Dennis Reilly is a former Fortune 100 marketing executive and longtime agency leader who now advises CEOs and executive teams navigating moments of transformation. He joins the UNH Paul College faculty as a Lecturer of Marketing, where he leads a section of the Marketing Capstone Workshop — bringing three decades of hands-on brand-building experience directly into the classroom to prepare students for the realities of the job market.

Over his career, Dennis has led large-scale rebranding initiatives, restructured marketing organizations, and aligned product, marketing, and sales functions to drive measurable growth. He spent nearly two decades at Digitas, one of the world's leading marketing agencies, where he led client relationships including Ally Bank's initial launch, Bank of America/Merrill Lynch, American Express, Morgan Stanley, and L.L. Bean.

He then spent a decade in healthcare marketing — first as a consultant, then on the client side as Head of Marketing within Aetna's Consumer Health Services — where he unified fragmented corporate marketing teams and led the launch of new digital health products, including one developed in partnership with Apple Health.

Today, through his consultancy, Dennis serves as a strategic advisor and fractional CMO to companies seeking greater clarity of brand purpose, stronger organizational alignment, and more disciplined marketing execution. He has also served as an Adjunct Professor at Boston University's College of Communication.
