Dr. Maggie’s Path to Dentistry

Dr. Maggie's journey into dentistry began in the heart of Armenia, where she was born and raised. As a child, she spent countless afternoons in her mother’s dental clinic, captivated by the transformative work happening there. Watching her mother and colleagues care for patients with a mix of precision, compassion and artistry left an indelible impression on young Maggie. She eagerly observed as her mother alleviated pain, restored smiles and made meaningful connections with every patient. 


Looking back, Dr. Maggie sees those early experiences as the foundation of her passion for dentistry. The joy of relieving pain, restoring confidence, and crafting perfect smiles continues to inspire her every day. She firmly believes that a smile is far more than a physical feature—it’s a personal statement and a source of empowerment. “Your smile is your calling card,” she says. “It’s one of the first things people notice about you, and it shapes their perception moving forward. A great smile can transform your life.” This philosophy is embodied in her personal motto: Improve Your Smile. Improve Your Life.


Today, Dr. Maggie leads Designer Smiles of Colorado, where she and her team offer an unparalleled blend of general and FAACD-quality cosmetic dentistry. But what truly sets them apart is their warm, patient-centered approach, which makes visiting the dentist feel more like catching up with family.


Dr. Maggie’s dedication goes beyond technical excellence. She has inherited her mother’s compassion, warmth, and unwavering belief that every patient deserves the very best care. For Dr. Maggie, dentistry isn’t just about teeth—it’s about empowering people to live their best lives, one brilliant smile at a time.
