Understand the facts, identify decision-makers, clarify risks, and build a strategy

Shifts in telecom, cloud, and data infrastructure put legal teams under pressure to keep pace with the business while handling disputes across jurisdictions, systems, and stakeholders. At Lumen Technologies, this dynamic plays out daily in litigation, discovery, and operational decisions. Vann Ellerbruch, Senior Attorney, operates at this intersection, where legal analysis informs business decisions. He helps teams act with clarity as cases progress and data moves through the enterprise.
“ I’ ve always gravitated toward roles where complex systems, problem-solving, and public impact come together,” Vann says. At Lumen, a global technology and telecommunications company that connects people, data, and applications through network, security, and cloud services, this focus has shaped his approach to in-house practice.“ The opportunity to serve as both a legal advisor and a strategic partner within a large-scale organization truly appealed to me,” he continues.
Path to in-house
Vann started his career in environmental work and public service, formed by environmental restoration projects.“ During college, I spent time on environmental restoration initiatives, which showed me how regulation, science, land use, and day-to-day operations all come together,” he says. During a response to a diesel spill in rural Wisconsin, fuel leaked into a stream, and helping to contain it and restore the river was meaningful.“ Seeing how much people cared about the river and its wildlife moved me deeply,” Vann says. Law school built on that foundation. He focused on environmental and natural resources law and joined a clinic representing a Native American tribe in a dispute with a pipeline developer.“ That experience highlighted how environmental law can affect people’ s lives in real ways,” he says. It also influenced how he approaches legal work more broadly.“ You’ re not just reading statutes and cases; you’ re weighing science, economics, public policy, operational realities, and long-term outcomes,” he adds.
After graduation, he joined the Colorado Attorney General’ s Office as a legal fellow, handling cases and investigations with a public dimension.“ I learned how to analyze disputes, manage investigations, and work through matters that needed a public focus,” he says. The experience reinforced discipline around facts and process.“ It taught me the value of careful investigation, clear judgment, and responsible stewardship of information,” he says.
He moved in-house soon after.“ I decided to go in-house because I wanted to be part of the business, to spot issues early, and to help shape outcomes before disputes escalated. That closeness to decision-making was appealing then, and it still is,” Vann explains.
Litigation as an enabler
At Lumen, Vann handles a variety of litigation, including corporate, consumer, and environmental, along with property disputes. He also heads the eDiscovery practice for Lumen. The job requires turning risk into guidance that teams can act on.“ In-house practice has changed. Litigation support isn’ t just about reacting to claims or minimizing exposure after the fact. It’ s about helping the business act with confidence, earlier in the process,” he says.
Understand the facts, identify decision-makers, clarify risks, and build a strategy
That shift shapes how he structures his work.“ It means translating legal risk into practical guidance, finding clear paths through discovery and resolution, and recommending approaches that make things easier for internal teams,” Vann notes. His approach relies on fundamentals.“ Every matter is different, but the core disciplines remain: understand the facts, identify decision-makers, clarify risks, and build a strategy that’ s sound on the law and workable in practice,” he adds.
