Dr. Klein is the best dentist I have ever seen on an emergency basis, and certainly the most thorough. He gave a complete exam, with x-rays, on a walk-in basis (as I came on advice of another patient). He refused to take payment, and made a sound professional recommendation on how I should proceed. He even offered to email my x-rays to my regular dentist. I was relieved to learn, quickly and painlessly, that the issue did not demand immediate care. I could not have been more impressed. I would definitely consider going back to Dr. Klein permanently, and I would highly recommend him. Truly awesome, both as a doctor, and a human being.
