Meet Our Doctor
David Chang
Founder of Well Balanced Self-Healing Medicine
President of Well Family Acupuncture & Herbs and Well Family Integrative Medicine Clinic
Proud father of a son and daughter
Dr. David Chang began his medical journey at National Yang Ming University in Taipei. After graduation, he served in the Navy hospital in Penghu and later worked in the Nuclear Medicine Department in Taichung. During these years, he gradually recognized the limitations of modern medicine and was inspired to pursue Traditional Chinese Medicine (TCM) at South Baylo University in Los Angeles. Alongside his studies, he apprenticed under Dr. Ni, a renowned master of classical TCM in Florida, and completed his Doctorate in Acupuncture and Oriental Medicine in 2009.
In 2010, Dr. Chang was introduced to Yuan Shi Dian (YSD), a groundbreaking medical discovery developed by Master Chang Chao Han in Taiwan. After applying YSD in his practice and treating thousands of patients, he came to see both the strengths and blind spots of TCM. Realizing the profound importance of this new medical perspective for humanity and future generations, he began nonprofit volunteer work in 2011 to share YSD with the public.
In 2012, Dr. Chang opened his private acupuncture practice in Chino to serve the community. His mission is not only to treat illness with the highest quality of care, but also to empower patients with simple, effective methods to stay healthy and live without fear of disease.
William Lin
William Lin has dedicated his career to improving people’s health, well-being, and future opportunities. He graduated in 2010 with a master degree in Traditional Chinese Medicine, specializing in acupuncture and herbal medicine. Early in his journey, he worked as a health instructor at a local association, teaching community members how to live healthier, more balanced lives.
William’s professional path has been diverse. He served as a General Manager of a major food chain company for three years, later becoming an entrepreneur to help individuals and families strengthen their financial futures. He also worked as a college consultant for five years, guiding high school students in identifying their dream schools, applying successfully, and preparing for fulfilling careers.
In 2022, William returned to his original passion for healing. After intensive training with his mentor, Dr. David Chang, he earned his acupuncture license in April 2023. Today, he serves the community through his two acupuncture clinics located in Chino, California, and El Monte, California. In addition to his private practice, he also provides care for patients in sub-acute units and medical facilities, supporting individuals with a wide range of critical health conditions.
Through every stage of his journey, William’s mission has remained the same: supporting people on their path to health, balance, and a brighter future.
