Choose a Board-Certified Orthodontist

Not Every Orthodontist Is Board Certified!

Less than 50% of all orthodontists in the United States are Board Certified, and Dr. Yang is one of only three Board Certified Orthodontists within 10 miles of Redwood City.

ABO Board Certification is a voluntary credential that represents an orthodontist’s personal and public commitment to the standards of specialty practice and lifelong learning. The ABO Certification process requires the completion of peer-developed, externally validated written and clinical examinations. A Board Certified Orthodontist has reached this level of achievement by pursuing additional voluntary education and ongoing self- assessment. 

Board Certification is confirmation of an orthodontist’s personal commitment to providing lifelong quality patient care.

The initial process of becoming board certified can take anywhere from five to ten years. Once certified, the orthodontist must become recertified every ten years to maintain board-certified status.


Founded in 1929 as the first specialty board in dentistry, The American Board of Orthodontics (ABO) is the only orthodontic specialty board recognized by the American Dental Association and in affiliation with the American Association of Orthodontists.The Board upholds four main objectives supported by its mission:

The ABO’s aim is to elevate the standards of the practice of orthodontia, to familiarize the public with its aim and ideals, and to protect the public against irresponsible and unqualified practitioners.


The Board upholds four main objectives supported by its mission:


  1.  To evaluate the knowledge and clinical skills of graduates of accredited orthodontic programs by conducting exams and conferring time-limited certificates
  2.  To re-evaluate clinical knowledge and skills through administration of recertification exams throughout a Diplomate’s career
  3.  To support the development of quality graduate, postgraduate, and continuing education programs in orthodontics
  4.  To promote and encourage certification expertise throughout the world
