Dear Patients:

I am excited to announce that after years of solo practice, I have decided to partner with a group of doctors led by Dr. Kristine Kobayashi and Dr. Anna Pennino.  Together, we will lead our practice to new heights and we welcome you to come along for the adventure.  I take this opportunity to personally thank you in advance for your kind support of our new professional partnership.
