About Copper Sky Dental
Locally and privately owned since 1976 — not a corporate chain. Our dentists live in the community they serve, providing personalized care for adults and seniors across the West Valley.
Copper Sky Dental is a locally and privately owned dental practice — not a corporate chain. Located in Peoria on the border of Sun City, we are proud to serve adults and seniors throughout the West Valley with the kind of personal, attentive care that only an independent practice can provide.
Our dentists, Dr. Robert Holyoak and Dr. Lisa Kubik, live in this community and raise their families here. Dr. Holyoak has been caring for his neighbors since 1976 — nearly 50 years of building real relationships with the people he serves. When you walk through our door, you see the same trusted faces, not a rotating cast of corporate-assigned providers.
We take time to listen, explain your options honestly, and create treatment plans that respect your goals, budget, and comfort level. Whether you need a routine cleaning, dental implants, or anything in between, you will find a warm welcome and genuine care at Copper Sky Dental.
Meet Our Dentists
Experienced dental professionals committed to your oral health and comfort.
Dr. Robert Holyoak
General Dentist
Dr. Holyoak grew up in Burley, Idaho, where his parents were educators who also ranched and farmed in south central Idaho. Dentistry runs in his family—he has two brothers who practice dentistry in the valley.
After earning his undergraduate degree from Brigham Young University in Provo, Utah, Dr. Holyoak completed his dental education at the University of Oregon Dental School, graduating in 1974. He began practicing in Sun City in 1976 and quickly developed a passion for working with adult patients.
Dr. Holyoak and his wife Jean have built a family deeply rooted in dentistry—both of their sons are dentists, and both daughters are dental hygienists. With nearly 50 years of experience serving the Sun City community, Dr. Holyoak values the relationships he has built with his patients.
"My patients have an honesty, integrity, and appreciation that can't be found anywhere else."
Outside the office, Dr. Holyoak enjoys spending time with his family, tending to his horses and mules, and working on his small farm in Mesa. He is an avid outdoorsman who loves packing trips with his mules, hunting, fishing, and skiing.
Dr. Lisa Kubik
General Dentist
Dr. Kubik joined Copper Sky Dental to continue her passion for providing exceptional dental care to patients in Sun City, Sun City West, and the greater Peoria area.
Originally from Muskego, Wisconsin, Dr. Kubik attended the University of Wisconsin - La Crosse and initially pursued a career in personal banking. Her perspective on dentistry changed when she became an adult orthodontic patient and experienced firsthand the positive impact quality dental care can have on a person's life.
Inspired to pursue her new calling, Dr. Kubik moved to Arizona to attend the prestigious Midwestern University College of Dental Medicine in Glendale. After graduation, she and her husband decided to make Arizona their permanent home and have since welcomed two daughters and a son.
Dr. Kubik is dedicated to creating a comfortable, welcoming environment for all patients and takes pride in helping people achieve healthier, more confident smiles.
"I became a dentist because I experienced firsthand how quality dental care can change a person's life. I want to give that same experience to every patient."
