Your Best Smile Awaits

SMILES BY DR. DADJOO

The Standard of a Dadjoo Smile — Meet Dr. Shaun Dadjoo

There is a difference between a smile that looks straight and a smile that is truly right. The difference lives in the details — the bite, the balance, the jaw, the soft tissue, the airway, and the way it all works together for a lifetime. That difference has a name. And it starts here.

We Don’t Try to See Everyone

At Dadjoo Orthodontics we see the patients we can truly serve — the ones who want a doctor who will personally call them back, personally design their treatment, and personally stand behind their result for life. That’s not something you can scale. It’s a choice we make every day.

Dr. Dadjoo personally oversees every case from your first consultation to the day your retainer goes in. No handoffs. No associates approving a plan he hasn’t reviewed. No software-generated prescription accepted without modification. Every treatment plan at this practice is designed by hand, by a doctor who trained at the highest level this profession offers, for the specific person sitting in the chair.

Our approach goes beyond moving teeth. We evaluate the full picture — hard tissue, soft tissue, jaw function, facial balance, airway, and smile design — because a truly exceptional result requires understanding everything, not just the crowding on your X-Ray.

That is the standard. And it has a name.

Dr. Shaun Dadjoo, DMD, MS, ABO-Board Certified Orthodontist

 Dr. Shaun Dadjoo, DMD, MS, ABO, was recruited to the Eastman Institute for Oral Health, — the #1 ranked orthodontic program in the world considered more prestigious that Harvard, UCLA, or USC. His training covered everything from simple tooth alignment to complex surgical cases, craniofacial growth, TMJ disorders, airway-focused orthodontics, and cleft lip and palate treatment. It is among the most comprehensive orthodontic educations available anywhere.

After completing his residency Dr. Dadjoo pursued and achieved board certification through the American Board of Orthodontics— a distinction held by fewer than one-third of orthodontists nationwide. As an ABO Diplomate he has demonstrated clinical mastery beyond what graduation alone requires.

He is also a published researcher. His work has appeared in leading peer-reviewed journals including CRANIO and the Journal of the California Dental Association. He authored the first published clinical trial on a novel technique to whiten teeth during Invisalign treatment. He has been nominated as Resident of the Year by the Journal of Clinical Orthodontics, earned first prize in the College of Diplomates of the ABO Case Competition, and received national recognition from the American Dental Education Association.

He is a member of the American Association of Orthodontists, the California Association of Orthodontists, the Pacific Coast Society of Orthodontists, and was selected by the CAO to serve on its Communications Committee — a peer-nominated appointment recognizing his professional standing and commitment to advancing the field.

And he is your neighbor. Our practice has been in Porter Ranch for over 16 years. He knows these streets, these schools, and these families. When he makes a treatment recommendation, it is the same recommendation he would make for his own daughter, his wife, or his parents. That is not a marketing statement. That is how he practices.

“I went to the best school in the world for orthodontics. I’ve published research. I’ve won the awards. But what I’m most proud of is that when a patient calls this office, I call them back. Every time.”

What 10,000 Hours of Specialist Training Actually Means

An orthodontic residency at a CODA-accredited program requires a minimum of two to three years of full-time, hospital-based clinical training. At the Eastman Institute that training encompasses the full spectrum of orthodontic complexity — from interceptive treatment in growing children to surgical orthodontics in adults, from simple crowding to complex interdisciplinary cases involving oral surgeons, periodontists, and prosthodontists.

The result is a doctor who has seen everything, treated everything, and knows the difference between a case that can be handled with a standard Invisalign prescription and case that requires something more. General dentists receive very little orthodontic training in dental school. Some complete a weekend Invisalign certification course. Dr. Dadjoo completed 10,000+ hours. That gap is real and it shows in the results.

16 Years. One Standard.

Dadjoo Orthodontics has been part of the Porter Ranch community since Dr. Jeffrey C. Liu opened these doors decades ago. When Dr. Liu entrusted his practice to Dr. Dadjoo, he wasn’t just passing along a patient list — he was passing along a relationship with a community. Families who came here as children are now bringing in their own children. That continuity is something we don’t take lightly.

Community Commitment

Dr. Dadjoo has reinvested more than $200,000 into the local community — sponsoring Porter Ranch Community School, Granada Hills Charter School, OYA Volleyball Club, and dozens of other local programs. He launched the Dadjoo Orthodontics Give Kids a Smile Scholarship, which awards three fully sponsored orthodontic treatments annually to deserving students nominated by their teachers. Dadjoo Orthodontics received a formal recommendation from the City of Los Angeles for 15 years of community service.

This practice is not a franchise. It is not a DSO. It is a doctor who lives here, treats here, and has chosen to build something lasting in the community he calls home.

Recognized and Trusted

Respected by colleagues in orthodontics and dentistry, Dr. Dadjoo is an emerging thought leader nationally, published author of A Parent’s Guide to Orthodontics, Growth, and Smiles That Last (available on Amazon and Kindle) and works closely with general dentists, pediatric specialists, and other providers to ensure coordinated, high-quality care. Many of our patients come through referrals from other doctors who trust our expertise and patient-centered approach, and many others find us online after searching for an orthodontic office that cares.

Built for Precision. Designed for You.

iTero Element 5D Scanner — Digital 3D impressions with no goopy molds, no discomfort, and a simulation of your expected treatment outcome before a single aligner is made.

Spectralase Diode Laser — In-office soft tissue procedures including tongue tie and lip tie releases, impacted tooth exposures, and gum contouring — all performed by Dr. Dadjoo without a separate specialist referral in qualifying cases.

3D Cephalometric Imaging — Full diagnostic records analyzed by Dr. Dadjoo personally — not a technician, not software alone — to understand your bone structure, jaw relationship, and growth pattern before treatment begins.

3D Printing — Our in-office 3D printer allows us to fabricate custom orthodontic appliances, surgical guides, and retainers with a level of precision and speed that traditional lab workflows simply cannot match. What once took weeks can now be designed, printed, and delivered in days — without sacrificing accuracy or fit.

Custom Treatment Planning — Dr. Dadjoo reviews and refines every Invisalign ClinCheck and every bracket prescription by hand. The software is the starting point. The expertise is what makes it exceptional.


Porter Ranch is Not Just Where We Practice. It’s Where We Live.

Dr. Dadjoo is an active sponsor of local schools and community events throughout Porter Ranch and Granada Hills. He has hosted Super Bowl MVP Malcolm Smith at the Granada Hills Charity Golf Tournament. He has been featured on YouTube channels with tens of millions of subscribers. He has been recognized by Parents.com and published in peer-reviewed journals rad by orthodontists around the world.

But what he is most proud of is simpler than any of that — the families who have trusted him with their children’s smiles. The patients who call the office and know someone will pick up or get back to them. The referring doctors who send their most complex cases here because they know the work will be done right.

That is the community we have built. And you are welcome in it.
