SPOTLIGHT
Yoon Hang Kim MD
www.directintegrativecare.com is a membership-based, insurance-free telemedicine practice led by Yoon Hang Kim, MD, MPH — board-certified in Preventive Medicine and practicing Integrative & Functional Medicine. The model is deliberately small: membership is capped at 99 active clients so that each person receives the time, continuity, and depth of thinking that a conventional volume-driven clinic cannot provide. Rather than billing third-party payers, the practice runs on transparent monthly membership tiers with a one-time registration fee, which removes coding pressure and lets clinical decisions follow the client's actual needs rather than reimbursement rules. The clinical work centers on root-cause medicine for complex, often poorly served conditions — low-dose naltrexone therapy, autoimmune disease, chronic pain, fibromyalgia and chronic fatigue, mast cell activation syndrome, mold-related illness, and integrative oncology support. Dr. Kim brings more than twenty years of practice, an Osher/Weil fellowship at the University of Arizona, UCLA medical acupuncture certification, and IFM Scholar designation, along with three books and a peer-reviewed publication record. That background shapes an approach that pairs conventional preventive medicine rigor — testing strategy, risk framing, number-needed-to-treat thinking — with integrative modalities, so clients get evidence-anchored guidance rather than either extreme. Care is delivered primarily by telemedicine across a defined set of licensed states (Texas, Iowa, Illinois, Missouri, Georgia, and Florida), with an in-person presence at Hill Country Integrative Medicine in Fredericksburg, Texas, and planned expansion toward San Antonio. For clients outside those jurisdictions, including international ones, the practice offers educational consultations under a signed agreement framework rather than a treating relationship. Alongside direct clinical care, Dr. Kim maintains a substantial educational footprint — a long-running LDN support community of 9,000+ members, an extensive clinical blog, and continuing-education work for clinicians — which functions both as a public resource and as the practice's primary front door.
