ABOUT

Two Decades Inside the World's Top Executive Offices. Now Working Fractionally.

I'm Vanessa Gotthainer, founder of C-Level Executive Advisors — a fractional Chief of Staff and operations practice serving consulting firms, founder-led teams, and mission-driven organizations.

For more than two decades, I worked inside some of the most demanding executive environments in the world — supporting Chairmen, CEOs, COOs, and CIOs across global finance, management consulting, and international education. My work has always centered on the same thing: bringing structure, clarity, and disciplined execution to environments where priorities shift quickly and the stakes are high.

Those environments included:

Merrill Lynch · Citigroup · Rothschild & Co · BlackRock · Morgan Stanley · McKinsey Global Institute · NYU Shanghai

In each of these roles, I wasn't a bystander to how senior leadership operated. I was inside it — managing the prioritization, the coordination, the systems, and the follow-through that kept complex organizations moving at the highest levels.

C-Level Executive Advisors was built from that experience — to give consulting firms and founder-led organizations access to that same level of operational leadership on a fractional basis, without the overhead of a full-time hire.

How it all started...

I didn't set out to start a business. I set out to solve a problem I had seen repeatedly throughout my career.

Throughout my career, I worked closely with executives and founders navigating fast-moving priorities, high-stakes decisions, and constant demands on their time. What they consistently needed wasn't more people or more tools. They needed one person who could step in, think ahead, and own the operational layer behind the scenes — someone with the judgment and experience to handle complexity without being managed through it.

I founded C-Level Executive Advisors in 2018 to meet that need.

Today I work as a fractional Chief of Staff and Operations Lead for a small number of clients at a time. I work embedded in their organizations — not as a project resource, but as a consistent operational partner who shows up week over week, owns execution across priorities, and builds the systems that reduce friction over time.

Most of my engagements run one to three years. That longevity isn't accidental. It reflects what happens when the right operational infrastructure is in place — leadership teams move faster, priorities follow through, and the organization stops losing momentum to coordination gaps.

What Clients Privately Appreciate—and Publicly Endorse

I had the pleasure of working with Vanessa at two different firms, The Hennessy Group and NGT BioPharma Consultants. Vanessa was always very efficient and well organized, eager to take on projects and always got things done. She used initiative to identify needs and always had suggestions for addressing them. Both firms are virtual firms with people spread around and outside the US, and Vanessa was very effective at keeping everyone connected and informed and made sure that things didn't slip through the cracks. - Ed H.

Vanessa has excellent Administrative skills. She is intuitive and a very responsible individual who works at a very high-level of accuracy and production. Vanessa is able to handle multiple tasks at a senior level both efficiently and timely. She takes pride in her work product. She is a loyal and dedicated employee.

Vanessa is very capable of performing at high levels as an individual contributor. - Catherine M.

I've had the opportunity to work with Vanessa through multiple roles and organizations in my consulting work and have been impressed time and again with the versatility and depth that she brings to every job and task she undertakes. Vanessa's approach is always measured and nuanced yet creative and thoughtful, whether she's coaching and supporting members of the C-Team, managing projects, or something in between. Vanessa deeply connects with both the people and markets she works with and would be an amazing addition to any organization. - Jeanie C.

Ready for Someone to Own Execution So You Don't Have To?

I work with a small number of clients at a time to ensure each organization gets the depth of operational partnership it needs. Engagements are limited.

If you're a founder, managing partner, or executive director carrying operational weight that should belong to a dedicated role — I'd welcome a conversation.
