Tawnya RDH, BSDH

Tawnya has been a hygienist for 17 years and in the dental field for a total of 25 years. Two of her favorite things about being in dentistry are helping her patients become knowledgeable in oral and physical health as well as creating a good work relationship with them.

Tawnya was born and raised in Tacoma, Washington. She has spent the last 19 years in Illinois and recently moved to Arizona in December of 2019. She has 2 sons and has an 18 month old granddaughter. When not at work she enjoys cooking, baking, and outdoor walks with her dogs and husband.


Jen has been in dentistry for 22 years and 12 of those as a hygienist. Her dedication to dentistry has made her mission to educate and teach others the importance of oral and total body health using the tools and knowledge that she has gained over the years.

An Arizona native, she has 3 siblings, 1 older brother and 2 younger sisters. She has a great husband and three children that keep her on her toes. Passionate about healthy living and helping others, she spends time with family, in the great outdoors, and with animals of all kinds.

Kelly – Office Manager

Kelly has been in the dental field for 25 years. In high school she was given the opportunity to have hands on learning in several healthcare fields and ultimately chose dentistry. After choosing a career in dental, she spent her first 8 years as a dental assistant and from there moved to the front office, which is where you will find her here as our office manager.

Originally from Michigan, she moved out here in 2003 with her husband.  She has two sweet daughters who are 10 and 13 and also has 3 dogs. Kelly enjoys traveling, hanging out with friends and family, snowboarding, and being a soccer mom.

Kimberly – Patient Treatment Coordinator

Kimberly has been in the dental field since 1979. She enjoys helping people achieve healthy beautiful smiles.

Growing up her father was in the United States Marine Corps and she lived many different places, her favorite by far was Hawaii. She absolutely loves the beach, going to art shows, attending music concerts, and cooking.

Taylor – Recare and Patient Communications Coordinator

Taylor started in the dental field 4 years ago. She had a great family dentist for 25 years and decided that dental is where she is most comfortable.

She attended Northern Arizona University and Glendale Community College for several years working towards a degree in Wildland and Fire Science. Since then though, she has decided to pursue a degree in Business and Agriculture, as she looks to move to Montana with her husband and 3 dogs to run cattle and ranch.

Tiffany – DA

Tiffany has been in the dental field for three years.  She started in an oral surgeon’s office at a front-office position and has worked her way towards becoming the dental assistant she currently is here with Mettler and Griego Family Dentistry.  As a child, she loved pulling her friends and siblings loose baby teeth out.  She really takes pride in the comfort and care she gives to our patients and in helping them achieve their healthy smile.

Tiffany is an Arizona native and has two beautiful boys.  She enjoys spending time with them, being outdoors, sports, cooking and baking, and lots of laughing.  She has also been a recreational soccer coach for the last 10 years.  She studied photography and fine arts in college and still practices her photography to this day.

Jenny – RDH

She knew early on in high school that become a hygienist is what she wanted to accomplish.  With a love for the outdoors, she moved up north and attended Northern Arizona University where she received her Bachelors of Science in Dental Hygiene.

She is a traveler at heart and is blessed to have been given opportunities to combine her passions of seeing the world and improving smiles and meeting new individuals.

She continues to educate herself to provide the proper up to date knowledge for her patients and work to fulfill their needs as their hygienist.

We would love to be your family dentist!
