Sapphire Office Solutions Testimonial

Sapphire Office Solutions testimonial To Whom It May Concern: I am writing this letter of recommendation to acknowledge the outstanding job performed by Mr. Stephen Sunderland of Optimal Spaces, Incorporated, in regards to locating and executing a great sublease and direct lease extension. In addition to finding the sublease, Stephen also add a long term extension to our direct lease at a great price. We never would have completed this transaction without Stephen's persistency, expertise, and diligence. We attempted to work with other brokers prior to meeting Stephen (discovered Stephen from advertisement) and he was the only broker who listened to our needs and took us to spaces that fit all OUR requirements, not his. We would highly recommend Mr. Sunderland and his company without hesitation. Sincerely, Paul Holstein President
