Amy Mack, Registered Dental Hygienist

Amy Mack (Bracken) is going into her 23rd year in the dental field. After 12 years of dental assisting, front office and lab work, Amy completed her Bachelor’s Degree in Dental Hygiene at Northern Arizona University in 2003.  Working with disabled and special needs patients are challenges that she enjoys because it brings health, comfort and happiness to some who were previously not inclined to make dental visits.  Amy feels as though educating patients and families about their personal health and dental needs reduces fears and helps them taking an active part in improving upon their care from childhood to elderly. Laser assisted periodontal care is among Amy’s skills along with all other aspects of dental hygiene.

Raising her two daughters , who do everything from racing anything on wheels to 4-H, keeps Amy pretty busy. Family is always number one and feels blessed she can live in Kingman 40 years and be a part of their lives and support one another in careers and raising family.  She takes and active role in community including The Fight Against Violence in memory of Holly Mack which supports the Kingman High School Girls Golf, Kingman Aid to Abused People, and Grace Lutheran Church.

Heidi Riley, Front Office / Insurance & Billing 

Heidi has lived in Kingman, Arizona the majority of her life after moving here from Massachusetts as a child. After applying for what she thought was a receptionist position Dr. Kelly Bradley took her under her wing and trained her as a Dental Assistant. For a short while Heidi also worked in a Dental Lab before moving to Colorado. However she became homesick and came back to Kingman, Arizona and joined the team at Family Dentistry By Design and once again working side by side with Dr. Kelly Bradley.

After working as a Dental Assistant for some time Heidi progressed to the Front Office handling everything from answering any questions or concerns you may have as well as coordinating the administrative details, insurance, and many other tasks as they arise.  Heidi said that one of the most rewarding parts of her job is helping people overcome their fears and anxieties of both going to the dentist and dental procedures.
