Profile bio

About Marissa Tree

Over my 20+ year career, I have created and led countless fully integrated communications, public relations and public affairs campaigns for some of the most well-known public and private companies in some of the world's largest and fastest growing economies, from Australia to Asia to America. These include many game-changing and change-making B2B and B2C brands, such as Celonis, Zendesk, NetApp, Mastercard, and Coca-Cola in order to define, elevate, promote and protect their brand. As a global communications leader, I am known for quickly developing trusted relationships across all levels of a company and teams of all sizes grounded in transparency, integrity, momentum and results, particularly with C-Suite and executive leadership, by creating high-impact internal and external communication strategies that solve business challenges, drive growth and build reputation.I am particularly proud of the global teams I have built and galvanized around shared goals that are focused on driving consistency and clarity in the way a company communicates. This has resulted in near zero team attrition, and promoting all my direct reports in all my roles to date.I am also a dedicated equestrian (restarting a 13yo off the track thoroughbred) and fashion model (trained by Coco Rocha).

Listed skills include Marketing Communications, Media Relations, Event Management, Public Relations, and 35 others.
