Hello, my name is Sandra Marquez.  I was born in Mexico but have live in arizona for 20+ years.  I am happily married and I we have two kids and three dogs.  on our free time we enjoy watching movies, walking the dogs, bicycle rides and the most important spending time with the family.  I love been a dental assistant, the best part helping people get the smile they want.  I been with sierra since 2004 and hope to continue seen many more smiles.  


At Sierra Family Dentistry, our team strives to provide a lifetime of healthy oral care for each of our patients, and I feel very fortunate to be a Dental Hygienist on this very caring and kind team! I aim to provide gentle and thorough care. I listen to each patient to determine his/her desired dental care and to help each of them discover how they can obtain optimal oral health. My favorite thing about practice dental hygiene is being able to guide my patients to relate how their dental health impacts their overall health.

I have been a Dental Hygienist since 2003 when I received my Associates of Applied Sciences from Phoenix College in Phoenix, Arizona. I also have a Bachelor’s of Science in Education from Northern State University in South Dakota, where I grew up with my large family on a farm and ranch. In my free time, I can be found spending time with my two sons and my husband, usually doing something outdoor and caring for our pets (a goat, cat, dog, and chickens).


I’m an Arizona native. I graduated high school in Gilbert, AZ, attended Chandler Gilbert Community College, and went on to get my Associates in Applied Science – Dental Hygiene at Carrington College in Mesa. I enjoy being part of such a caring, uplifting, and passionate team here at Sierra Family Dentistry. The field of hygiene is always growing and changing, and that’s why I love being a part of it! In my downtime, I keep busy with my two children and husband. I’m a dog lover, green tea drinker, and a vintage décor collector.


My name is Jackie, and I have been in Dentistry since 2004. I have 3 wonderful children who keep me very busy. We enjoy softball and weekends filled with friends, family, hiking and barbeques. Sierra Family Dentistry is my second family! We are excited to meet you and make sure you are comfortable at your dental home.


Bethany Trim is one of our Dental assistants and has been with the Sierra team for three years. She graduated from the American Institute of Dental Assisting in 2013 and plans to further her career by pursuing Dental Hygiene. In her free time she prefers to be outdoors either hiking, camping, or biking with her husband and two dogs. 


Ashley is a proud Alumni of Northern Arizona University’s Dental Hygiene Class of 2005. Shortly after she earned her Bachelor of Science degree in Dental Hygiene, she found her “work family” at Sierra Family Dentistry. Over a decade later, she is still excited to work with her dental family. The team continues to passionately provide exceptional dental care to patients whom they serve on a daily basis. Ashley’s favorite part about her job is connecting with patients and enjoying their many touching stories, jokes, journeys, children, adventures and antics (all while providing them with quality preventative hygiene services and education)!

Outside of the dental world, Ashley’s interests include spending as much time as possible with her husband Oliver, son Dominik, and rescue pup Oden! They are often found outdoors, hiking, fishing, camping, swimming, traveling and scuba diving… enjoying the adventure called life!

Hello, my name is Annette Duchene. I am the mother of two wonderful boys, one sweet little puppy and two silly cats. For fun we enjoy the outdoors such as fishing, hiking, and camping.  I love doing what I do, and that's to help others love their smiles. Seeing my patients reach their goals and achieve a happy healthy smile is what keeps me coming back to work every day!

I have been a dental assistant for 10 + years now and though I may be new to the team at Sierra, I have known and worked with this great team for 3 + years. Therefore, I am not just lucky but happy to call them my dental family. I see my job like the story of the star fish. Even if I can't make a difference to every starfish, I can make a difference one starfish at a time and with this amazing team we strive every day to do just that. By helping more people and making a difference, not just in their smiles but also to overcome their dental fears and challenges that stand in their way of reaching their goals.
