TPG Rewards Testimonial

TPG Rewards testimonial To whom it may concern, This letter is written in support of Mr. Stephen Sunderland. Mr. Sunderland acted as our advisor and broker in our recent search for office space in Manhattan. From our first meeting Mr. Sunderland sought to understand our location, price, office layout and square footage needs. He closely accessed our initial needs, and made realistic suggestions to improve on them. The true measure of Mr. Sunderland's professionalism is that he delivered listings, and ultimately a deal, that closely related to our initial wishes and needs. Throughout our relationship he gave us sound advice as to the pros and cons of each location, and later on how to best work with the landlord in order to create an amicable deal. Mr. Sunderland is a knowledgeable real estate professional who I recommend without any reservation. Sincerely, John S Galinos,President and CEO, TPG Rewards Inc, 111 John Street,27th Floor New York, NY 10038.
