The Personal Narrative

Roots in Idaho

Roots in Idaho

Dr. Holyoak grew up in Burley, Idaho, where his parents were educators who also ranched and farmed in south central Idaho. The combination of teaching and working the land shaped his temperament, patient, practical, and unhurried.

Dentistry runs in his family: he has two brothers who practice dentistry in the valley, and his own household has continued the tradition. Both of his sons became dentists, and both of his daughters became dental hygienists. Dinner conversations at the Holyoak family table have, for decades, drifted naturally toward bonded composites, periodontal protocols, and the curious resilience of the human tooth.

Outside the Office

Dr. Holyoak and his wife Jean live a full life outside dentistry. He spends time with his children and grandchildren, tends to his horses and mules, and works on his small farm in Mesa.

Background & Expertise

Half a century of clinical experience

Combining rigorous academic training with five decades of hands-on practice.

Premier Training

A BYU alumnus, Dr. Holyoak graduated from Oregon Health & Science University (OHSU) in 1974, a top-ranked institution that provided a rock-solid foundation in restorative dentistry.

Senior Dentistry

With 50 years of caring for Sun City and Peoria patients, he has mastered the complexities of senior care, from medication-induced oral changes to the long-term monitoring of periodontal health.

Technology Filter

He adopts what improves outcomes, such as digital radiography, and declines what is mostly marketing. "Does it actually help the patient sitting in this chair?"

On His Patients

Dr. Holyoak, in his own words
My patients have an honesty, integrity, and appreciation that can't be found anywhere else.

His approach

Philosophy & practice

An independent practice in a corporate era

Many practices that look independent are owned by national chains or private-equity groups operating under quiet management agreements. Dr. Holyoak chose not to go that way. Copper Sky Dental remains locally owned, which means the dentist who recommends a crown is the same dentist who places it, and no spreadsheet at a regional headquarters is dictating how many procedures need to happen this quarter.

That independence is the reason he is comfortable offering free second opinions on treatment plans patients have received elsewhere. Sometimes the recommended plan is exactly right. Sometimes a less invasive approach will work. Patients are entitled to know which, and they should not have to pay for that conversation.

How he approaches senior dental care

For seniors, the right answer is often not the most aggressive one: watching a tooth, a simpler restoration, or deciding together which teeth are worth saving. Patients on fixed incomes especially appreciate a dentist who will tell them the truth and will not push procedures that do not deliver value.

Mentorship & continuity

In recent years, Dr. Holyoak welcomed Dr. Lisa Kubik into the practice. He introduced her to longtime patients personally, vouched for her judgment, and made room for her to develop her own clinical voice, so the standard of care he has built over 50 years now comes from two dentists who share it.
