About MacKenzie Barnett

As an accomplished Administrative and Executive Assistant, I bring a unique blend of precision, adaptability, and initiative to every role I take on. With years of experience supporting C-suite executives, legal professionals, and nonprofit teams, I’ve built my career around helping high-performing individuals and organizations function at their very best.Currently, I support a team of Managing Directors, Directors, and a VP at PJT Partners, a fast-paced global investment bank. My role is dynamic; I balance detailed calendar management, complex international and domestic travel coordination, event planning for 60+ people, expense tracking, and high-level internal and external communication. I thrive in environments that require foresight, discretion, and the ability to manage multiple moving parts without missing a beat.Prior to PJT, I was an Administrative Assistant at BDO USA, where I led onboarding for new hires, built strong relationships with local vendors and venues, managed firm-wide events, and provided comprehensive administrative support across multiple departments. I also oversaw internal systems like SharePoint and the NY Metro Admin inbox, playing a key role in maintaining efficiency and team alignment.My earlier roles in legal administration and nonprofit case management sharpened my communication, organizational, and interpersonal skills. From drafting legal documents and managing confidential filings to advocating for clients in the Oklahoma County Jail system, I’ve always approached my work with professionalism, empathy, and a results-oriented mindset.Colleagues know me as a dependable, resourceful team player who can handle high-pressure situations with composure and clarity. I genuinely enjoy being the person behind the scenes who makes things run seamlessly—whether it's coordinating logistics, improving internal processes, or creating positive experiences for teams and clients.I’m always open to connecting with other professionals, learning from new perspectives, and exploring opportunities where I can contribute my skills to help teams operate smoothly and strategically.Let’s connect!
