Our mission

One Health Consulting Group provides best-in-class consulting and resources that guide and fuel your business, organization or practice through the complex environment of consumer-driven and value-based healthcare. Our model is built on a platform of patient satisfaction, provider wellness,  growth of practices and markets, system integration, scalability and long-term sustainability.


Our care model

In addition to our healthcare background, we differentiate ourselves with an approach based on three pillars.

Centered around patients

Healthcare delivery should change lives and improve the health of individuals, businesses, systems and communities through a consumer-centric lens.

Driven by physicians

Physicians play a crucial role in the success of healthcare. Whether developing leaders or decreasing burnout, we’re committed to improving the well-being of all providers.

Partnered in care

To create excellence in healthcare, collaboration is essential. We provide expertise, leadership and resources to build partnerships under a value-based umbrella.


Our holistic approach

Everything must work together for you to provide the best outcomes, cost and value. Our holistic approach combines care for one individual, one system and one community. By addressing each element, you achieve a transformation that lasts.

One System. One individual. One community. One Health.

One individual

We’re focused on improved health and wellness for all individuals – patients and providers. Our approach delivers a low-cost way for patients to get highly personal, high-quality care. In addition, we believe provider wellness is essential in delivering excellent patient care, which is why we focus on four key areas:

  • Allowing autonomy
  • Increasing wellness
  • Providing stable compensation
  • Building a compassionate and inspiring culture

One system

When healthcare works as one system, consumers navigate it more easily and corporations experience more success. By bringing together key partners, we create integrated care models that lower healthcare costs and improve likability of health plans. Together we’re focused on a shared goal: providing value to our patients and communities.

One community

At One Health Consulting Group, we empower communities to be healthy by helping make care accessible and affordable for everyone. We believe an individual’s background shouldn’t determine the quality of care received, nor should they have to choose between food, housing and healthcare. Our approach to delivery transformation actively seeks to include the excluded, enriching the experience for all.
