Meet Dr. Anthony Harwell

Hi there! I’m Dr. Anthony Harwell, and I’m so glad you’re here. I was born and raised in Amarillo and proudly graduated from Amarillo High School in 1988. My orthodontic journey started early — really early — as a second-grader helping out in my father’s orthodontic practice.

After spending 25 years working side by side with my dad, I eventually took over the practice, continuing a legacy built on kindness, dedication, and truly caring for patients. Today, I’m honored to carry that same patient-first philosophy forward at Harwell & Cook Orthodontics — and to help create smiles I know my father would be proud of.

Dr. Harwell’s Education

Dr. Harwell earned his Bachelor of Arts in Mathematics from Vanderbilt University before completing his Doctor of Dental Surgery degree at Baylor College of Dentistry in Dallas, Texas. He then pursued advanced orthodontic training at the University of Texas–Houston Dental Branch, where he earned a Certificate in Orthodontics and Dentofacial Orthopedics along with a Master of Science degree. His extensive education and specialized training reflect a lifelong commitment to excellence in orthodontic care.

Meet Dr. Tanner Cook

Welcome! I’m Dr. Cook, and I’m so glad you’re here. I grew up in the small town of Meers, Oklahoma, where I first learned the value of close-knit communities and genuine connections. I was drawn to orthodontics because it blends science and art in a way that truly changes lives — helping people become their best, most confident selves.

I’ve always been especially passionate about working with adolescents and making a positive impact during such an important stage of life. I joined Harwell & Cook Orthodontics in 2014 after feeling an immediate professional connection with Dr. Harwell and discovering we shared the same patient-first philosophy. Together, we’re committed to helping patients smile out loud, gain confidence, and let their personalities shine.

Dr. Cook’s Education

Dr. Cook earned his Bachelor of Science in Chemistry and Biochemistry from the University of Oklahoma before continuing at the University of Oklahoma College of Dentistry, where he received his Doctor of Dental Surgery degree. He stayed in Oklahoma to complete his orthodontic residency, earning both a Master of Science degree and a Certificate in Orthodontics in 2014. His extensive training combines science, skill, and a love for creating confident, beautiful smiles.
