Forged in complexity. Applied with precision.

Régine Villain spent three decades inside the operating core of healthcare, leading transformation at the intersection of clinical demand, enterprise complexity, and the hard constraints of supply chain and operations. She has sat on every side of a large institution’s decision-making: the clinical, the financial, the operational, and the strategic. That experience shaped a particular kind of attention. She learned to read the distance between what organizations plan and what they are actually built to do, and she learned to work in that distance.

REHVÉAL™ is where that work now lives. The practice advises founders, investors, and enterprise leadership teams building organizations that must perform through complexity, not around it. Clients come to REHVÉAL™ when the strategy is sound but the organization is not yet ready to receive it, when the operating model needs to catch up with the ambition, when the partnerships and ecosystem relationships need to be designed rather than hoped for, and when the decisions that will determine the next five years are being made now.

The practice is deeply rooted in healthcare but extends across industries where bold ideas have to navigate real-world complexity to achieve adoption and scale. Régine engages across U.S. and European ecosystems, bringing a cross-market perspective to transformation, innovation, and strategic access.

She is Founder and Principal of REHVÉAL™.
