To whom it may concern:

I have had the pleasure of leasing office space with Stephen Sunderland of Optimal Spaces Inc. in the last two years. Steve was critical in obtaining office space for our company in a very competitive market yet at a very reasonable price. His abilities in dealing with the building owner continued even after our signing of the lease, during which time he advocated for our company. I never doubted his level of integrity. He is truly an honest broker in a field not always known for his altruism. I recommend Steve without reservation. Please feel free to call me should you need further information.

To Whom It May Concern:

Over the past year I worked very closely with Steven Sunderland as my real estate broker. My requirements for medical space was rather unusual in that I originally needed about 7,000 square feet and wound up needing double that amount. There are not too many place in the upper East Side that can meet that kind of demand.

Steve was excellent at finding and pursuing all available options. When we finally found the space, negotiations with the landlord were tricky to say the least. Steven has a calm unflappable quality that saw me through many ups and downs and despairing moments. He was always positive and worked hard behind the scenes to bring the lease to fruition.

I have only positive comments for Steve and his work. I would gladly use him again if the time ever arises and would recommend him without hesitation to others.
