who we are

Financial improvements on both ends of the income statement come when curiosity and logic are supported with data. Our firm name is derived from the word ‘empirical’, which emphasizes Empierus’ fact-driven approach to achieving sustainable client results.

With decades of healthcare operational and supply chain experiences and an entrepreneurial passion for helping our clients navigate beyond the status quo, we look forward to teaming up on your next project.
