Diana – Registered Dental Hygienist

Now I get to apply my love of technology and teaching to patient education.”

As a hygienist, Marina is always looking for different ways to increase her knowledge base and share it with her patients.  And since a mouth is an entry point to the rest of the body, many of the problems can be treated and, possibly, eliminated through a proper assessment.

You can always expect to receive great care when you are in Marina’s chair.
