Tachlion was founded by Dr. Stephen Epstein to help healthcare and mission-driven organizations solve the problems that matter.
Three decades as an emergency physician and 25 years teaching at Harvard Medical School taught him to make decisions under pressure, see patterns in complexity, and always keep the human stakes in focus.
His background—engineering from Yale, medicine and public policy from Harvard—creates an uncommon perspective: analytical precision meets human-centered values meets systems thinking. The result? Strategic counsel that’s rigorous and practical, thoughtful and effective, principled and pragmatic.
Dr. Epstein also serves as an external advisor at McKinsey & Company.
