What I'm looking for

I’m seeking an administrative, executive support, office management, or coordinator role where I can use my 10+ years of experience, strong organization and communication skills, and attention to detail. I value a collaborative workplace, professional growth, and the opportunity to make a meaningful impact.

I’m an administrative professional with 10+ years of experience supporting HR, office operations, project coordination, executive leadership, and cross-functional teams. My background includes construction/project administration, employee onboarding, document and records management, procurement, vendor coordination, compliance, travel coordination, event planning, and process improvement.

In my current role, I support HR and project operations, coordinate union employee onboarding, manage employee and vendor documentation, assist with DBE outreach and project bid requirements, coordinate company events and employee engagement initiatives, and provide executive and ownership support. Previously, I served as a Project Coordinator on the I-75 Modernization Project, where I managed purchase orders, project documentation, vendor records, expense administration, onboarding/offboarding, and subcontractor coordination.

I enjoy being the person who keeps things organized, solves problems, improves processes, and helps teams operate efficiently. I’m particularly interested in administrative, HR, office operations, project coordination, and executive support opportunities where I can use my experience while continuing to grow. I’m also currently pursuing my Certified Administrative Professional (CAP) credential through IAAP.
