Background

About Rayann Castro

I have been a part of National Services Group for 18 years, starting as an accounting administrator and working my way up through team lead and into my current role as Administrative & Accounting Operations Manager. Along the way, I’ve learned how much I enjoy both the operational side of running a business and the people side of building a team. My career has been defined by a commitment to accuracy, efficiency, and process refinement. I excel at identifying gaps, streamlining workflows, and implementing improvements that strengthen financial and administrative operations. I thrive in fast-paced, high-growth environments, adapting quickly to company needs while maintaining accuracy and compliance in financial and administrative workflows. Equally important, I bring a people-first leadership approach - mentoring, onboarding, and supporting team members in their professional growth, while fostering accountability and collaboration. I take pride in building systems and teams that not only meet business demands but also contribute to long-term organizational success.
