Invisible Leadership: How Support Roles Shape Company Culture

By Mallory Mason, CP, PACE

When we think about who shapes company culture, we typically look to the C-suite, department heads, or designated culture champions. Yet some of the most influential cultural architects operate largely behind the scenes: Executive Assistants and Chiefs of Staff.

The Cultural Gravity of Support Roles

As an EA for over a decade and now advising organizations on executive effectiveness, I’ve witnessed firsthand how these “invisible leaders” create ripple effects that transform entire organizations. Here’s how:

1. They Set the Tone for Communication

EAs and Chiefs of Staff often control the flow and tone of communication to and from leadership. They:

• Determine which messages reach executives and how they’re framed
• Model communication styles that others emulate
• Create templates and systems that standardize organizational dialogue
• Buffer interactions during tense situations, preserving relationships

When an EA responds thoughtfully to a frustrated stakeholder rather than dismissively, they’re not just handling a task—they’re demonstrating the organization’s values in action.

2. They Establish Accessibility Norms

Who gets time with leadership profoundly impacts company hierarchy and inclusion:

• Choices about meeting prioritization signal what (and who) truly matters
• Calendar management decisions reflect and reinforce power structures
• Accessibility protocols determine if leadership operates in a bubble or stays connected
• Informal interactions facilitated (or blocked) shape relationship networks

A Chief of Staff who ensures frontline employees occasionally get face time with the CEO creates a fundamentally different culture than one who builds impenetrable walls around leadership.

3. They Embody Values Before They’re Official

Support professionals often implement values-based decisions before they’re formalized:

• Instituting sustainability practices in executive offices
• Championing work-life boundaries even when not explicitly required
• Creating inclusive meeting environments through thoughtful planning
• Handling confidential information with integrity, setting the standard

I once worked with an EA who quietly ensured her executive’s travel included carbon offsets long before the company announced its sustainability initiative. That invisible leadership helped catalyze a broader cultural shift.

4. They Manage the Leadership Temperature

Support roles regulate the emotional climate of leadership, which cascades throughout the organization:

• Providing context that helps executives respond proportionately to challenges
• Creating space for reflection before reactive decisions
• Protecting leadership’s energy for high-value interactions
• Filtering and prioritizing information to prevent overwhelm

The difference between a leader who appears consistently composed versus constantly frantic often comes down to the effectiveness of their support team.

The Multiplier Effect

What makes these cultural contributions so powerful is their multiplication across countless interactions. A single decision by an EA or Chief of Staff about how to handle a situation creates a template that others follow.

For example, when a Chief of Staff demonstrates that challenging the status quo is welcomed rather than punished, that permission ripples through the organization, unlocking innovation at all levels.

Elevating Invisible Leadership

For organizations seeking to leverage this powerful cultural force:

1. Recognize the influence: Acknowledge support roles as culture carriers, not just task managers
2. Include them in culture conversations: Bring EAs and Chiefs of Staff into discussions about organizational values and culture initiatives
3. Invest in their development: Provide training on organizational dynamics and cultural intelligence
4. Create feedback loops: Establish mechanisms for support professionals to share cultural insights they uniquely observe
5. Celebrate their impact: Make visible the typically invisible contributions these roles make

The Cultural Legacy

The most effective EAs and Chiefs of Staff understand that their influence extends far beyond managing calendars or coordinating logistics. They recognize that each interaction is an opportunity to reinforce or reshape culture.

As one CEO recently told me: “My previous EA shaped how this company operates in ways I’m still discovering years later. She built bridges across departments I didn’t even know needed connecting.”
