Mark Jeffrey is the award-winning co-founder and CEO of Guardian Circle, a service tackling an extremely critical industry most of us take for granted… emergency response. Guardian Circle will support the six BILLION people worldwide and in developing countries, who have no emergency services at all -- particularly women in countries like India
