A friendly environment and a family environment is what our culture is and we hope we relay that to our patients. I want them to feel like this is their home away from home.

    Registered Dental Hygienist

    Registered Dental Hygienist at Lifetime Dental of Rancho Cucamonga. She earned her degree at the USC Dental School and has over 45 years of experience as both an Assistant and Hygienist.

    “Dentistry runs in my family, and I decided at an early age that I wanted to be a Hygienist. I try to provide patients with thorough and gentle gum care and always emphasize the importance of their home care as preventative action for further gum problems. I respect patients for their time and efforts and always strive to be on time and stay on time. I believe they deserve thorough explanations of all needed treatment and to be given adequate time to receive that treatment. I have loved my over 45 years and counting in dentistry. I started at the age of 12, helping in my father’s dental office, and now at the age of 57, I still love helping people achieve and maintain their periodontal health. The personal relationships I have formed with my patients over the years have enriched my life.”
