How we’re different

We focus on growth strategy

Unlike large consulting firms who toggle between operational work and heterogenous strategy work, we live and breathe healthcare growth strategy. As a result, we have developed deep expertise in exploring new business models, evaluating new technologies, entering new markets, and capitalizing on new policies. Our focus drives results.

We prioritize pragmatism and clarity

We pride ourselves on developing elegant solutions to complex problems. We share a passion for helping our clients devise winning strategies and gain organization buy-in through clear business cases, impactful storytelling, and actionable recommendations.

We believe in data-driven decision making

Insight generation and quantitative rigor define our consulting approach. We are experts at designing research to inform quantitative models, developing forecasts in emerging and innovative markets, and quantifying what is difficult to quantify.

We deliver a first-class client experience

We value collaboration and partnership above all else and design our engagements to follow a highly iterative process. We start fast, deliver against compressed timelines and respond to changing client needs with agility. Our senior leaders remain actively involved throughout our engagements and set a high standard of excellence.
