To Whom it May Concern:

I have had the opportunity to work with Optimal Spaces Inc. (specifically, Stephen Sunderland) over the last 18 months. In 1999, 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,

To Whom It May Concern,

Stephen Sunderland and the team at Optimal Spaces Inc. Inc. have handled a number of transactions for Belzberg Technologies in New York, Philadelphia, and Chicago. In New York alone, Optimal Spaces Inc. recently saved us almost a million dollars by finding a fully built data facility when we were about to build one.
The team at Optimal Spaces Inc. was personable, hardworking, trustworthy and was able to both quickly and effectively determine our needs and find the appropriate solution. Belzberg Technologies continues to use Optimal Spaces Inc. for all its real estate needs and I would highly recommend their services to anyone attempting to navigate the commercial real estate market in New York.

Please feel free to contact me at (212) 943-1400

Dear Mr. Sunderland:

Thank you for the outstanding service you gave to us as we searched for office space.  Through your efforts, you found us a location and facility that is virtually an exact fit for our needs.  You helped us with the lease negotiations and were able to procure the space at a very attractive price.  In short, you got us a great deal!

You went above and beyond the call of duty in working with us until we moved in.  You were always accessible and prepared to help us in every way.

We would highly recommend you to our other friends and colleagues in their search for best available/best fitting space for their needs.

Very truly yours,

Donald Krueger
Chief Financial Officer.

To whom it may concern:

I am writing to recommend Stephen Sunderland and Optimal Spaces Inc. for the excellent job they did in finding us a sublease at 29 West 57th Street. They were fast and efficient in locating spaces that met our needs and corporate image, aggressive in negotiating on our behalf, and effective in communicating our needs to the landlord and getting our offer accepted.

I look forward to working with the team at Optimal Spaces Inc. again.

Very truly yours,

Robert Miller
Co-Chairman

To Whom it May Concern:

This is to give reference for Stephen Sunderland, who provided commercial real estate brokerage services to our firm, Double Agent. His work led to our signing of a five year lease and five year optional extension on 6,200 square feet of SOHO office space at a very competitive rate.

I was extremely impressed by Stephen's professionalism and follow-through in helping us not only locate this space but also in bringing it to closing. He showed a good knowledge of our needs and through that avoided wasting our time showing us unsuitable properties.

I would be glad to provide further reference for Stephen and you may feel free to call me about him. I can give him an unqualified recommendation.

Best regards,

Andrew Szabo
Chairman and CEO
Double Agent, Inc.

To Whom It May Concern:

We had the pleasure of working with Stephen Sunderland months ago when we were in search of new office space for our growing company. He was of great assistance with all the questions we had about today's real estate market. His accurate analysis of the market and the time he took to listen and understand our motivations was a great advantage We required an office building that would allow us to expand and support all of our companies needs.

Stephen Sunderland walked us down every road we needed to go and many times paved the way making it easier on us than could have been expected. He advised us and guided us through all the steps. He worked with us closely and made sure that he knew exactly what we were looking for. He provided us with real estate options and solutions that would save us both money and time down the road as our company grew.

His dedication and commitment to his clients are rare commodities in today's self-interested world. If you see fit to give him a chance to serve you, we guarantee, you'll never look for another real estate agent. Without reservation, we strongly recommend the services of Stephen Sunderland and would most definitely work with him again, if his assistance is called for.

If we could further assist you, please do not hesitate to contact us.

Sincerely,

S. George Miller

Dear Stephen,

We would like to thank you for your assistance in helping us to arrange a sublet in Olympic Tower. My partners and I were determined to sublet a space that was fully furnished and equipped to our specifications at a fair market value. We utilized several different brokers, but we found that only you consistently found new sublet opportunities for us during the entire year of our search. When we began our search, prices for Class A office space in the Plaza District ranged from $80-150/RSF, by the end of our search the prices had fallen to $50-$85/RSF. Your hard work and tenacity at finding new listings allowed us to find the ideal space at the right price in Class A. Thanks for sticking with us.
Sincerely,
Elias Saal
