Dr. Feder has been my dentist since I was 5. He's kind patient thorough experienced and efficient. I had a few cavities as a kid and of them only one filling had to be replaced because the filling deteriorated. I've never had secondary cavities; once he fixes them they're set for life. That's over 20 years! I went another 10 without any cavities and I attribute a lot of that to Dr Feder's guidance. I have tried many other doctors because Dr. Feder does not accept the kind of insurance I have, but I still end up back with him. He's worth every penny. I highly recommend doctor Feder.
