How we work

Clinical-performance medicine. Direct access. No noise.

1:1 Physician Care

You work directly with Dr. Rezvankhoo. Every decision, interpretation, and protocol comes from a physician triple board-certified in Emergency Medicine, Critical Care, and Neurocritical Care.

Deep Clinical Evaluation

Your first engagement is a 60–90 minute history and physiologic review. No rushed visits. No waiting rooms. No generic intake. Your physiology is mapped with the same rigor used in acute-care environments.

Advanced Biomarker Architecture

Comprehensive cardiac, metabolic, endocrine, inflammatory, and neurologic labs. Interpreted by a clinician trained to manage these systems at their point of failure.

Goal-Driven Protocols

Care is structured around what you are trying to accomplish — performance, longevity, metabolic optimization, or risk reduction. Clear endpoints. Measurable outcomes. No indefinite monthly fees.

Direct Access & Ongoing Oversight

You have direct communication with your physician and the Koléni Team. Protocols are adjusted as your physiology changes. Your care is not delegated, outsourced, or automated.

Performance-Grade Insight

VO₂ max, lactate kinetics, cardiac output, recovery physiology — the same metrics used in endurance sport applied to long-term health. Performance and longevity are the same physiology at different intensities.

A Deliberately Small Practice

Koléni maintains a limited roster to preserve the one thing modern healthcare cannot deliver at scale: sustained clinical attention from a physician trained to catch problems early and treat them well.
