"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."
