Founder & Principal, Sage HR Advisors
Stefanie founded Sage HR Advisors to deliver strategic and operational HR support for hedge funds and investment management firms, with a focus on smaller firms and start-ups that need experienced leadership without a full in-house department.
She partners directly with leadership teams across payroll and benefits administration, onboarding and offboarding, compensation planning, employee relations, policy development, and performance management.
Stefanie also supports transitions such as M&A due diligence and post-acquisition integration, helping firms align systems, policies, and culture while maintaining compliance and clear communication.
