Our Mission

We’re passionate about people. That means giving you an unexpectedly awesome dental experience. An experience that is convenient for those who are crazy busy, focused on authentic relationships rather than just fixing teeth, and highly tailored to your needs and desires.

The Best Dentist in Tigard


Dr. Henderson wanted to become a dentist after participating in a humanitarian trip to the Dominican Republic. There he saw the positive impact dentists can have on someone. He was inspired by their ability to make connections, heal, and improve the health and overall quality of life of those they served.

He completed a bachelor’s degree in Korean and  attended dental school at Oregon Health & Science University. After graduating with his DMD degree, he has been serving patients in the Portland area ever since.

After practicing for several years, Dr. Henderson opened up The Smile Lounge so that he could focus on providing more attention and care to his patients. In particular, Dr. Henderson loves working with patients with autism and anxiety.

Dr. Henderson has a son who is autistic, and after talking with other parents of kids on the spectrum, realized that many other dentists in Tigard and the Portland area are too busy and lack the knowledge on how to provide dental care to those with autism. Learn more about what we do to accommodate our autistic patients here.

We Love Tigard


At The Smile Lounge, we are passionate about making our community smile. For us, that means going beyond dentistry. With every new patient that comes into our practice, we donate sensory tools to children in the community who are challenged with autism.

Dr. Henderson knows the challenges that these children face as he has a son who is on the autism spectrum. He has seen firsthand how valuable and transformative these sensory tools are. 

To help carry out this mission, The Smile Lounge has partnered with a local non-profit, The Shadow Project. They work with local schools and provide support for students with disabilities. The Shadow Project creates sensory spaces in local schools and sends out sensory kits to kids in our community. They also work with students with challenges like ADHD and dyslexia to improve their reading ability and develop the skill of goal setting.

When you book an appointment with us, not only will you have a top-notch dental experience, you’ll also know that you’re helping to make a positive impact in our community. Do good for your smile and Tigard by scheduling your next visit today!
