Erika E. - lead Dental Assistant at Sierra Oaks Dental Sacramento

Erika E. — Lead Registered Dental Assistant

My job entails leading the team of dental assistants. I do many things from assisting the doctors with patient visits and treatment, helping with sanitation of dental tools, scheduling assistants with doctors and patients, ordering supplies, and assisting the front office when needed.

I began working with Dr. Kim and the Sierra Oaks Dental team in October of 2017. My career in the dental field started in 2004 here in Sacramento. My dental education came from hands on training with Pacific University while working in Sacramento.

One of my favorite parts of the job is working with amazing patients and team members. We’re really lucky to have such a great team of hard workers here. Everyone supports each other and we’re quick to lend a hand when someone’s in need.

This office is in line with my professional goals because Dr. Kim has so much knowledge to share and I’m always eager to learn more, whether it’s through continuing education courses or in house workshops. I love working for Dr. Kim because we all strive to be the very best and provide the best dental care to our patients.

I have a son at home that I love providing for and caring for. I also enjoy being outdoors when I can and taking my son around Sacramento. My husband enjoys deep sea fishing, and occasionally I’ll go with him on a trip, which is always a treat.

This office is unique because of our new patient experience that utilizes the co-diagnosis process that allows the patient to pick which treatment fits them the best. We acknowledge that patients have different treatment expectations for different reasons.

José believes that being an Expanded Functions dental assistant allows the dentists to be available to see more patients since he is able to step in and finish dental procedures. He enjoys the great teamwork and family atmosphere at our office.
