Dr. Cross has done such a fabulous job in the 8+ years I’ve been his patient, it leaves him with very little work to do on me these past few years. I appreciate how he embraces and has mastered cutting-edge technology. It’s also comforting that he remembers minor details about the condition of my teeth without even having to refer to my chart. The girls at the front desk have an equally impressive memory and are so sweet and friendly.

~ Happy Patient
