Hi, I’m Crystal.
I know firsthand what it takes to excel at the highest levels of executive support because I’ve lived it. For over eight years, I served as Chief of Staff and Lead Executive Assistant to a high-profile entertainment and media executive, navigating high-stakes demands, orchestrating major events, and becoming the trusted partner executives and celebrities counted on.
But my expertise didn’t begin there. In 2009, I founded Write to Success, a resume writing and career development company that has helped countless professionals land opportunities, elevate their personal brand, and take the next step in their careers. Guiding others to present themselves with clarity and confidence has been my passion for more than a decade.
Through Crystal Marshall Certified, I’ve combined both worlds—my experience supporting top-tier executives and my long-standing work in career advancement—to create the Pinnacle Collection. These modules reflect the skills that defined my own success: executing flawless events, building powerful resumes, staying coachable and adaptable, and developing the deep insight needed to truly know and support your boss.
I designed this collection for assistants who want to go beyond “good enough” and step into the role of trusted advisor, problem-solver, and leader. If you’re ready to operate like the best of the best, the Pinnacle Collection will give you the tools to get there.
