Yuri
Director of Operations
Since joining Orthodontic Consultants in 2010, I've had the privilege of working in a field I’m passionate about, transforming smiles and making a positive impact on both children and adults. Witnessing the confidence that comes with a beautiful smile is incredibly rewarding. Outside of work, I absolutely love cheering my kids on at soccer games and gymnastics meets, and supporting their growth and interests. In my downtime, I enjoy diving into our office Book Club selections and pursuing my personal fitness goals.
