Meet Our Orthodontists

Dr. Anthony Harwell, Jr.

Dr. Anthony Harwell brings decades of orthodontic experience to his work at Harwell & Cook Orthodontics, where he focuses on helping patients build healthy, confident smiles through thoughtful, individualized care. Patients appreciate his calm demeanor, precise approach, and the time he takes to ensure every treatment plan is tailored to their needs, regardless of age.

Dr. Harwell’s connection to orthodontics began early, growing up around his father’s practice and learning firsthand the importance of consistency, compassion, and patient relationships. After spending more than 20 years practicing alongside his father, he continues that tradition today by blending time-tested principles with modern orthodontic advancements such as digital treatment planning and self-ligating systems to achieve comfortable, reliable outcomes.

He earned his Bachelor of Arts in Mathematics from Vanderbilt University and completed his Doctor of Dental Surgery degree at Baylor College of Dentistry. Dr. Harwell also completed advanced orthodontic training at the University of Texas–Houston, where he earned both a Certificate in Orthodontics and Dentofacial Orthopedics as well as a Master of Science. He remains dedicated to creating an environment where patients feel supported, informed, and confident throughout their orthodontic care.

Raised in the small town of Meers, Oklahoma, Dr. Cook developed a strong appreciation for community, connection, and trust, values that continue to shape his patient-first philosophy. He was drawn to orthodontics for its combination of scientific detail and creative problem-solving, as well as its ability to create meaningful changes in patients’ confidence, especially during adolescence. Since joining Harwell & Cook Orthodontics in 2014, he has worked closely with Dr. Harwell to deliver supportive, consistent care built on open communication and mutual trust.

Dr. Cook uses modern orthodontic technology, including digital treatment planning and self-ligating braces, to create efficient, comfortable, and highly individualized treatment experiences for patients of all ages. He earned his Bachelor of Science in Chemistry and Biochemistry and his Doctor of Dental Surgery degree from the University of Oklahoma, followed by a Master of Science and Certificate in Orthodontics.
