Guaranteed Smiles

The Foundation of Designer Smiles of Colorado

At Guaranteed Smiles, we built a reputation for excellence in general and cosmetic dentistry, helping our patients achieve the healthy, radiant smiles they deserve. Founded by Dr. Margarita Aleksanyan, DDS, FAACD, our practice began as a place where quality care met personalized attention. Over the years, as our passion for transformative cosmetic dentistry grew, so did our vision.



With advancements in technology, artistry, and an unwavering commitment to perfecting smiles, Guaranteed Smiles evolved into Designer Smiles of Colorado—a premier destination for world-class cosmetic dentistry.

A Legacy of Excellence

Dr. Margarita Aleksanyan, FAACD is the only dentist in Colorado to achieve Fellowship Status with the American Academy of Cosmetic Dentistry (AACD)—an honor held by fewer than 100 dentists worldwide. Her expertise in smile design, porcelain veneers, and advanced aesthetic treatments set the foundation for what is now Designer Smiles of Colorado.



Her commitment remains the same: to provide the highest level of care, whether you're enhancing your smile with a cosmetic procedure or maintaining your long-term oral health.
