Our nannies and mannies learn skills that take their level of expertise to a new level. Not only does a nanny or manny go through an extensive background investigation by our contracted private investigation firm, but they go through an intensive basic course that teaches them skills to provide above-average ability to protect the children in their charge.




NANNYGUARDS are trained in several disciplines, including Situational Awareness,  Advance Planning, Travel Security, Security Protocol in-house, Safety around the children, Evacuation with children, and many other Security-related drills and topics directly related to the protection of children in their charge.  They work for Royal families, celebrities, sports stars, CEOs, traveling families, and everyday average families who understand the need for a NANNYGUARD goes beyond celebrity status.
