What I'm looking for

I want a Chief of Staff or operational leadership role at a founder-led company where I can build scalable people and operations systems, partner with executives, and drive strategic growth while fostering a human-first culture.

I am a Certified Chief of Staff with 20 years of experience building scalable systems, leading people operations, and enabling executive teams across tech, design, and creative industries. I partner closely with founders and C-suite leaders to drive operational excellence, align strategy, and create human-first processes that support sustainable growth.

My background includes full-cycle recruiting, org design, benefits and compensation strategy, and executive communications; I have led cost-savings initiatives, launched onboarding and career ladders that reduced ramp time by 75%, and supported cross-functional GTM and branding efforts. I seek Chief of Staff or operational leadership roles at founder-led companies where I can build high-trust partnerships and operational infrastructure that multiply impact.
