Get To Know Dr. Robert Lee

Dr. Robert Lee, a board-certified orthodontist and Southern California native, draws inspiration from his upbringing and family. His mother, a school psychologist, instilled in him a sense of care and empathy for others, while his father, an aerospace engineer, cultivated his critical thinking skills and innovative mindset. These formative experiences have shaped Dr. Lee’s treatment philosophy which focuses on treating patients like his own family with integrity, kindness, and excellence.

Knowing that he wanted to be an orthodontist from a young age, Dr. Lee earned his BS in bioengineering and DDS from UCLA. He then completed his Orthodontics Certificate and MS in Oral and Craniofacial Sciences at UCSF. He is now a part-time professor at the UCSF Orthodontics Program where he serves as the course director and lectures on clear aligner therapy (e.g., Invisalign).

Dr. Lee is the co-inventor and foremost authority of the InBrace system. He has treated and reviewed more InBrace cases than anyone in the world, and he wrote the textbook on the system. He also created the certification course used by all other InBrace providers in the world.

Dr. Lee is an expert in all aspects of digital orthodontics. He has helped develop many of the digital orthodontic solutions used worldwide. His remarkable contributions to the field of orthodontics are showcased through 25 publications, 7 cover-page articles, 4 granted patents, and 3 patents pending.

Dr. Lee is happily married to his wife, Stephanie, and they have two wonderful children. In his free time, Dr. Lee enjoys playing basketball and tennis. Dr. Lee looks forward to welcoming you and your family to the Life Orthodontics family!

Putting Patients First

Get To Know Dr. Sarah Pi

Dr. Sarah Pi is a board-certified orthodontist who grew up in Southern California. Dr. Pi studied psychobiology on the pre-health track at UCLA, but it wasn’t until she spent time working in a dental office after college that she discovered her passion for changing people’s lives through transforming their smiles. She then went on to complete her DDS, Orthodontics Certificate, and MS in Oral and Craniofacial Sciences at UCSF. Through her experiences being a scheduling coordinator, dental assistant, treatment coordinator, and office manager, she has gained an extensive understanding of the whole patient experience, which has contributed to her belief in treating patients with the utmost care and compassion to ensure that they are heard, understood, and comfortable throughout their orthodontic journeys.

Dr. Pi is a renowned expert in digital orthodontics and the InBrace system. She has over 15 publications, many on digital orthodontics which have been published in the top orthodontic journals. In addition, she is a clinical advisor for InBrace where she teaches and advises other orthodontists throughout the nation on how to use the InBrace system.

Smile for Life guarantee

After treatment, it is an all-too-common reality for patients to lose or break their retainers or experience minor relapse due to inconsistent retainer use. Typically you would have to pay a significant amount for a new retainer or retreatment, but at Life Orthodontics, we have you covered. Because we are committed to treating you like our own family members and we are proud of the smiles we create, we want to ensure the smile you love lasts a lifetime. That is why we provide our patients with an exclusive Smile for Life Guarantee which includes Retainer and Life Smile Insurance. Your smile is our priority, and as your Ortho Home, we are here to help you maintain it for life!

Retainer Insurance

If you lose or break your retainer, don’t worry! For a small copay, we will replace your retainer so you can keep your forever smile intact.

Life smile insurance

If your teeth ever shift on you, don’t worry! For a minimal copay, we will retreat you and have your forever smile restored.


Digital Orthodontics

At Life Orthodontics, we take pride in using state-of-the-art technology and a personalized approach tailored to your unique needs in order to craft your dream smile that lasts a lifetime.

3D Technology
In as little as a few minutes, we can capture a 3D model of your mouth using our modern intraoral scanner. This fully digital process means that goopy impressions are now a thing of the past!

With our cutting-edge CBCT (Cone Beam Computed Tomography) scanner, we can easily capture 3D x-rays of your jaws and teeth allowing us to more comprehensively evaluate and plan your bite and smile.

Digital Treatment Planning
Life Orthodontics is one of the few orthodontic practices that embraces a fully digital workflow, leading to faster treatment and fewer appointments. Prior to commencing treatment, we meticulously plan out every smile on the computer, enabling us to chart the most efficient path toward achieving your forever smile.
