Shannon Dunham represents companies in business and transactional matters, including mergers and acquisitions, and the negotiation of enterprise-level agreements, including technology, software and content licensing and development.

Backed by over 20 years of broadband and telecommunications industry experience, including nine years as in-house counsel at a publicly traded Fortune 100 operator, Shannon has provided legal support for all aspects of technical operations. She leverages that experience to serve her many broadband, telecommunications and media clients today.

By integrating into the client’s operations, she is able to respond swiftly, identify opportunities and address operational issues effectively. Always striving for efficiency and risk minimization, she takes a proactive approach, anticipating concerns and proposing solutions before problems arise.

She has functioned as outside corporate counsel, advising broadband companies on their general operations and a host of business matters. She has developed compliance programs, privacy policies, conducted internal audits and has led, managed and coordinated interdisciplinary teams on numerous special projects.

Her experience further extends to advising clients across various industries on procurement and consumer protection issues including advertising and promotions, and issues regarding sweepstakes and contests.
