Serving the Cupertino community
Cupertino is just one freeway exit south on 280 and roughly an 8-minute drive on Stevens Creek or Wolfe. Many of our Cupertino patients are referred by general dentists in the Stevens Creek dental corridor when a case needs a CBCT scan, surgical microscope, and dedicated endodontic specialist. We also see a steady stream of Apple, Seagate, and de Anza-area professionals who need an appointment that fits between meetings — early morning, lunchtime, or after work.
