AboutKathleen C. Hwang Orthodontics

At Kathleen C. Hwang Orthodontics, we strive to help patients maintain a uniform smile that is in the proper alignment to benefit one’s oral health. Far too often, people assume they only need to brush twice a day in order to keep their teeth healthy. In reality, crooked teeth can trap food particles or plaque that will continue to damage the enamel over time. With our treatment, we can help to shift the teeth into the proper position and prevent the possibility of this from happening.

We can also treat patients of varying ages. By treating children, we can help build the foundation for healthy teeth early in their lives. If adults need orthodontic treatment, we have other options besides braces with Invisalign® and clear aligners. To find out which option will work best for you, contact us and schedule an appointment today.

Kathleen C. Hwang D.D.S.

It has always been my belief that outstanding patient care is a combination of quality work and an excellent patient experience. It is my constant goal to provide both of these to my patients, and deliver gentle and effective orthodontic care in a fun and friendly environment.

I love creating smiles and, as a result, helping each of my wonderful patients improve their self-esteem and self-confidence. Being an orthodontist is incredibly rewarding: not only am I able to help people have better lives, but every day I get to have amazing conversations with my patients. I look forward to hearing about what’s happening in their lives and sharing in their excitement when they have something big planned. I’m also humbled when they choose to confide in me, because they need someone to talk with and they trust me. Those one-on-one connections make me smile.

Outside of my practice, I am actively involved in my community and currently sit on the Board of the San Gabriel Valley Foundation for Dental Health, an organization committed to providing dental care to underserved people in the San Gabriel Valley area. I am also involved as a Board member of the Boys and Girls Club of the Foothills, an organization that provides a safe haven for kids to grow by providing quality programs that allow them to excel in school and lead healthy, productive lives.

Education and Commitment to Continuing Education

I attended UCLA for my Bachelor of Science in microbiology and molecular genetics, and then went to UCSF, where I was awarded my Doctorate of Dental Surgery. I returned to UCLA for my orthodontics residency. My formal education provided me with an excellent foundation, but I also know that being an oral healthcare provider means I must stay on the leading edge of developments in the field. Orthodontic technologies and treatment methodologies are constantly evolving, and I need to remain informed in order to provide my patients with the widest array of options to create the perfect individual smile for them.

  • Personal Life

    I was born in Taiwan. When I was three I moved to Sao Paulo, Brazil, where I grew up. My family moved to Arcadia in 1990 and I graduated from Arcadia High School. I love the area and returned here after spending time in San Francisco and Orange County.

    My two young children are the lights of our lives. Like all mothers, I juggle a schedule filled with extracurricular activities like sports, and cello lessons and concerts. To keep up with these two little ones, I make sure to prioritize my well-being, engaging in regular exercise to stay healthy, energized, and ready to balance family life and work.

    I enjoy traveling, experiencing different cultures, meeting people from different backgrounds, and exploring varied cuisines. I’ve traveled throughout Asia and Europe, and have gone to Guatemala to lecture to the Guatemalan Association of Orthodontists, and to China to lecture to the students and faculty at both National Taiwan University and Shanghai Ninth People’s Hospital.

    At my core, I am a people person, and being an orthodontist brings me into contact with some amazing individuals.

    Orthodontically yours,

    Dr. Kathleen Hwang and Team

    Dr. Lawrence Lin, a Board-eligible orthodontist, is a Southern California native. He grew up in Orange County, but considers LA his home. A true Bruin at heart, he earned his undergraduate degree from UCLA, graduating Summa Cum Laude with a degree in Economics. He then continued on to obtain his dental degree from the UCLA School of Dentistry, where he earned several honors and scholarships. He found the passion for orthodontics during this time in dental school and proceeded to obtain his Orthodontic specialty certificate from UCLA.

    During his time in college he started participating in CHAMPs, a mentorship program for the underprivileged youth, and continued with it while in dental school by becoming the health director for CHAMPs. His involvement at CHAMPs led him to create the Teen Oral Health Committee as a part of the American Student Dental Association to address the needs of oral health education among underprivileged youth, traveling to various middle schools in Los Angeles to teach oral hygiene.

    He is an active member of the American Dental Association, American Association of Orthodontists, and California Association of Orthodontists.

    Dr. Lawrence Lin enjoys orthodontics for its detail-oriented focus, the patient relationships, and the ability to give patients a smile they love. He also loves opportunities to serve, having traveled abroad to China to provide dental care for the underprivileged. He has spent a considerable amount of time learning Spanish and Mandarin to better connect with all his patients, and even attended National Taiwan University to enhance his language skills in Mandarin. He enjoys time with his family (he just got married!!!), reading, exercising and traveling.
