I would HIGHLY recommend Dr Sleder. I have had several treatments done by Dr Sleder and they were all very successful! I did not have any anxiety , he is so pleasant I felt completely comfortable . His office staff is very friendly and I love the fact they make"reminder" calls to the patients. They handle insurance claims promptly which is very impressive these days! His office is not near my area but because he is such a good Endodontist I don't mind the drive at all!!! He's at least a TEN in my book!!
