Considering braces? Treatment starts with a careful evaluation of your bite. We design a personalized plan, fit the right type of braces for your case, and guide you through every adjustment to a fully aligned smile. Consistent care and follow-through are what deliver lasting results
Considering clear aligners? The right plan starts with a thorough evaluation. We assess your case, design a custom aligner sequence, and guide you through treatment to deliver predictable results. Consistent wear and proper planning are what turn aligners into a lasting smile
Wondering when your child should first see an orthodontist? Early evaluation is key. We assess jaw growth, tooth eruption, and habits that can affect alignment, then monitor development and step in only when needed. Catching issues early keeps future treatment shorter, simpler, and less invasive
Worried about your child's developing bite or crowded teeth? Early evaluation is key. We assess jaw growth and tooth eruption, then use targeted appliances like expanders, space maintainers, or growth modification therapy to guide development before problems become harder to fix. Acting at the right age makes future treatment shorter and simpler
Dealing with crowded teeth, a misaligned bite, or a jaw discrepancy? Accurate diagnosis comes first. We evaluate the case in full, design a targeted treatment plan, and guide you through the right combination of braces, aligners, or surgical orthodontics to correct the problem. Consistent care and proper retention are what make the result last
Just finished braces or clear aligners? Retention is what protects your results. We fit you with the right type of retainer and monitor your alignment over time to prevent relapse. Consistent retention is the difference between a temporary fix and a lasting smile
Since 1995, we have helped more than 20,000 patients across Honolulu, Kahala, and Mililani achieve confident, lasting smiles. Our patient-first approach means every visit feels personal, comfortable, and built around you.

Patient Care
"We take the time to answer every question, so you feel confident and excited about your smile journey."
We believe every patient deserves a healthy, confident smile regardless of their financial situation. That is why we work with most major insurance plans and take the time to verify your coverage and help you get the most out of your benefits before treatment begins.
For patients with out-of-pocket costs or no insurance, we offer flexible payment options including CareCredit financing and in-house plans with transparent pricing. Our team is happy to walk you through every option so you can focus on your smile, not the paperwork.
Our Oahu locations are designed to feel welcoming from the moment you walk in. Modern, comfortable, and built with your experience in mind.
