When you walk into Dr. Keen's office, the first person you'll meet is Michelle Ednilao. A native of El Cajon, she has worked with Dr. Keen since 2000 and has worked in the dental field since 1989. A friend's terrible toothache inspired Michelle to begin studying dental health, and she hasn't looked back since.

Nancy S.


Hi my name is Nancy Saucedo. My career in the dental field began over 20 years ago as a dental assistant in the U.S. Navy. Dentistry fascinated me, so I decided to further my education and obtain my degree as a dental hygienist at Loma Linda University. I love the work I get to do, and educating my patients is one of my passions. The most important people in my life are my husband, our two daughters, and our two dogs. We enjoy volunteering at our church on the weekends and always find time to cheer on our San Diego Padres.
