Connect with me on LinkedIn at barbarazerbe I help businesses navigate chaos and achieve growth through effective project management, streamlined operations, targeted marketing strategies, and impactful coaching. I am extremely organized, relish the planning process, and enjoy productivity apps. I have created, implemented, and monitored project management systems utilizing Basecamp, Asana, and Trello. My past graphic design experience has kept me well-versed in Adobe Creative Suite. I have experience with Excel, Google Docs, Pages, Powerpoint, and Keynote. One of my strongest assets is the ability to balance a creative mind with a drive for organization and process. I am also an excellent leader in cross-functional team environments; I garner respect and navigate conflicts for optimal collaboration. Project management goes far beyond a proclivity for planning. My unique qualities beyond experience and education are emotional intelligence, soft skills, and work ethic that are difficult to teach or instill in a project leader. I scored highest in responsibility, structure, flexibility, endurance, control, and composure. PROFESSIONAL HIGHLIGHTS • Launched the NY Times and Amazon Best-Seller Reversing Alzheimer’s by Dr. Heather Sandison overseeing marketing, project management, and public relations, including the marketing and launch of the quarterly Reversing Alzheimer’s Course. • Implemented organization-wide Asana Project Management systems for HealthMeans, Chris Kresser and other clients.
