If you’ve done any research into the world of accounting consulting firms, PwC’s inclusion on our list should come as no surprise. PwC has office locations across the globe, a long history of excellence, and a renewed focus on people and culture.

  • Chief Executive: Anthony Viel (CEO)
  • Specialty: Audit and Assurance; Advisory; Risk; Tax Services
  • Notable Campaigns/Clients: MetLife; Morgan Stanley; Berkshire Hathaway; The Blackstone Group; Microsoft

A usual suspect makes an appearance on the list. Deloitte is one of the most well-known consulting firms in the world, having entered the game in 1845.

The firm offers fantastic compensation, great training programs, and very interesting work.

  1. Baker Tilly

  • Headquarters: Chicago, IL
  • Chief Executive: Alan D. Whitman (CEO)
