Every leader is wearing one of these jerseys. Most don't know which one.

“Working with Tamika, I know her to be an extraordinary leader in business and the not-for-profit world. She has demonstrated the ability to configure and mobilize diverse, multidisciplinary teams to make the impossible happen.”

“Tamika’s writing style is tantamount to corporate parables—the points are effectively packaged in relatable stories. Only someone who has been there and done that could have written this book. Tamika’s 5x3 is tantamount to legendary 49ers coach Bill Walsh’s West Coast Offense. Fundamentals are foundational; however, differentiation is evolutionary. Leaders only get the best from their teams when position proficiencies reconcile with both the business life cycle and target market landscape.”

“After leading global organizations, serving on public company boards, building my own firm, and competing on successful sports teams, I’ve learned one consistent truth: Winning teams are rarely the ones with the most talent. Winning teams are the ones where everyone knows their role, plays it fully, and trusts their teammates to do the same. Win or Win gives leaders a practical system to build trust, accountability, and high performance.”

“As a founder, multi-time CEO, and investor, I’ve watched misaligned leadership teams silently destroy businesses that had every reason to succeed. Win or Win gives leaders what most frameworks don’t: a common language, an objective lens, and the self-awareness to know what their business needs at every stage. Tamika has written the book I wish every leadership team I’ve ever worked with had read first.”
