In 2002, he joined the upstart Ring of Honor promotion, where in 2004 he formed a heelstable known as The Embassy. In storylines, Nana used his wealth gained from the taxes of people of Ghana to hire wrestlers to wrestle his opponents and rivals. Under his management John Walters defended his ROH Pure Championship and Jimmy Rave, Alex Shelley and Abyss won the Trios Tournament in 2006. He remained with Ring of Honor until September 2006, when he gave his notice. On October 24, 2008, in Danbury, Connecticut, Nana made a surprise return to Ring of Honor, saying he has no more riches, no more crown, and just wants a job before he was dragged away by security. The next night, Nana made an appearance at Ring of Honor's Edison, New Jersey show and did the same thing. Again, he was dragged away by security. The next time ROH was in Edison on January 17, 2009, Nana again appeared, only to be dragged away by security. He has since been featured in segments on the ROH Video Wire. In a March edition of the ROH Video Wire, Nana revealed that he had regained his riches due to President Obama's stimulus package, and has been directing Bison Smith's attacks on ROH wrestlers. On March 20, at the ROH show in Elizabeth, PA, Nana declared that he had officially reformed the Embassy, with himself, Bison Smith and Ernie Osiris. The next day in New York City they were joined by the returning Jimmy Rave. Other members of the stable came to include Claudio Castagnoli, Joey Ryan, Erick Stevens, Shawn Daivari and Necro Butcher, but by October 2010 all of them, except Osiris, had left the group. On January 22, 2011, Nana debuted the latest version of the Embassy, consisting of Ernesto Osiris, Mia Yim, R.D. Evans, and Tommaso Ciampa, who would take over Jimmy Rave's former role as Nana's number one wrestler. The following April and June, both Dave Taylor and Rhino made appearances representing the Embassy. On the July 28 episode of Ring of Honor Wrestling, The Embassy disbanded, when Ciampa turned on Nana, after R.D. Evans had revealed his deal with Truth Martini, which had cost Ciampa the ROH World Television Championship. On Monday June 3, 2013, Nana received a tryout with WWE, Nana commented on the tryout on Facebook, writing, "Great day with the WWE...The future may be bright....Fools." In mid-2013, Nana was given the new on-screen role of ROH Talent Scout. In late 2014, Nana formed yet another version of the Embassy with Moose, Stokely Hathaway and Veda Scott, which was later disbanded. Nana was the manager of Donovan Dijak, after he sent him some envelopes every time he wrestled, until he finally departed from The House of Truth that took place on February 25, 2016 episode of ROH tapings.
