I have worked for Valley OMS since 2002. I began my career in the insurance department and in 2019 I transitioned to Office Manager.

Working for Dr. Schwarz for over 19 years has been such a blessing. The people I work with are like my second family.  It has been so rewarding to see our VOMS family continue to grow. The knowledge that Dr. Schwarz has is so valuable to our community. Our patients are loved and well taken care of by our whole team. I look forward to many more years with Valley OMS.

In my downtime, I love to read, watch movies & shows, and love to travel. I have 2 kids, Ryder & Courtney, and have been married to my husband Carlos for 12 years.

I’m a dental hygienist. I have been part of the VOMS team since 2016. I feel very blessed to be part of such a Wonderful practice and profession. 

Working at VOMS is like no other experience. I’ve had to transition from dental cleanings to preventive implant care and use of ND: Yag laser. My favorite part of working at VOMS is the patient care. I greatly enjoy helping transform patients’ smiles. Making sure each patient I see has a great experience makes all the difference to me.  

On my spare time I enjoy baking. My favorite cakes have got to be making Wedding and Quinceanera cakes. To me a cake is like my canvas where I can get as creative as the occasion calls for. I love paying attention to detail which I feel makes me a great baker and a great hygienist. I can’t wait to see you in our office.
