Kathi in real life

Why do you like working at Mercer Advisors?

The Mercer Advisors one-team culture fosters a collaborative environment that empowers me to deliver exceptional service to our clients. We have a deep bench of experienced specialists who share their expertise and insights; this collective knowledge enhances our ability to address the distinct and evolving needs of our clients with care.

Favorite thing about where you live?

I live in Missoula, Montana, and enjoy spending time at my family’s ranch in the scenic Mission Valley. I’m an avid outdoor enthusiast, finding joy in hiking, mountain biking, and exploring the woods and mountains. Family is at the heart of my life. My husband and I have four children and a grandson, and I cherish every moment spent with them.

What makes you tick?

I’m energized by the pursuit of meaningful goals — personally and professionally. Whether raising four children, launching a small business, racing bikes, coaching athletes, or building a career in wealth management, I’ve always embraced challenges with determination and curiosity. I often say, “I want to have it all,” which for me means being open to new experiences and striving for growth in every area of life. Today, I channel that same drive into helping clients achieve Economic Freedom™ and live the lives they envision.
