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 real thing. Not another scam office that just wants to sell you unneeded procedures. Hygienist, Trish is professional and thorough. Appointments are on time. They do not keep you waiting more than ten minutes. Usually take you right in. Front desk is also very accommodating and friendly...

My smile is brighter and better than ever and most everyone I talk to has commented on how great it is!

What a gift!! All I can say is thank you to all who were involved.

Devoted to a Lifetime of
Sound Oral Health

Dr. John Cross—our experienced cosmetic dentist—proudly offers these services, and much more, for you and your entire family.
