About Us

Our Story

For more than 30 years, Dr. Bob has had the privilege of caring for families throughout Renton, Issaquah, Bellevue, Newcastle, Kent, Seattle, and surrounding areas. Generations of patients have grown up in his chair, and for him, orthodontics has always been about more than straightening teeth — it has been about relationships, trust, and delivering the highest quality of care.

Throughout his career, Dr. Bob remained deeply committed not only to his local community but also to serving others around the world. Even after retirement, his passion continues as he participates in mission trips to South America, providing orthodontic care to underserved communities. His heart for service has always guided the culture of the practice.

When the time came for Dr. Bob to retire, he thoughtfully chose Dr. Bill Wan to continue that legacy of excellence. Dr. Bill was honored to be entrusted with the care of Dr. Bob's patients and their families. Sharing the same commitment to patient-centered care, Dr. Bill also brought fresh energy and advanced technology to the practice — enhancing workflow and equipment, improving software, and elevating the overall patient experience while preserving the warmth and personal touch patients have always known.

The transition occurred during the challenges of COVID, a time of uncertainty for many. Yet both doctors worked closely together to ensure continuity of care. Side by side, they guided the team and supported patients every step of the way. Their collaboration created a seamless, stable transition that prioritized safety, communication, and consistency.

Today, that strong foundation continues. With a passionate and experienced team, the practice blends decades of trusted tradition with modern innovation. Our commitment remains the same: exceptional orthodontic care, genuine relationships, and dedicated service to the Renton, Issaquah, Bellevue, and Newcastle communities for many years to come.

We are grateful for the trust you place in us — and we look forward to continuing to serve your family with the same heart and excellence that have defined this practice from the very beginning.
