Sun initially pursued a doctorate in pharmacy and practiced as a pharmacist for 10 years. After undergoing several knee surgeries for sports-related injuries, he began exploring acupuncture and Traditional Chinese Medicine (TCM) as an alternative approach to Western medicine, which heavily relied on surgery and pharmaceuticals for pain management and recovery. Through TCM, Sun found a more comprehensive and holistic approach to well-being and healing, which motivated him to shift his focus away from pharmacy and pursue TCM. He graduated from the Oregon College of Oriental Medicine and later traveled to rural Nepal with the Acupuncture Relief Project, providing medical care to underserved communities. Sun has since established his private practice in Kailua-Kona, Hawaii, where he provides holistic healthcare services to those seeking a more natural approach to their well-being.

Acupuncture is frequently sought out by patients experiencing musculoskeletal injury, and Sun's approach offers a comprehensive approach to healing and recovery by integrating both Eastern and Western medical perspectives. Sun's technique incorporates various acupuncture methods such as motor entry point acupuncture, myofascial trigger point acupuncture/dry-needling, neuroanatomical and myofascial channel theory, and zang-fu organ differentiation, all of which takes into account the anatomical and physiological changes associated with disease or injury from both biomedical and TCM perspectives. In addition to acupuncture, Sun's treatment regimen involves a range of supplementary healing modalities such as electro-acupuncture (also known as percutaneous electrical nerve stimulation), cupping (a negative pressure myofascial decompression technique), electro-cupping (which combines cupping with transcutaneous electrical nerve stimulation), guasha (instrument-assisted soft tissue mobilization), red/near infrared light therapy, PEMF (pulsed electromagnetic field) therapy, and herbal medicine. The combination of these various methods can effectively address the underlying causes of the patient's condition.

Sun is nationally board-certified in acupuncture and herbal medicine (Diplomate of Oriental Medicine (NCCAOM)®. He has received specialized training in acupuncture for sports and orthopedic injuries, acute and chronic pain management, sports performance enhancement, and the evaluation and treatment of trigger points and myofascial pain syndromes. This extensive training has earned him certifications as a Certified Sports Medicine Acupuncture Specialist® and Certified Myofascial Trigger Point Therapist - Dry Needling Acupuncture®. Sun is committed to consistently improving his skills and knowledge in the field of pain science by pursuing additional training specifically focused on musculoskeletal and orthopedic conditions.
