Continuing a Tradition of High-Quality Dental Care

about us

About Us

The high-quality care we provide at D.C. Smile Studio continues the tradition started thirty years ago when Dr. Samuel Lievano opened his first dental practice. His deeply loyal patients have entrusted their dental care to the practice through all these years.


Dr. Lievano and Dr. Viviana Avila-Gnau share the same passion for dentistry and the same desire to provide the best care for our patients, and we are confident that you will feel right at home in our office. We welcome all patients as if they were family, and we invite you to join us!


We work hard to keep up with the latest advances in technology. We have outfitted our state-of-the-art facility with the latest equipment, allowing us to meet your needs and provide you with the most modern, high quality dental care available.

Welcome to your dental practice!

We are here to help you, whether you are looking to maintain your healthy teeth or to improve your dental health, whether you are seeking to keep the smile you have or to get the smile you’ve always wanted. With our compassionate, caring approach, we are here to help you reach your goals. Even the most fearful patients have given themselves the opportunity to be treated here, and they are happy they did when they realize they can trust us and overcome their fear.


We can provide a wide array of dental services that you and your family may need, including routine checkups and cleanings, repair of tooth damage, Invisalign®, cosmetic dentistry, TMJ pain, and treatment of more complex dental-related issues. We may even be able to help you with problems such as snoring and sleep apnea.
