Anderson O'Brien, LLP, a full-service law firm based in downtown Stevens Point, is celebrating 140 years of continuous legal service in central Wisconsin. The milestone, which dates back to 1886, places the firm among the oldest continuously operating law practices in the state, with few having maintained uninterrupted service to the same region for more than a century.
Founded by brothers Byron B. Park and Gilbert L. Park, the firm opened its doors at 933A Main Street in Stevens Point. Today, it operates from 1257 Main Street, not far from its original location. From the outset, the Parks established a collaborative model, eschewing the isolated practice common among attorneys of that era in favor of a team-based approach that pooled the expertise of multiple lawyers to serve clients.
Over its 140-year history, Anderson O'Brien has represented multiple generations of central Wisconsin families and businesses, building relationships that in some cases span decades. The firm has grown alongside the region, adapting to evolving legal needs while maintaining its roots in downtown Stevens Point. What began as a two-attorney office has developed into a team of 15 attorneys who concentrate in distinct areas of law, including personal injury, litigation, business and corporate law, estate planning, elder law, family law, employment law, real estate, tax planning, and workers' compensation.
The firm's longevity reflects its role as a community institution. Anderson O'Brien has received AV Preeminent peer-review recognition through Martindale-Hubbell, and individual attorneys have been recognized by Super Lawyers. Its attorneys actively participate in local organizations, nonprofits, and civic activities throughout central Wisconsin, serving clients in Portage, Adams, Waupaca, Waushara, and Wood counties.
The 140-year milestone is significant not only for the firm but for the legal profession in Wisconsin. It underscores the value of continuity and community engagement in legal practice, offering lessons for law firms nationwide about building enduring client relationships and adapting to change. For clients in central Wisconsin, the firm's deep local knowledge and long-term presence provide a stable foundation for addressing legal challenges.
As it enters its 141st year, Anderson O'Brien, LLP remains committed to the collaborative legal representation and community service that defined it at its founding. The firm continues to serve individuals, families, and businesses throughout Portage County and central Wisconsin, focusing on the next generation of clients while adapting to the evolving legal landscape.
