I have been a patient of Dr Delli Colli's for 21 years and until that time had dreaded twice yearly cleanings. Now I actually look forward to dental visits. The entire staff is friendly and Dr D is so gentle that I don't even feel the novocaine shot. I have had several crowns made and no one can even tell that they are not my original teeth. I have recommended Dr D to about 15 friends over the years and all of them still thank me for sending them to him.
