Argent Trading Testimonial

Argent Trading testimonial To Whom it May Concern: I have had the opportunity to work with Optimal Spaces Inc. (specifically, Stephen Sunderland) over the last 18 months. Stephen was hired to find a reasonably priced lease for corporate office space that would support our highly professional environment. I considered this to be a significant challenge since Manhattan was experiencing a severe shortage in available professional space. However, Stephen found a space that exceeded my expectations and that was approximately 15% below current market rates for comparable space. An important aspect of working with Stephen is the level to which I can trust him to act in my best interest. I believe that Stephen possesses in-depth knowledge of the New York City real estate market and is responsive and performs his work in a very professional manner. I am impressed by Stephen's sincere desire to understand his clients' needs. It is clear to me that Stephen is interested un building mutually beneficial business relationships. I am happy to recommend Optimal Spaces Inc. to other growing businesses, and I look forward to working with Optimal Spaces Inc. again. Sincerely, William Levitz President Argent Trading, LLC
