Dr. Ekaterina Slipacoff


Dr. Ekaterina Slipacoff, or Dr. Katie for short, obtained her ‘Doctor of Medical Dentistry’ (DMD) degree from Semmelweis University in Budapest, Hungary in 2011. She is a general dentist who offers a wide spectrum of services to her patients at Slipacoff Dental Centre in Sarnia. From the moment she graduated dental school, Dr. Katie has been very passionate about orthodontic treatment and what it can do to improve our overall health.

She has taken numerous postgraduate courses and mini-residencies to enhance her knowledge and skill in offering early interceptive orthodontic treatment to growing children and comprehensive orthodontic treatment with braces and Invisalign to teenagers and adults.

Dr. Katie incorporates a multidisciplinary approach to orthodontic treatment that she provides. She believes that a healthy jaw joint is just as important as having straight teeth and a nice facial profile. This is why she treats Temporomandibular disorders (TMD) in her attempt to develop a well functioning bite in addition to the beautiful smiles that she creates.

Dr. Katie and her team of dental hygienists and assistants are looking forward to helping you and your whole family achieve all of your orthodontic needs.

Dr. Katie feels truly grateful to be able to practice dentistry alongside her husband, Dr. Tyler Slipacoff, who she shares two beautiful children with (Sasha and Jake) and their English bulldog, Levy. In her spare time she loves reading, spending time with her family and focusing on a healthy lifestyle.
