Dental Hygienist

Hi, I’m Sandie, a dental hygienist with Dr. Williams since 1995. I am a graduate of Northeast Wisconsin Technical College (NWTC) and have been a member of the American Dental Hygiene Association since 1984. Staying abreast of current trends and research in the dental industry is very important to me. Since working with Dr. Williams I have attended many continuing education meetings, learning new ways to enhance patient experiences.

I enjoy the benefits of working with the advanced technology we have in our office and watching patients receive better treatment because of it. For example, many of our patients have said they like the benefit of CEREC crowns offered at Sierra Dental because everything is done in one visit without the need for temporary crowns. Additionally, I take great satisfaction in seeing improvement in a patient’s dental health and self-esteem after going through our periodontal program.

Having worked with Dr. Williams for almost 20 years, I’ve gotten to know many of our patients very well and have become personal friends with many. It’s fun to run into clients and their families at the mall or at sporting events in and around the area and catch up on what’s new and exciting!

As a Wisconsin native, I enjoy spending time outdoors. My husband and I enjoy boating, fishing, and packing in a little traveling every year. Our daughter, along with her husband and two grandsons live in the area and we love spending time with them.

It is my hope you feel welcome and comfortable in our office and that our staff will be able to assist you with any of your dental issues or concerns. 


Dental Hygienist

Hi, I'm Natasha, one of Dr. Marty's hygienists. I have been in the dental field since 1996 and employed at Sierra Dental since 2004.

Our office really does work at making your experience with us the best that it can be.  All of us here enjoy Dentistry and get along with each other.  We have an office of great personalities, we care about you and have up to date technology that allows us to make You our priority!  Continuing education is a big part of what we believe in and do.  I love being a hygienist and find it to be an awesome career fit for me.

I enjoy living in Wisconsin and all its seasons. I love to read and always have a book going.  My boyfriend and I enjoy hiking, rollerblading and taking weekend getaways. We both love food and enjoy cooking creative meals!  During the summer I spend a lot of my time with my parents who come up from NC.  My family and friends are a huge part of my life and who I am.

Have a great day and look forward to seeing you in our Green Bay dental practice!


Dental Assistant

My name is Ashley, I have been a part of the Sierra Dental team since 2008. I work chairside with Marty as his dental assistant. I enjoy being part of the family here at Sierra Dental. I was born and raised in Marshfield, but have been living in Green Bay since 2007. I am married to Ryan and we have 3 beautiful children. We enjoy camping, fishing & waterparks. I look forward to meeting new patients every day and help make dentistry fun.


Hi, my name is Jessica and I have been the Financial Ambassador at Sierra Dental since July 2014. I enjoy getting to know our current patient and welcoming new patients into the office. I am here to help patients understand their insurance policies and their financial obligation for their dental treatment. I take pride in being able to answer questions that patients have regarding their treatment whether it be insurance, cost, or scheduling.

I have worked in the dental field for 6 years as a scheduling and financial coordinator. During that time I have worked with dental insurance companies and helped patients learn more about financial tools to help them afford their dental treatment.

I've been married since 2009 to my wonderful husband. Since then we have welcomed our son Jackson and twin daughters Claire and Violet into our family. I enjoy watching movies, camping, and spending time with my family and friends.
