For Tonie Cherell Lewis, DDS, owner of Allen Smile Design, there’s no doubt in her mind that she is living her calling. She has known since childhood that she wanted to be a dentist. When a car accident left her with a broken jaw at age eight, she needed multiple surgeries and visits to the dentist’s office during her recovery. This experience created a curiosity for dentistry and a love for helping others.

As a young student, Dr. Lewis nurtured her passion for science and learning, going on to graduate as the valedictorian of her high school class. She credits her father for instilling the value of hard work and compassion for other people. “My dad has always been a hard worker,” she says. “He encouraged me to not only do my very best, but also to treat others how I would like to be treated.”

After high school, Dr. Lewis continued on a path of academic excellence, earning a Bachelor of Science in biological sciences and a minor in chemistry with honors from the University of Southern Mississippi. She then attended Howard University College of Dentistry, where she received the Community Dentistry Award and the Academy of Esthetic Dentistry Award.

When she reflects on her journey of excelling in school and opening her own state-of-the-art dental practice, Allen Smile Design, Dr. Lewis attributes her success to a lifelong love of learning. “I always had the desire to learn more,” she says. “Whatever the achievement, I knew there was something more to be gained. The dental field is always changing. There is always a new technology to learn about. I love that part of it.”

Dr. Lewis, who is a member of the American Academy of Cosmetic Dentistry and certified in laser dentistry and Invisalign, is committed to continuing education so she can provide the highest quality care for her patients.

Allen Smile Design provides a full range of dental services, including preventive dentistry, cosmetic dentistry, periodontal therapy, root canal therapy, dental implant restorations, and TMJ/TMD therapy. The practice is equipped with the most advanced technology, including all-digital X-rays and scanners, to provide the most comfortable patient experience.

The most rewarding part of her job? Helping her patients feel comfortable and completely at ease in her care. “I love getting to know my patients and creating relationships with them,” says Dr. Lewis. “It’s what I find most fulfilling in what I get to do every day.”

In practice for more than 15 years, Dr. Lewis is grateful she listened to her father and her mentors and took the courageous step into entrepreneurship. “When starting my practice, I had to overcome a fear of failure,” she says. “I’m glad I had faith to step out and pursue my dreams.”
