Louis Geoffrey Greulich, “Geoff,” passed away on April 21, 2026 surrounded by family, leaving behind a legacy of integrity, intellectual curiosity, and deep devotion to those he loved.

Geoff was born in Summit, NJ and moved to Buenos Aires, Argentina as a newborn where he lived until he was 6 years old. After Argentina, he spent the remainder of his childhood years in Pittsburgh, Pennsylvania, where Geoff graduated from Shadyside Academy before attending Vanderbilt University, where he earned degrees in engineering and economics and was president of Phi Kappa Psi fraternity. He often described his decision to attend Vanderbilt as one of the most important of his life, setting the foundation for both his career and personal journey. He earned an MBA from the University of Chicago's Booth School of Business.

He began his career in 1983 with J&L Steel in Detroit, launching a path that would span decades across the manufacturing industry (GE Capital, Tenneco, Pactiv, American Business Products, Silgan, Levlad) and eventually private equity (Oaktree Capital, Corridor Capital). Throughout his professional life, Geoff was known not only for building successful businesses, but for his commitment to mentoring others and leading with respect and dedication.

Above all, Geoff was devoted to his family. He shared a remarkable partnership with his wife of 40 years, Beth, whom he described as his equal and complement in every way. Together, they built a life grounded in mutual respect and  adoration.  They raised three children - AJ, Shannon, and Charlie - whom he loved deeply and was immensely proud. Geoff found joy in life’s simple pleasures: fishing, golfing, hiking, or watching a sunset. He also lived for meaningful conversation with family and friends, ideally shared over a good bourbon. He approached life with optimism, curiosity, and a strongly rooted belief that balance is the key to life.

In retirement, following his ALS diagnosis, Geoff devoted himself to mentoring others and supporting Target ALS in its research mission. Determined to help spare others from the suffering caused by the disease, he worked to raise both awareness and funding. Even while facing the challenges of ALS, Geoff maintained a perspective that became emblematic of his resilience: “ALS sucks, but life is good.”

He is survived by his beloved wife, his three children, four grandchildren, and a wide circle of family, friends, and colleagues. He will be remembered for his generosity, love of good conversation, and lasting influence on those around him.
