Diana understands how important it is to make patients feel comfortable and makes this her top priority. When she is not assisting, Diana enjoys being active both running and working out with her husband and dog as well as painting, reading, dancing and playing soccer.

Jessica Kuhn


Jessica has been working with Dr. Poncza for nearly a decade and has been at Smile On since before we opened our doors. With over 15 years of dental practice management experience she strives to make sure that each and every patient experience is as comfortable and pleasurable as possible. Together with Dr. Poncza and the Smile On team, Jessica prides herself on the relationships created over the years with our patients and their families, as well as with the Lakeview neighborhood and dental community. She regularly attends continuing education courses regarding both dentistry and dental sleep medicine to ensure that we are able to provide our patients with the most current and up to date patient educational tools and insurance awareness. When she’s not busy at Smile On, Jessica enjoys traveling, attending the theater, trying new restaurants and just hanging out with her nephews.

Eboni McKnight


Our newest dental assistant, Eboni, is a Chicago native and has been a member of the Smile On team since September 2016. Hardly a year here with our office, Eboni compliments our professional environment and adds just enough energy to make your visit a little more pleasant. Eboni loves meeting and helping patients, assisting Dr. McDonald and promoting good hygiene habits almost as much as she loves Beyoncé! When she’s not busy at work, you can find her at the movies, exploring the city or checking out new restaurants all while keeping her Smile On.
