About Brian Greene

I lead complex, high-stakes project and implementation programs for Strategic Accounts within Fortune 100 and 500 organizations—where ambiguity is real, timelines matter, and failure is not an option.With 27 years in wireless telecom, I specialize in taking large, messy, post-sale commitments and turning them into executed outcomes. I’ve spent my career operating at the intersection of enterprise customers, internal delivery teams, and executive expectations—owning everything from greenfield deployments to merger-driven integrations, large-scale onboarding programs, and long-tail operational support.My strength is not just managing projects—it’s orchestrating execution across engineering, operations, sales, legal, care, and leadership when the path forward isn’t clearly defined. I’m comfortable stepping into uncharted territory, building structure where none exists, and driving momentum without waiting for perfect conditions.I’ve led strategic implementations spanning telecom, IoT, fixed wireless, and 5G-enabled solutions, delivering measurable business outcomes including a $22M reduction in operational costs through redesigned onboarding and delivery models. I partner closely with enterprise customers to align technical delivery with business reality—ensuring what’s sold can actually be deployed, supported, and scaled.Colleagues and customers know me as the person brought in when the work is complex, the visibility is high, and the tolerance for missteps is low. I thrive in environments that demand accountability, adaptability, and clear communication across diverse stakeholder groups.If you’re looking for a strategic account implementation leader who can take ownership from contract through clean execution—and keep both customers and internal teams aligned along the way—I’m always open to the conversation.
