McKinsey held onto the top spot for the third year in a row, matching Bain's 2011-2013 run. BCG capitalized on these lower scores by moving into 2nd. Overall, Booz Allen Hamilton was the big winner, jumping 15 spots to rank 6th. Clearview Healthcare Partners also orchestrated an impressive move in 2020, climbing 13 spots to 24th. Cornerstone made the splashiest debut at #25 as the Brattle Group tumbled out of the Top 20 altogether after ranking 10th just two years ago.
