About me

More than 20 years leading payroll and HR operations.

I grew up in a family of entrepreneurs and first planned to become a doctor. Life pointed me toward business instead, and I found my place in HR and payroll operations, where the details decide whether people get paid correctly.

Since then I've managed and directed payroll, HRIS, benefits, leave, HR operations and compliance. I've built HR operations from the ground up, replaced and consolidated HR systems, run payroll across states and union contracts, and supported mergers, acquisitions and audits. Today I lead that work for a large global organization in a hyper-growth phase, with multiple companies under one umbrella.

I work extensively with AI, both using it in payroll and HR work and teaching people how to use it, and my knowledge of it keeps growing.

I started Hartigos Consulting Group to take that administrative weight off your team, with solutions built around how your organization works.

No challenge is too big or too small.

Where I've done the work
  • Large global organization, hyper growth

    Direct payroll, HRIS, benefits, leave, HR operations and compliance across multiple companies under one umbrella during a period of rapid growth.

  • Small retail business

    Helped the business grow and became its People and Business Operations Director.

  • Multi-state non-profit

    Replaced the HR technology suite with one HRIS for 9,000+ employees, revised handbook compliance sections and documented SOC 2 controls with legal and external auditors.

  • Public manufacturing companies, unionized

    Consolidated four HR systems into one, oversaw payroll and operations, and supported mergers, acquisitions and succession planning.

  • Local credit union

    Compensation, benefits and financial operations on a small HR team, including COVID-era regulations.

  • Insurtech start-up

    Built HR operations from scratch, launched the company's first HRIS and integrated 31+ benefit vendors, with exposure to global HR.
