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 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.

I look forward to the opportunity to utilize your company’s service in the future and wish you, and all associated with GISS a healthy and prosperous new year!

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.

Richard J. WoolleyProject Manager, HRH Construction LLC
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.
