The First 90 Days: How Leaders Build Trust & Earned Authority.

Summary

The first ninety days of an executive transition are critical.

For healthcare leaders stepping into a new organization, this early window is not just about learning the role or setting strategy. It is about building trust, understanding culture, earning credibility, and establishing the foundation for long-term success.

In this episode of Perspectives with Pinnacle, John Carter sits down with Neil Marshall and Kurt Mosley of HealthSearch Partners to discuss what separates leaders who build early momentum from those who struggle to gain traction. Drawing from thousands of executive interviews, healthcare leadership transitions, and recruiting engagements, the conversation focuses on what successful leaders do before they act, how they earn authority beyond their title, and why culture can either accelerate or derail a transition.

Throughout the conversation, the group also explored how small symbolic leadership actions often communicate more than formal strategy, helping executives shape culture and build credibility early in their tenure.

What emerged was a clear theme: the first ninety days are less about proving you have all the answers and more about earning trust, understanding culture, and establishing the credibility required to lead effectively.

Key Takeaways

• Trust matters more than strategy early on.
  Leaders who enter a new organization and immediately try to execute strategy often struggle. The most successful executives focus first on building relationships, listening, understanding the organization, and setting the tone for how they will lead.
• Authority is earned, not assigned.
  A title may provide positional authority, but it does not automatically create trust or supporters. Leaders earn credibility through consistency, visibility, listening, and action.
• Listening has to be intentional and structured.
  Passive listening is not enough. The conversation emphasized the importance of creating systems for listening, whether through leadership rounding, one-on-one conversations, or direct engagement with employees across the organization.
• Small symbolic actions can shape culture quickly.
  Actions often communicate more than speeches, emails, or formal announcements. Whether it is addressing a visible operational issue, walking the parking lot to pick up trash, eating in the cafeteria, or fixing something frontline staff have identified, symbolic acts can build trust when they are authentic and aligned with the leader’s values.
• Moving too fast can create lasting damage.
  Executives are often under pressure to make changes quickly, but the discussion emphasized the importance of being “quick, but not hurried.” Leaders need to assess quickly, listen quickly, and understand the culture before making major decisions.
• Misreading culture can derail a transition.
  Even the right leader in the right organization can struggle if they misread the culture early. Culture acts as a multiplier, strengthening effective leadership actions or magnifying missteps.
• Organizations play a major role in executive success.
  Successful transitions do not depend on the executive alone. Boards and leadership teams need to be intentional about what the organization truly needs, align on priorities, and help create the conditions for the new leader to succeed.
• The first ninety days set the tone, but the work continues.
  A strong first ninety days creates momentum, but long-term impact requires consistency. Leaders must continue building trust, communicating visibly, and following through beyond the initial transition period.

Final Takeaways

The first ninety days are not about making the loudest entrance or proving immediate expertise. They are about building the trust required to lead.

Successful executives follow a disciplined sequence during transition: observe, listen, assess, then act.

Leaders who move too quickly into strategy before understanding the people, culture, and operational realities around them often create resistance instead of momentum.

What stood out most throughout the conversation was the idea of earned authority.

Leadership does not begin simply because someone has been given a title. It begins when people believe that leader understands the organization, respects its culture, and is willing to take action in ways that support the people doing the work every day.

The first ninety days may only be the beginning of a leader’s tenure, but they often determine the momentum, trust, and credibility that define everything that follows.
