Meet Our Team

The Staff of Dr. Allan S. Thomas DMD

Shayla Cawley | Treatment Coordinator

I have been in the dental field since 2013. I started out as a Dental Assistant, where I completely fell in love with Dentistry. After I got married to my husband Dan, I decided that I liked the business aspect, and started to migrate towards the front office.

I love my Job! I love waking up each morning knowing that I get to go to work and help change someone’s smile. I love the interaction I get to have with patients because I get to participate in the process of making treatment happen. Dr. Thomas is so talented and it really is an honor to work in his practice.

My husband and I live in Sandy and have 2 wonderful children and our dog, Barkley. We love spending time with our family and friends playing games, camping and traveling.


Tiffany Peterson Tiffany Peterson | Treatment Coordinator

I started my Dental career in an orthodontic office. I was working on a patient when his father (a dentist) came in to pick him up. We talked for a while and that night he called me and offered me a job. I have been working in dentistry ever since. I love it!!! It’s been 19 amazing years since I walked into the dental office and I haven’t had any regrets. (Well maybe 1, I should just be a dentist).

I am proud to say that I am a wife to the most amazing man. His name is Brian and we have been married 18 years. We have 4 beautiful children who put a smile on my face every day. My son Dallon is 15 and loves sports! Baseball is his true passion. Then come 3 girls. Asha is 12 and LOVES anything electronic. Izabel is 7 and is my social butterfly and my sweet Eva is 3. She is who really runs our house. We often call her “Eva Diva”. I feel very blessed to be a mother, I love spending time with my family.

I feel equally as blessed to have a job that is so rewarding. I was blessed to go to the Dominican Republic with Dr. Thomas to do humanitarian work. It changed my life for the better. Every day I have gratitude for my life and the country I live in. We are a blessed people. It is amazing to serve others, and put smiles on people’s faces.

Interacting with people is one of my favorite things to do, so I’m happy to be at the front desk at this fantastic dental office. I was born and raised in Provo, UT where I spent a lot of time dancing. While attending BYU, I have amazing opportunities to perform all over the world with the Ballroom Touring Company. In August 2017, I married my best friend and moved to Salt Lake City. We have such a blast watching and playing sports, being outside and just spending time with friends and family.

Ashley Castellanos | Dental Hygienist

I have always loved and been so curious about the dental field. I started off as an assistant working for Dr. Thomas and then later went on to hygiene school to continue my dental education. I was thrilled to continue working for Dr. Thomas as a hygienist and have loved every second of it. I love getting to know my patients and making sure that they not only get the best treatment but that they understand the importance of taking care of their oral health. I hope that I can help each of my patients maintain not only a healthy smile but also a happy smile! I was born and raised here in Salt Lake City, specifically in the Millcreek area. My husband and I currently live in Millcreek and we just love the outdoors. We love having the mountains and canyons so close to keep us healthy and active. A few of our favorite things are biking, hiking, and spending time with family.


Whitley Thompson | Dental Assistant

I have been a dental assistant for four years. I started working with Dr. Thomas in February of 2018. I grew up in a small town called Grantsville, but recently moved to Salt Lake City. I love dental assisting, it is very heartwarming to see people who are not comfortable with their smile become absolutely in love with it. I have a husband named Cory, we got married in September of 2016 and we are loving life. We love to go on adventures and we are both super nerdy. I really enjoy super heroes, Harry Potter, and have even played a few games of Dungeons and Dragons. I also love running and exercising.
