Melissa Castillo

I’m an Operations Manager and Executive Support Professional with 8+ years of experience overseeing organizational operations, supporting executive leadership, and improving administrative processes across nonprofit and educational environments. I coordinate strategic projects, maintain strict confidentiality, and build reliable systems that help teams move faster with fewer operational friction points.

In my most recent role, I served as the primary operational partner to the Executive Director, managing executive priorities and ensuring smooth day-to-day operations. I handle executive calendars, meetings, travel logistics, reports, presentations, and confidential correspondence, while also coordinating organization-wide projects and balancing competing deadlines.

I focus heavily on compliance and operational consistency—developing administrative systems, managing confidential personnel, financial, and client records, and ensuring requirements are met. I also act as a trusted liaison between executive leadership, staff, government agencies, vendors, donors, volunteers, and community stakeholders, including onboarding, documentation, and administrative support.

Before that, I led in education and school administration, including instructional planning, student records and attendance documentation, and policy-aligned compliance. As a School Administrator, I led daily operations for a school of 150 students and 10 employees, improved efficiency and communication, supported budgeting and planning, and achieved 100% retention over my 2 years of leadership.
