This year L.E.K. Consulting turns 30. It’s a wonderful age—old enough to feel confident, yet still youthful. We are full of fresh ideas, new thinking, and enthusiasm for helping our clients meet the challenges of the next 30 years—and beyond. As the 30th anniversary of our founding draws to a close, we look back on our history and some of the more memorable innovations that have made us the successful global consultancy that we are today.
