Dr. Clifford not only is an exceptional dentist but his practice is state of the art. He and his staff are friendly, accommodating, never keep me waiting and have given me paralleled dental care for over two years since moving to the Phoenix area. I give them 5 stars PLUS. I highly recommend Dr. Clifford for everything from regular cleanings to fillings, to root canals and crowns... all work he has performed beautifully for me.
