What We Believe
We believe that life is about the people we meet and the happiness we share. We are passionate about people and so we accumulate relationships (not things!). We laugh often and smile more. Research even shows that smiling can make you happy. And happiness is contagious, in a good way. Life is beautiful. Live your dream. Do what you love. For us, that just happens to be orthodontics.

Your Kids
The American Association of Orthodontists recommends your little ones be screened around age 7 for developmental problems in the jaws and permanent teeth. Some problems are simply easier to correct and better for your child when treated early. Early intervention orthodontic options at our Claremont, Sierra Madre, and South Pasadena orthodontist locations include expanders, growth modification, and braces.
Your Teens
Early adolescence is the perfect time to start comprehensive orthodontic treatment. At Wu Orthodontics, we believe in helping our patients build self-confidence. Our braces treatments include clear braces and metal braces. Our Invisalign Teen® treatment helps them achieve a confident smile without all the metal!
Yourself
Our adults deserve an amazing smile too! Whether your teeth shifted after childhood braces or you’re ready for a full smile makeover, our team is here to help. Wu Orthodontics offers traditional braces, as well as adult Invisalign® treatment and clear braces for a more discreet appearance. Other Wu Orthodontics adult patients are treated with active aligners and retainers.

Meet Dr. Guiselle Murillo
Your Orthodontist in Claremont, Sierra Madre, and South Pasadena
Dr. Guiselle Murillo is a passionate orthodontist who entered the field in order to share the great experience and outcome she received from her own orthodontic treatment.
Dr. Murillo completed her orthodontic residency and obtained her Doctor of Dental Surgery, Master of Science in Oral Biology, and Bachelor of Science in Biology degrees at the University of California Los Angeles. She is a member of the American Association of Orthodontists, Pacific Coast Society of Orthodontists, American Dental Association, and California Dental Association.
The summer she got her braces off, she shadowed her orthodontist and knew she had found the perfect career path. Dr. Guiselle’s favorite parts about her job are the relationships with patients and the privilege to build their confidence in a positive and uplifting environment. In her free time, Dr. Guiselle enjoys Pilates, exploring new restaurants and cafés, and baking. She especially loves quality time with her niece and family. You may also find her cheering on the Dodgers during baseball season!
"I decided to become an orthodontist after experiencing the transformative effect that orthodontic treatment had on me at 13 years old. Growing up, I was teased because of my smile, but orthodontic treatment gave me newfound confidence!
