RDA, Office Manager

staff donna

Hi my name is Donna. I’m a Registered Dental Assistant. I have been working with Dr Steve for 20 years as his office manager. It has been a very rewarding career, working with children and their parents. Watching them grow every year and becoming a part of our dental family is such a pleasure. My husband & I have been blessed with 2 married children & 3 granddaughters. I have been also blessed with the privilege of taking care of my Mom. We also have 4 dogs that weight 6 lbs to 40 lbs who rule our house and the smallest is the most demanding one.

Hi, my name is Jackie and I am originally from San Bernardino. I graduated from United Health Careers, San Bernardino (now Concorde Career College) in 1984 and received my RDA in 1986. I have been working as a dental assistant for over 30 years. I moved to Morongo Valley in 1997 and have been employed with Dr. Niethamer since 2000. Most of my career was assisting in general dentistry, but working with children is exactly where I need to be!
I have a son, Michael, who is a CSUSB graduate and a wonderful man in my life, Walt. We enjoy traveling to our “other home” in Italy, and spending time with family and friends.

I worked in a General Family Practice office my first three years in the dental profession and then joined a wonderful pediatric office in 1999 in Glendale.

All but three years of my dental career has been in Pediatric dentistry. When I am not working or with my husband Marcello, I am with our son Matthew who was born in 2003.
