His death was attributed to unforeseen complications following a complex surgical procedure, marking a tragic end to a life that was rich with purpose, faith, and service to others.
Born on December 8, 1961, in Stillwater, Oklahoma, Gillett grew up in Rolla, Missouri, where he developed traits of hard work and independence through various childhood endeavors, including raising chickens. He displayed remarkable academic and athletic prowess, excelling in multiple sports such as football, basketball, baseball, track, and golf. Summers were filled with adventures riding ponies and motorcycles, working odd jobs, and participating in activities at Little Prairie Bible Camp, which helped lay the foundation for his disciplined and adventurous spirit.
Gillett attended Harding University, where he made lasting memories by pledging TNT and performing as a tenor in the Harding A Cappella Chorus. His travels took him across Europe with the Chorus, enriching his experiences, and he devoted time to sharing the gospel with Campus Crusade for Christ while pursuing a Bachelor of Business Administration in Accounting. He passed the CPA exam on his very first attempt, marking the start of his successful career in finance.
Gillett began his professional journey in public accounting, later achieving a Master of Business Administration from Harvard Business School. His extensive career spanned nearly four decades, during which he was involved in transactions totaling over $20 billion. He co-founded Speyside Partners and Blackhill Partners and held executive positions at several notable firms, including Credit Suisse First Boston and Price Waterhouse. Known for his exceptional clarity in complex situations and talent for building consensus, colleagues described him as possessing keen business acumen and a heartfelt spirit of kindness, frequently bringing joy to the workplace with his infectious laughter.
His commitment to family was paramount, as Gillett displayed immense love and devotion to his wife, Leigh, and their four children: Katharine, John, Joseph, and Elizabeth, along with his two grandchildren, Miles and Margaret Clarke. He often took the lead in planning family vacations and celebrations, meticulously preparing detailed itineraries to create memorable experiences. Gillett also prioritized serving others, often helping those in need without seeking recognition.
Outside of work and family, Gillett enjoyed a variety of hobbies including singing, cooking, reading, and spending time in nature. He was an avid sports fan, particularly passionate about football and horse racing. As a man of faith, he found strength in God, especially during challenging times, and was known for living a life that reflected purpose, generosity, and joy.
Gillett is survived by his devoted family: his wife Leigh, children Katharine, John, Joseph, Elizabeth, grandchildren Miles and Margaret, and his parents Bill and Clara Gillett. He also leaves behind his two sisters, Kristie and Laura, several in-laws, nieces, nephews, and many friends who cherished him. His two beloved Australian Shepherds, Ansel and Theo, also survive him.
