Dr. Robert T. Cassens has returned to the office!

It is with absolute joy we share the news Dr. Rob is now treating patients during the morning office hours 3-4 days a week. While Dr. Cassens hasn’t returned full time, our office continues to operate a full time schedule for all services. In addition to Dr. Samantha Arnold on Tuesdays and Thursdays, we have welcomed Dr. Ashley Nowdomski. Dr. Nowdomski comes extremely qualified and is currently scheduling Mondays and Fridays. We understand the importance of continuity, not only in level of care but also in personnel, and truly are working to find the best long term arrangement for our existing patients, new patients and staff. It is our priority to provide our patients with the level of service they’ve become accustomed to, and we sincerely appreciate your patience as we work through this process. Should you have any questions or concerns, please do not hesitate to bring them to our attention.

If you are experiencing any dental issues or it is time for your regular cleaning and checkup, please contact our office, and we will be happy to get an appointment on the books. Should you have an existing appointment which needs to be rescheduled, please contact our office at your earliest convenience. As is customary, reminders will be sent for existing and newly scheduled appointments via text.

We are extremely grateful for all of the support, encouragement and prayers for Dr. Rob and our family. While Dr. Cassens will continue to undergo treatments, thus far he has had no complications and has received encouraging updates from his physicians. In fact, you might even catch him out enjoying a long bike ride or golfing!
