KEY MD Newport Beach is an elite concierge internal and pulmonary medicine practice founded by Dr. Kashif Yaqub, MD — a board-certified Pulmonary and Internal Medicine physician with over 23 years of clinical experience, trained at the University of Arizona and the Mayo Clinic. Built specifically for executives, entrepreneurs, and high-functioning professionals who demand healthcare that matches their level of sophistication, KEY MD combines expert internal medicine, advanced pulmonary expertise, and executive health strategy under a boutique, limited-panel membership model. Located at 4440 Von Karman Ave, Suite 350, Newport Beach, CA 92660, the practice is anchored by three pillars: continuity, physician judgment, and long-term health strategy — delivering the kind of proactive, deeply personalized care that conventional medicine is structurally incapable of providing.

About the Physician

Dr. Yaqub completed his training at the University of Arizona and the Mayo Clinic and serves as Voluntary Faculty at the University of California. After 23+ years in traditional medicine, he recognized that high-functioning patients needed a fundamentally different model — one centered on physician continuity, depth of evaluation, and long-term strategy rather than episodic, transactional care. He developed proprietary clinical frameworks including the Y4 Oxygen-First Method™, The Oxygen Audit™, and the Oxygen Report Card™ — tools that assess pulmonary function and oxygen delivery as foundational metrics for sustained energy, cognition, and resilience. KEY MD's membership panel is intentionally kept small to ensure every patient receives Dr. Yaqub's direct, sustained attention and the quality of engagement that is simply not possible in a high-volume practice.
