Our Hamilton Blvd driveway will be undergoing repairs from Wed Oct 7th - Sun Oct 11th. During this time, patients will not be allowed at that location for appointments or retainer/aligner pickups. Dr. Molly Kopf's patients normally scheduled at Hamilton on Thursday will be moving to our Dakota Dunes office (see the address at the bottom). Our team has attempted to contact those patients and most have been notified, but if you are unaware of this change, please call 712-258-0501.

There will be a receptionist at Hamilton to answer phone calls for the days that we're under construction. We apologize for the inconvenience, but it will be amazing to get the pothole fixed before winter!
