Orthodontic Assistant

Originally from the Philippines, Nikaya made Washington her home six years ago.  Although she had taken some nursing classes, her true calling led her to the dental field, where she embarked on her journey as an orthodontic assistant four years ago.

Nikaya fills her free time with playing computer games, exploring new areas, and embracing new experiences. Nikaya brings warmth, skill, and a genuine love for her work to our orthodontic practice.

The best part about being an orthodontic assistant is seeing our patients with bright eyes and a wide smile after their treatment. I also really enjoy learning new things everyday from patients and my co-workers.


Orthodontic Assistant

Emilio brings both skill and compassion to our team. Born in Los Angeles, California and raised in Baltimore, Maryland, Emilio has been dedicated to the orthodontic field since 2018. He discovered his passion for orthodontics after undergoing life-changing orthodontic treatment himself. In his free time, Emilio loves to travel, stay active through exercise, and spend time with family and friends.

My love and passion for orthodontics push me to be a better assistant for each of my patients. As a detail-oriented person, every small detail counts to achieve that million-dollar smile.


Financial Coordinator

Siobhan began her career in orthodontics as an Orthodontic Assistant in 2008. As our dedicated Financial Coordinator, she not only brings extensive knowledge and exceptional expertise in the realm of Orthodontics but also takes immense joy in assisting individuals in attaining their desired smiles. When she’s not at work, she loves spending time with her son and exploring the great outdoors.

Helping people improve their oral health and achieve their desired smiles is such a rewarding experience.
