________________________ Broadening horizons
The success of the NYC-centric business led to a natural expansion when Atrium found itself advising on several investment transactions in Portugal from the acquisition of a rural vineyard, to industrial repositioning projects in Lisbon and continual single user investment transactions in between. Realizing the synergy with the Portugal market base, it was a natural expansion. Committed to Atrium's core philosophy the Lisbon and Porto office have been greeted with excitement by American based and European investors alike looking to expand and successfully place money in Portugal.
