I have had the pleasure of using Olivier DeLaurentiis and his security services on several different occasions. In every situation, whether it is public or private, he has always come prepared and conducted himself and his operation in a very professional manner. It is my pleasure to recommend his company and his services.

I would like to offer this letter of recommendation for GISS International. Due to the sale of the Helmsley Windsor Hotel, it had become necessary to engage an impartial, outside security firm to secure the assets of the hotel for the new owner. Mr. Olivier DeLaurentiis and his team of professionals, not only provided outstanding security services, but also performed in such a way as to blend in with my team of hospitality experts. Mr. DeLaurentiis went well beyond the expected scope of responsibility. He ensured that not only were the physical assets protected, but also the well-being and comfort of my guests were insured in the final days. I have only high praise and gratitude for the services rendered by GISS International.

Thank you for the outstanding level of professionalism and service that you and your staff have provided to Charles Schwab & Co. and the staffs of our NY City Metro area branch offices. During the period of 2002-2005 your services have been invaluable in helping us keep our staff secure and to manage our multiple branch office construction and renovation projects. Your assistance during special security concern situations gave our staff the comfort and reassurance that allowed them to stay focused on our daily business. You and your staff have always displayed themselves as extremely professional and caring. Your eagerness to go above and beyond the normal scope of your duties has made you and your staff like members of our own team. Thank you again for your personal initiatives on our behalf. I would be proud to recommend you and your firm to future clients. I will certainly call on you again when security services are required.

I wanted to take the time to let you know what an excellent job your company did in protecting my employees over the last month. In the brokerage business there our times that clients can become dangerous and your team responded with a level of professionalism and caring that is unsurpassed. Your team made it possible for my branch to operate as usual, without fear, and allowed us to focus on our business. Your guards were always on time, courtesy to both employees and clients, and worked hard to understand the dynamics of the situation to ensure that all possible steps were being taken to diffuse the situation. Thanks for your help and support and anytime we need protection I will be calling your company to protect us.

I would like to take this opportunity to communicate my thanks for GISS’s assistance during this year’s New Year’s Eve Event. The personnel you provided for our 1 Times Square Location were both courteous and professional. Their services were instrumental in assisting us to achieve our goal to provide a secure and safe environment for the annual “Ball” Celebration. Please convey my special “THANKS”, to Mr. Michael Mascia, who was on-site during the critical times and provided the “backbone” of the service that GISS provided. His contributions and professionalism must be commended.

Over the past few months, our offices have undergone extensive renovations and inconveniences as a result of construction activity in our building. We were displaced from our offices and placed into temporary trailers for the summer months. GISS International has been the on-site security company here during this chaotic and stressful period for our operations. I would like to commend you for the top-notch employees that you have sent to work with us, in particular Vince Campbell and Robert Shannon. These employees have been exceptionally patient, accommodating, and have extended themselves to make us feel as comfortable as possible in our constrained environment. Recently, we have moved back into our offices, and still they persist in providing superior customer service. As I have grown to know, and I am sure that you know that you possess quality employees working for your organization.

The High Holy Days were just days after the tragic events of September 11th. The presence of you and your staff helped our congregants feel more at ease during those tense days. I have found your staff to be professional, courteous, and willing to accommodate above and beyond what I would come to expect from a security company. Thank you for allowing me the opportunity to express my satisfaction with your company.

GISS International has been a security service firm for HRH Construction, LLC since 1998. GISS has recently performed site security services for HRH under my direction during the construction of two 20-story residential apartment buildings in White Plains, New York and we look forward to calling upon them in the future for additional services. Both their office and field staff are very courteous and respectful. Their people always report to work on time and always meet our difficult site security requirements 24 hours a day, 7 days a week as needed while acting in a professional manner. Furthermore, Mr. Olivier DeLaurentiis is nothing short of a pleasure to work with.
