Dr. Debra Cook

Being an Orthodontist is a fun adventure! I Love the challenge of fitting teeth together and getting to know the people behind the smiles! When you have an appointment at our office, I make sure to give you my undivided attention to go over all your questions and give you the very best treatment.

School / Education:

I completed my undergraduate work in Biology at California State University, San Bernardino. I received my D.D.S. degree from Loma Linda University School of Dentistry, graduating at the top of my class and distinguishing myself as a recipient of the California Dental Association Scholarship Award and as one of only a handful to be selected to Omicron Kappa Upsilon (Phi Beta Kappa).
