty degree in orthodontics.


Dr. Sakas Katz is a board-certified orthodontist, which means she has voluntarily gone through additional hours of preparation to demonstrate the judgment, skills and knowledge required for providing the highest level of patient care. Achieving board certification is the last step in a long and intensive educational experience to ultimately provide excellent patient care.


In her free time, Dr. Sakas Katz loves to travel and learn about different cultures. She also enjoys cooking, hiking, biking, skiing, listening to music and spending time with her loved ones.

While in dental school and in residency, Dr. Belavsky received awards for outstanding leadership, impressive scholastic performance, and compassionate patient care. In addition, his master’s thesis on plaque removal was published in the International Journal of Dentistry and Oral Science.


For nearly a decade, Dr. Belavsky was an Assistant Professor at the UIC College of Dentistry in the department of orthodontics. He now teaches at the Marquette University School of Dentistry in the Department of Orthodontics. In addition to lecturing on topics such as biomechanics and treatment planning, he also plays an important clinical role at the university by working with the residents on providing patient care.


Dr. Belavsky has also been heavily involved in local organized dentistry, and in 2022 began his tenure as the President of the Northwest Suburban Society branch of the Chicago Dental Society.


In his free time, Dr. Belavsky enjoys spending time with his family and with his wife, Ashley. Some of his favorite activities are cooking, watching movies, reading, getting outdoors, listening to music, playing drums, and traveling.
