Gregory F. Ahrens

Wood Herron & Evans has lost a beloved partner, colleague, mentor, and friend. Greg Ahrens was—and will always remain—a stalwart of our firm.

Over the past weeks, we have mourned his passing while also celebrating the privilege of having known him. As a firm, we recently gathered to share memories and reflect on the extraordinary impact Greg had on all of us. We offer a few of those reflections here.

Greg was, quite simply, someone who drew people in. Many of us recall being instantly charmed by him—his warmth, his presence, and his genuine interest in others. He had a rare ability to make people feel welcome, valued, and reassured. In moments of uncertainty, Greg was the calm in the storm—his steady voice, thoughtful guidance, and unshakable confidence reminding clients and colleagues alike that “we’ve got this.”

A nationally recognized patent litigator, Greg devoted more than 40 years to fiercely advocating for his clients. He practiced in a high-stakes arena where fortunes, innovations, and futures hung in the balance—and he met that responsibility with brilliance, integrity, and grace. He was respected not only by those who stood beside him, but also by those across the courtroom. Though Greg earned the distinction of Super Lawyer and Best Lawyer, those titles only begin to capture who he was. To us—and to so many others—he was a truly exceptional lawyer in every sense: steadfast, principled, and deeply human.

Within the firm, Greg was a partner in every sense of the word. A leader and a confidant, he gave selflessly of his time and energy to many facets of the firm. Colleagues leaned on him and trusted him implicitly. He took pride in mentoring others; he didn’t simply meet people—he built relationships. Colleagues became friends, clients became family, and strangers became welcome guests.

Greg’s enthusiasm for life was unmistakable. Whether recalling his legendary rugby days, answering the call to help those in need, or sharing a laugh in the hallway, he lived fully and generously. His faith was evident not in words, but in the way he treated people—with kindness, patience, and humility. His love for his family was quiet, steady, and profound—a constant foundation throughout his life.

Greg’s presence—both personal and professional—will be deeply missed. We are better for having known him, for having worked alongside him, and for having called him our friend.
