Finnerty Economic Consulting, LLC. Testimonial
To Whom It May Concern:
My firm engaged Optimal Spaces when I searched for professional office space in New York City in 2005 and again in 2012 when the first lease expired and we decided to look for better office space in midtown Manhattan. I leased office space at 60 East 42"d Street in 2005 and office space at 122 East 42"d Street in 2012 with Stephen's assistance. When I sold my business to AlixPartners in 2014, I recommended that AlixPartners retain Optimal Spaces to negotiate a termination ofthe lease at 122 East 42"d Street.
I worked very closely with Stephen Sunderland, Senior Managing Director of Optimal Spaces, during both searches for office space as well as during the lease termination process. Stephen is very knowledgeable regarding the Manhattan office market. His advice proved crucial in negotiating two leases and securing the lease termination on favorable terms. He made himself available on short notice to view properties, and he identified a range of lease opportunities in various locations at different price points. I was able to benefit from his expertise to find suitable space without extensive searching.
I would not hesitate to recommend Stephen Sunderland and his firm to anyone who is searching for office space in Manhattan.
Very truly yours,
John D. Finnerty
