Ronald M. Druker's House

Druker has 50-odd hotels and apartment buildings he owns or manages. Druker, whose father built the Colonnade, has added to the family portfolio with the Heritage on the Garden and the Colonnade Residences, once home to Kevin Millar and Trot Nixon. And he sold all 103 luxury condos in his critically acclaimed Atelier 505 (at prices of up to $3.3 million per) five months before it opened.

In 2006 he was ranked the 37th richest Bostonian at $400 million.
