Meet Our Team

Dr. Jeffrey Spillers
Dr. Jeffrey Spillers was born in Casper, Wyoming, where he spent his early childhood with his identical twin brother and younger sister, before his family relocated to Reno, Nevada. He attended school from elementary through college in “The Biggest Little City,” complete with a bachelor’s degree in chemistry from the University of Nevada-Reno. Dr. Spillers was then accepted into the prestigious three-year program at the Arthur Dugoni School of Dentistry in San Francisco, California. He spent three years learning didactic and clinical dental work, as well as becoming involved in many other facets, including charitable work through the SCOPE program, and certification in Invisalign.

Upon completion of dental school, Dr. Spillers and his family relocated to Reno for a couple of years. Dr. Spillers gained the knowledge of starting up a practice, including office management, and exponentially expanded his clinical experience. He established a nursing-home program, providing dentistry to over one thousand residents at five of the local facilities. He gained extensive knowledge in geriatric dentistry, including denture fabrication. Dr. Spillers also became very involved in local business organizations, such as LeTip and the Chamber of Commerce.

At the beginning of 2013, Dr. Spillers and his family relocated to Tucson to join the iSmile family. He is constantly expanding his clinical knowledge with the help of implant and orthodontic fellowships through the company. He looks forward to serving the local community and establishing his roots in Tucson for a long time to come. While in dental school, Jeff married his college sweetheart, Stevie, and they currently have three beautiful girls. Dr. Spillers enjoys golfing year-round, discovering his new hometown’s beauty, and sharing dental stories with his brother, who is a dentist with the U.S. Navy.

Through his affiliation with Dental Associates, Dr. Stewart became the Team Dentist at the University of Notre Dame where he constructed custom mouthguards for the Fighting Irish Football Team and any other student athletes needing a mouthguard or emergency dental treatment.

Dr. Stewart became involved with the American Academy of Physiologic Dentistry and lectured at the 7th World Congress. He has had extensive training in the diagnosis and treatment of temporomandibular disorders both phase 1 and phase 2.

Dr. Stewart has a strong commitment to treating patients with Sleep Apnea and has devoted many hours to continue his education in this field.

Dr. Stewart moved to the Tucson area with his wife Katrina in 2018, and enjoys the beautiful sunsets, golfing and upland bird hunting with his German shorthaired pointer, Bixie in the desert.

Amy – Office Coordinator
I was born and raised in Southern California and decided to join the Navy at an early age. That created the pathway for my career in dentistry. I have a passion for dentistry and I love what I do.

I have 2 amazing daughters who I spend most of my time with. When I’m not working or with my girls, I play softball on a coed team, hike and travel as much as I can.

Maria – Front Office Coordinator
Maria lived in Willcox from the day she was born up until she decided to explore the dental field, 4 years ago. She moved to Tucson, obtained her Dental Assistant certificate and recently moved back to enjoy the company of her family and friends. Maria takes pride in learning something new everyday and taking care of patient’s needs during their visit.

When she is not working, she loves the outdoors, and spending time with family and friends.

Cressi – Regional Marketing Director – Arizona
Aloha! I’m Cressi, the Regional Sales and Marketing Director for iSmile Dental. I oversee the Marketing efforts for our 5 offices in Arizona.
I have been in the Dental field since 1985 and also have a background in Radio.
I moved to Tucson, AZ to be closer to my children and grandchildren after spending just over six years on the Big Island of Hawaii.
I love travelling to new places and seeing our beautiful country. I’m an avid photographer and had a successful photography business in Hawaii and had many of my photos published in local publications. Although I’ve accomplished many of my bucket list goals, like learning to fly a small plane…I still have many more to go. Next on the list is publishing my first book, due out before the end of the year 2017.
I look forward to watching the iSmile Family grow and be an active part of our many communities throughout Utah and Arizona.
