About

I am a people-focused leader with over 20 years of experience developing managers, strengthening teams, and building organizational capability across healthcare and technology environments. While my career has been rooted in operations, the core of my work has always been people - coaching leaders through performance challenges, navigating complex employee relations issues, and creating cultures where teams are clear, supported, and empowered to succeed. I bring deep experience in performance management, employee development, manager coaching, and HR operations. I've led HR functions, managed teams across the revenue cycle and clinical operations, and partnered with leaders to handle difficult conversations, build accountability, and drive engagement. What sets me apart is my ability to understand business operations while staying focused on the people side - I know what managers need because I've been one, and I know how to build HR solutions that actually work in real operational environments. My leadership style is grounded in trust, accountability, and genuine care for people. I believe strong cultures are built through clear expectations, thoughtful coaching, and treating people as individuals, not resources. I'm currently pursuing my PHR certification and focused on deepening my HR expertise.
