Se-Young Kim, L.Ac
Dr. Se-Young Kim’s journey to becoming an acupuncturist began with a lifelong love of sports and movement. Growing up, he played soccer, basketball, and golf, and earned a 3rd-degree black belt in Taekwondo. Witnessing sports injuries among his peers sparked his curiosity about how the human body works and set him on a path of study and training that included specialized experience with the Republic of Korea Marine Corps and later business school in the United States, where he pursued his family’s legacy.
During this time, Dr. Kim discovered his true passion for helping people heal both physically and mentally. He began teaching Pilates and eventually owned and operated his own Pilates studio in Los Angeles for 11 years. Through this work, he found deep fulfillment in supporting others on their wellness journeys. His desire to expand his knowledge and clinical skills led him to study Traditional Korean Medicine at Dongguk University, Los Angeles.
Today, Dr. Kim focuses on treating sports injuries, post-surgical recovery, and posture correction. His approach integrates acupuncture, Tuina manual therapy, and therapeutic stretching, all while emphasizing clear communication and patient-centered care.
Dr. Kim’s goal is not only to facilitate healing but also to make a meaningful impact on each patient’s overall well-being. His combined experience as both a Pilates master and acupuncturist gives him a unique perspective on movement, rehabilitation, and holistic care. He is dedicated to helping patients achieve long-lasting improvements in health, function, and quality of life.

Hansung Jang, L.Ac.
Dr. Hansung Jang combines Eastern medicine with modern clinical insight to help people relieve pain and move more comfortably. His approach is precise and patient-centered, applying only the treatments that are needed, exactly where they make the most difference. He also guides practical changes in daily habits such as diet, breathing, and movement to support long-term balance and overall health.
Dr. Jang studied Health Promotion and Disease Prevention at USC, where he gained a deep understanding of how lifestyle and stress affect the body. He later completed a master’s degree in Acupuncture and Oriental Medicine at South Baylo University, building a strong clinical foundation in anatomy, physiology, and pathology. This background allows him to look beyond symptoms, understand the deeper patterns behind them, and design treatments with lasting results in mind.
Each treatment is carefully tailored to the patient’s condition and may include acupuncture, electroacupuncture, cupping, gua sha, or herbal medicine. Dr. Jang also works with breath rhythm, retraining movement in the neck and upper back, small micro-movements, and functional rehab coaching. These tools are designed to create meaningful improvements that extend beyond the treatment room into daily life.
Dr. Jang frequently treats neck and back pain, shoulder and knee issues, muscle tension from desk work, tension headaches, digestive discomfort, and stress-related fatigue. His goal is not only to relieve pain but also to restore how the body moves and functions day to day.
Clear communication is central to his practice. Dr. Jang works closely with patients to map out their goals and identify sustainable changes, believing that small adjustments today can lead to meaningful progress tomorrow and a lighter, more manageable routine.
