Episode Notes

At John Mattone Global, we stand by a guiding principle: “Prescription before diagnosis is malpractice.” But what does that really mean in the context of leadership coaching—and how do we accurately diagnose a leader’s strengths and blind spots?

Joining us today is Dr. Nina Steigerwald, an Industrial-Organizational Psychologist whose work is redefining how leaders grow—by combining data-driven insights with meaningful coaching. Dr. Steigerwald will walk us through how I/O Psychology informs every step of the coaching journey—from assessment design to deep personal transformation. She’ll shed light on common misconceptions about workplace surveys, the rising embrace of data-informed development, and how Intelligent Leadership translates psychological science into practical strategy.

Whether you’re leading a team, guiding executives, or simply curious about how evidence can amplify empathy—this conversation highlights why assessments are more than metrics: they’re catalysts for change when guided by the right coaching philosophy.

Dr. Nina Steigerwald joins Rich and Maikel for a deep dive into the science of leadership development and the indispensable role assessments play on this episode of Mainline Executive Coaching ACT.
