My Xtreme Hike Story
Fundraising for Gateway Xtreme Hike 2026
Mary Jane Tierney
We're so back! Year 14! Team Isabelle is so proud to have raised so much money as a team, and now we are supporting team David!
This past year I am THRILLED to report I crossed that line after hiking 30.1 Miles!
I could not have done it without my dad, John Tierney, and the rest of the Huron Team! They have joined in on the Xtreme Hike and have shown such selflessness in their efforts for this organization.
Personally, this Hike has changed my life in endless ways. Physically, mentally, and emotionally I have grown into myself, and the volunteers and other hikers are whom to thank.
I've volunteered at several Xtreme Hikes and Cystic Fibrosis events, and I'm thrilled to be hiking for the third year! My passion for community service has flourished through organizations like Special Olympics and Habitat for Humanity, and I even traveled to Costa Rica to help transform a school into an intentional learning community. At Mizzou, I was part of the Chi Omega Fraternity, Rho-Alpha chapter, where I served on the philanthropy committee and as Director of Philanthropy, working with Make-A-Wish to grant wishes for Wish Kids. Organizing fundraisers and connecting with our Wish family are cherished college memories.
After graduating from the University of Missouri-Columbia, I am a proud Keeley'n at Keeley Construction Group in St. Louis, MO where I serve as a Commercial Interior Designer. I'm grateful for Keeley's commitment to values, particularly philanthropy, through KeeleyCares, which encourages employees to engage in community involvement by volunteering our time, talent, and treasure. I also serve as a KeeleyLife Champion, as apart of Keeley's core value of sustaining a culture of health and well-being for all Keeley'ns and their families.
Let's take Team Isabelle to the end of the year!
UNTIL IT ENDS!
