How Do We Have Fun?

Dentists have lives too! When they’re not taking away the pain in your tooth our Endodontists relax in a variety of ways.
Dr. Marcks’ favorite hobby?
Fly Fishing of course!
When he’s not performing root canals he’s probably casting a rod into a beautiful river somewhere.
Giving Back
Since its beginnings, being involved in the community and giving back have been an important facet of Moreno Valley Endodontics.
To the Community:
With the help of their able and caring staff, both Doctors provide endodontic care for disadvantaged youth in their office for Project KIND, a local non-profit organization, on an ongoing basis.
To the Dental Community:
Dr. Marcks and Dr. Diaz are part time adjunct faculty members of the Endodontics Department of Loma Linda University School of Dentisty. They are clinical instructors on the endodontic clinic floor, alternating one morning a week throughout the academic year.
Our Mission
We at Moreno Valley Endodontics are committed to delivering the highest quality of endodontic care in a comfortable, friendly environment.
