I have proudly been an SDS customer for more than 20 years. Our multi-office group practice, Dental Specialists of Central Florida, purchased SDS Chairs when we first started, and we upgraded to new SDS chairs and units as their products continued to improve when we modernized our 8 clinics in Central Florida. I taught at Jacksonville University School of Orthodontics which also has all SDS chairs and units. Then I moved to Atlanta to open the Georgia School of Orthodontics as the first Clinical Director. When building out our two Atlanta locations, we purchased all SDS chairs and units for the school. In group practice and orthodontic schools, we treat a larger than normal volume of patients. SDS was very dependable and easy to maintain. Our family HIGHLY recommends SDS!
