We would like to take this opportunity to thank you for your excellent service in finding a new office for our company, Red Apple Group.

We appreciate that your team was always available to review thoroughly with us all leasing and acquisition options for our relocation. We also appreciate our continued relationship with Prime Manhattan. Your team has proven to be a great resource for local market knowledge, comparables and new deals.
We have recommended your firm to others for office leasing. We look forward to doing future transactions with your company.Bill, there were two points we relayed to you; the budget and the importance of image. You were successful in achieving satisfaction for both!
