mark irionMark Irion, former president of Levick and CEO of Dutko Worldwide, has joined M&A consulting firm Prosper Group in Washington as a senior advisor.

Irion helmed Dutko for 10 years and led its sale to private equity firm Lake Capital in 2003 and later to Grayling in 2009. He joined Levick in 2013 and stepped down in January.

Prosper partner David Bosses said his firm's work on the SKDKnickerbocker sale in October resulted in a spike in business in the PA, lobbying and PR sectors for consulting and M&A. He said Irion gives the firm a "greater capacity" to help clients navigate acquisitions, mergers and integrations.

Irion started out as a Capitol Hill aide.
