Transforming Healthcare
Through Smarter Management.
At Sigora Healthcare, we believe operational excellence is the foundation of exceptional patient care. Our centralized management model empowers healthcare providers to focus on healing while we handle the business of healthcare — driving performance, compliance, and growth across every facility we serve.
Our Story
From a single management office in 2015 to a nationwide network, Sigora Healthcare was founded on one principle — that healthcare organizations thrive when business operations are as strong as their clinical care. Through strategic acquisitions, data-driven systems, and a people-first philosophy, we’ve built a model that combines local autonomy with corporate strength.
Today, Sigora supports dozens of hospitals, clinics, labs, and dental practices under one mission: to simplify operations, strengthen outcomes, and ensure long-term financial stability for our partners.

At Sigora, Sarah’s vision is simple yet transformative — to build a management infrastructure that allows providers to focus on care, not complexity. Her leadership emphasizes innovation, fiscal responsibility, and a culture of service that drives measurable results across all Sigora-affiliated facilities.
