What I'm looking for

I’m looking to partner with an innovative company where I can bring confidential executive support, streamline operations, and grow professionally through new opportunities and meaningful responsibility.

I’m a highly organized, proactive administrative and executive assistant with 20+ years of experience supporting leaders in dynamic, fast-paced, technology-focused corporate environments. I’m known for discretion, integrity, and confidentiality, and for staying calm while prioritizing and completing multiple tasks with follow-through.

Most recently, I served as an Executive Assistant (Contract) at Choice Hotels Corporate Office, anticipating executive needs while managing visitor registration, office supply monitoring, and reception readiness, and reporting unusual or suspicious activity to security. At Beacon Pointe Advisors, I spearheaded improvements to the client service experience, built and implemented standard operating procedures, and streamlined workflows to improve efficiency.

I’ve also supported teams across private wealth, finance, and professional services—managing complex executive calendars, coordinating domestic and international travel, handling client-facing requests, and maintaining accurate filing and compliance systems. I’m especially proud of building reliable processes, coordinating seamless meeting logistics and video conferences, and supporting onboarding and HR communications; I’m also actively pursuing PMP as of 9/2025.
