Our Promise
Employee benefits are personal. That’s why we believe the people behind your benefits administrator matter just as much as the technology they use.

We’re proud that our clients don’t just know our company—they know our people.
Rachel Humbird
Chief Executive Officer
Rachel’s journey at Peak One Administration is a reflection of the company’s values and culture. She began her career with Peak One as the receptionist and, over the past two decades, has held a variety of roles across the organization before becoming Chief Executive Officer.
That experience has given Rachel a unique perspective on every aspect of the business—from serving participants and supporting clients to leading operations and shaping the company’s long-term vision. Having worked alongside nearly every department, she understands firsthand what it takes to deliver an exceptional client experience.
Today, Rachel leads Peak One with a focus on building lasting relationships, supporting her team, and continually improving the way employers, brokers, and employees experience benefits administration. She believes the best solutions come from listening first, communicating openly, and never losing sight of the people behind every benefits plan.
Under Rachel’s leadership, Peak One continues to grow while remaining true to the values that have guided the company since its founding: personalized service, trusted expertise, and a commitment to making benefits administration simpler for every client.
Outside the office, Rachel enjoys spending time with her husband, Scott, and their two cats, Sheldon and Leonard. Whether she’s skiing in the winter, wake surfing in the summer, golfing, or exploring the beautiful Northwest, she enjoys making the most of every season.
