In October 2023, Katie faced a new challenge when diagnosed with the genetic cancer mutation CDH1, leading to a battle with gastric stomach cancer and a full stomach removal. Undeterred, she launched a research fund for gastric stomach cancer under the banner of KT STRONG, with Dr. Vivian Strong leading the charge. Guided by her unwavering zest for life, family, friends, real estate, research, and philanthropy, Katie's dreams find fulfillment.

Katie's journey is truly inspiring, from her idyllic upbringing in Grand Beach to her unwavering commitment to her family, career, and philanthropy despite facing a daunting health challenge. Her resilience and determination shine through, not only in her personal battle but also in her efforts to raise awareness and support for gastric stomach cancer research through KT STRONG. She's a testament to the power of love, strength, and community in overcoming adversity.

Supported by her husband and three remarkable children – Sean, Patty, and Kathryn – all graduates of prestigious universities, the Haggerty family stands united in championing Katie's KT STRONG mission. And amidst their bustling household, the love of their two golden retrievers, Coors and Guinness, adds warmth and joy to their lives.
