Patient Testimonials

"I had an appointment yesterday with Dr. Nielsen for the first time. The weather detoured me and made me very late (about 20 or 30 minutes), but the staff still made grand efforts to accommodate me. It was also my first time having cavities filled, and while I chose not to have Novocain in the interest of time, there was still very minimal pain involved. I didn't realize having cavities filled could be such an easy process. I appreciate so much the excellent work that the staff did to keep my appointment despite my delay and for helping to make my teeth clean and healthy! Thank you so much. Dr. Nielsen is a great addition to the team. "   - Erin K.


"I recently started going to Dr. Powell since the location is closer to my home and very convenient.  The staff is thorough, friendly and courteous.  They made me feel comfortable right away.  My last appointment involved some small fillings and the replacement of an old silver filling, which made me very nervous and apprehensive due to pain I experienced in the past.  I quickly discovered there was no need for those past fears with the state of the art laser dentistry Dr. Powell used which left me pain free - what a pleasant surprise!  It was also impressive to see how efficiently Dr. Powell and his assistants work together.  I no longer fear these experiences and highly recommend Dr. Powell and his admirable staff for your dental needs. Thank you for putting me at ease Windsor Preventive Dental Care."   - Patricia C., Windsor
