Mark Hiegel has become managing partner at R&R Partners' Phoenix office. Hiegel reports to Billy Vassiliadis, CEO, who said the appointment was the "natural evolution of the tremendous success he has brought to the company." Hiegel has been leading the Phoenix office of the Las Vegas-based independent as senior vice president for the last eight years, increasing billings in that location more than tenfold in the last decade, according to Vassiliadis.
