Minki Kim4514.jpg
Minki Kim, BA, LCMT
Structural Integration Therapist

Minki Kim thinks you are a unique individual. You are more than just a set of issues that need correcting. You’re a whole person with feelings, behaviors, thoughts, and goals with social roles within a larger community and society. He emphasizes client-centered care whereby the patient’s goals and meaningful activities provide a framework for personalized therapy. He treats you as a whole person and wants you to feel heard, seen, and listened to. You don’t neatly fit into a biomedical mold, rather I mold my
abilities towards you, your story, and your goals. "With a background in Rolfing Structural Integration, I employ a spectrum of touch to induce calm and ease rather than excite and stress the system. I promote self-dependence, confidence, and control back into people’s lives." He tries his best to rely on evidence and science-based research to effectively promote our natural ability to heal and move by using hands-on techniques, movement/exercise approaches, and education. He has a background in psychology and finds himself down plenty of rabbit holes in anatomy and physiology, science-based care, honing his humanistic/person-centered care, neuroscience, and pain research. In his off time, he’s with his 2 young kids, likes to cook, and settling in in his new home in NJ.
