After years of working in high-volume orthodontic practices, I
realized something was broken. Patients were being rushed through
appointments. Treatment plans felt cookie-cutter. And the artistry of
creating truly beautiful smiles was being sacrificed for revenue. When
the opportunity came to open my own practice in West Covina, I knew
this was my chance to do things differently. This community deserves
an orthodontist who takes time to listen, who sees every smile as a
unique masterpiece, and who refuses to compromise on results and
experiences.
One Smile Orthodontics isn't just a business - it's my
commitment to this community. Our patients will get my personal
attention, my years of training and expertise, and a smile
transformation that exceeds everything you hoped for.
Because you only get one smile. Let's make it extraordinary.

"If you are an adult patient who is considering a ortho treatment that you've been thinking about for your entire life, I highly recommend Dr. Kim. I was initially nervous about the process but Dr.Kim was very attentive and took time to come up with the plan that will address my concerns so I decided to start the treatment. My two main concerns were crowded lower anterior teeth and narrow upper jaw. Before starting the treatment, Dr. Kim clearly explained the treatment plan and timeline, which helped alleviate my concerns. Since I didn't want to wear the palate expander, Dr. Kim came up with alternative solution that can be done with Invisalign. Even as a first time ortho patient, I felt treatment plan was well thought out and precisely moving my teeth without causing excessive pain. I'm currently done with my initial treatment and waiting for refinements sets but I'm already very happy with the results so far. One Smile Orthodontics truly lives up to its name."

"I don't normally leave reviews, but after visiting Dr. Namgu Kim I feel compelled to share it. I went for a consultation about possibly getting braces or Invisalign, and as someone who always had a lot of anxiety around dental visits, I was honestly nervous walking in. But the moment I met Dr. Kim, I felt at ease. He has a reassuring presence and a genuine way of listening that makes you feel cared for as a patient — not rushed, not pressured, just understood. Dr. Kim took the time to thoroughly examine my teeth, explain what he was seeing, and walk me through my options in a way that was clear and easy to understand. He pointed out details that other dentists had overlooked and laid out a step-by-step plan that made me feel confident about what comes next. He focused on what would genuinely serve my needs and comfort level. As someone with dental anxiety, that meant a lot. For the first time, I felt like I was in the hands of a specialist who really prioritized my well-being. If you're considering orthodontic treatment — Invisalign, braces, or even just a professional opinion — I cannot recommend Dr. Namgu Kim highly enough."
