"I partner with business leaders, founders, and entrepreneurs to drive sustainable growth by enhancing efficiency, strategic planning, and organizational structure. My approach focuses on three key areas: optimizing core business processes for maximum efficiency, building 3-5 year strategic plans with actionable steps backed by financial modeling, and developing organizational structures that align teams, verticals, and administration with future goals. By integrating these elements, I help businesses scale effectively and achieve their long-term vision."
