Hi, I’m Kathryn.

or Katie.


A brief history….


When I’m not writing or working as a Chief of Staff, I love learning, training in Krav Maga, being outside and exploring the world.


 

Meet Montbriand Services

 

 

During my 15-year career as a consultant and Fortune 500 leader, I became an exceptional generalist. My search for new challenges led me through credit underwriting, marketing, product, operations, and Chief of Staff roles. Each position offered a chance to grow and add tools to my leadership kit.

I learned to jump into any problem, function, or organizational dynamic, make sense of the current state quickly, and create a plan. I developed strategies to build trust and design a team culture that fosters collaboration and results. In short, I became a force multiplier.

Along the way, I also discovered a gift for capturing the voice and vision of the leaders I worked with. Whether it was crafting board updates, keynote speeches, or thought leadership articles, I could translate complex ideas into clear, compelling narratives that inspired action. That ability became the foundation for my ghostwriting work — helping leaders sound like their best selves without having to find the time or the words on their own.

In 2021, I took a sabbatical. During this break, I re-evaluated my skills and clarified the focus for my next career chapter. The answer was resoundingly clear:
Do the things I am best at. Play the multiplier role as a Chief of Staff for companies reaching the next level of growth — and give their ideas a powerful voice through ghostwriting.

This clarity led me to form Montbriand Services, LLC, a company that offers Chief of Staff and ghostwriting services to business leaders who want their time back to focus on what they do best.

 

Experience + expertise = results


Why Work With Us?

"Katie Montbriand was the Chief of Staff for a divisional leader at Capital One, accountable for more than 1000 employees. Katie’s maturity as a COS is the best I’ve seen in my career. She anchored a team of senior leaders to a higher sense of purpose, mainly to elevate the lives of our customers and associates, while also aligning us toward tangible short-term results.

Katie effortlessly balances assertiveness with kindness, competitiveness with compassion, and fearlessness with humility. During her time as COS, we produced powerful results and had a lot of fun doing it. I highly recommend Katie for jobs as President of a start-up, a C-level leader of an established company, and of course as a COS of a Fortune 100."
