    Dr. Pfister is an amazing dentist. He's very gentle, respectful, and very knowledgeable on most facets of dentistry. His staff is amazing too, they're always so nice to me and my children. He's an expert in ozone therapy and minimally invasive dentistry and preventative which basically means that if you want the best chance to have the least amount of dentistry done, you need to see him. My kid loves coming here, he can't wait for his xylitol (non cavity forming!) lollipop after his work is done. How many kids like their dentist?!?! BTW, I'm a dentist and he's the one I see, that should tell you how good he is.
  • Dentist Greenwood -  Star Reviews by Rachel D. I have been going to Dr. Pfister since he took over for Dr. Domb. I have nothing but great things to say about him. I feel he is fair, knowledgeable and genuinely concerned for his patients. His staff is friendly, professional and very helpful if you need to get in right away with a problem. ~ Rachel D.
  • Dentist Greenwood -  Star Reviews by Paula M. My husband and I and our 2 children have been going to Dr. Pfister for about 2 years and we could not be happier with the care we have received. What's important to me is that he is on the cutting edge of minimally invasive procedures. I worry about putting my kids asleep and using other drugs, and the long term impact of mercury. We've had a couple tricky issues and he's had a solution for every cavity, crown, etc. that has worked in our best interest. The computer programs he has used to show us our cases have been amazing to me, no other dentist I have been to has had this technology. Regarding his staff they are professional, cheerful, and knowledgeable, a great asset to the office. And the building itself is unique and beautiful. I would highly recommend Dr. Pfister to any friend or family member. ~ Paula M.
