I am very, very happy with Dr. Kesten's services. I previously was a patient of his partner, Dr. Fellman, when they were in DC, and I shifted to Dr. Kesten them he went into sole practice in Chevy Chase. Dr. Kesten did my last crown, and was very, very patient and persistent in getting it just right when I was having trouble adjusting to the new crown. He is easy to talk to, very pleasant and funny, and an all-round great guy. His office staff are also pleasant to deal with and billing has never been a problem. I highly recommend him for both routine preventive care and non-routine procedures. I don't think you'll be disappointed.
