The Safety and Security of you and your family, business and employees during these uncertain times is of the utmost importance and a daunting task in and of itself.  The current work of ISA overwhelmingly demonstrates that there is no alternative to collective actions of the international community on maintaining peace and security.  ISA has always been a leading advocate in resolving this vital task.  In recent years counteracting such major threats as international terrorism, escalated gang violence, nuclear armament and kidnapping has overshadowed the topical issues of safety and security natural and manmade emergencies and disaster response.  Second and Third World Countries containing a possible aggression for increased international recognition and status; striving to achieving supremacy over neighbors, and, possibly, gaining economic benefits are the factors that incite a number of countries to obtain such weapons, and implement wide scale military programs.

ISA is here in Texas, the RGV to provide the peace of mind we all want and deserve that is why I am here and why ISA is the wisest choice for our cities, communities, you, your family and your business.
