When you think of your workplace culture, what descriptions come to mind? Do those descriptors support business growth? What words describe how the culture helps facilitate great work from employees? If your culture inhibits both organizational and employee growth, then a culture of mediocracy settles in.

The tricky reality with culture is it's difficult to articulate a common definition of the current reality. Initiate conversations about what needs to change and you'll hear myriad variations. What's more, culture change takes time, money, and many founders and executives lose patience with the pace of it. Yet, we know from decades of research that culture is central to many desirable business outcomes: growth, profit, and innovation, for starters.

Certainly, there is no shortage of experts with an opinion and methods to shape and change workplace culture. (Full disclosure: I'm one of those experts with an opinion and methods.)

If there are so many leaders in the space, why aren't more workplace cultures extraordinary?

• As long as humans are involved in doing the work, culture change will be messy
• Change triggers our fear response and not all of us respond positively
• Culture is context and context is extremely nuanced
• The influencers of culture, social trends, technology advancements, and global and local economy and political trends, are always evolving

While the realities of changing a culture come with an arsenal of challenges, there is hope. There have been significant advancements in academic research, highly visible CEOs successfully showing new ways to partner with employees, and practitioners and consultants sharing their solutions and insights about more effective culture change solutions.

What follows is a list of men and women shaping how cultures change today. Some are experts in purpose, positive psychology, values-based leadership, grit, workplace intelligence, employee experience, and that's just some of the ways to evolve your workplace culture.

The list is comprehensive but imperfect. Because of the quality and quantity of people helping improve organizational life, I can't go into detail on every person. Those featured below are some of my personal favorites and also have unique, specialized input into the discipline of changing workplace culture. My goal, though, is not perfection. Rather, it is to point you in the direction of people who might help you deepen your understanding of how to change your company or team's culture.

Let's get to work.
