Your Board-Certified Orthodontist

Get To Know Dr. Tina Siu

Dr. Tina Siu grew up in Alhambra, California, close to the current office location in San Marino. Her mother, Dr. Annie Siu, was an orthodontist, and her father was an anesthesiologist. Both of Dr. Siu's parents were very involved in the local community in Alhambra. She considered doing medicine when she first entered college at Occidental College in Eagle Rock, Los Angeles, but after careful consideration, she decided to purse dentistry instead. After exploring the different specialties in dentistry, she decided that Orthodontics was the right one for her because it allowed her to work with children and adults and create beautiful, confident smiles. 

After completing her undergraduate degree at Occidental College, Dr. Siu attended dental school at the USC School of Dentistry, where she was later accepted into the USC graduate orthodontic department, earning her orthodontic certificate and a Master’s degree in Craniofacial Biology. Dr. Siu is also a diplomate of the American Board of Orthodontics, making her Board-Certified.

When she’s not in the office, Dr. Siu enjoys golfing, learning to cook new dishes, and playing with her Australian Labradoodle, Rufus.

Your Board-Eligible Orthodontist

Get To Know Dr. Daniel Chee

Dr. Daniel Chee was born and raised just a few blocks away from our orthodontic office, right here in San Marino. He knew he wanted to go into a healthcare profession of some kind, since so many of his family members are physicians, dentists, and nurses. Although he had not yet decided completely, he already had his eyes on orthodontics, since he witnessed first-hand the impact his mother’s work had upon his community–it was a common experience to be stopped at the store or on a walk by one of her happy patients. 

Dr. Chee attended the University of Southern California, where he earned a Bachelors of Science in Human Biology with a focus on Applied Physiology, as well as a Business minor. His interest in dentistry grew, and he chose to stay at USC for another 4 years for dental school. While he was in dental school, Dr. Chee realized that the aspect of dentistry he loved the most was treatment planning, so he decided to follow in his mothers footsteps (and his grandmother's footsteps!) to become an orthodontist. Dr. Chee chose to stay at USC for an additional 3 years (11 years in total at USC!) to complete his orthodontic training, and he loved every second of it. 

In his free time, Dr. Chee loves spending time with his wife Erin and his dog Bumi, playing beach volleyball, and playing League of Legends, where he gets to engage his strategic and problem-solving skills.

Community Outreach

Our philosophy of care goes beyond the office walls. We believe that it’s our responsibility to care for our patients, both in and out of the operating chair, and one of the best ways to do this is through our community outreach programs.

We partner with Young and Healthy Pasadena to provide free oral health screenings to children in Kindergarten and Elementary school. Through Young and Healthy, we also provide comprehensive orthodontic treatment to children in need. We are proud supporters of the San Marino Schools Foundation, and Dr. Siu served as a trustee on the Schools Foundation for twelve years.
