Jim Marquette is our PADI IDC STAFF INSTRUCTOR Originally from Michigan, he has decided enough with the cold water diving of the Great Lakes for the much warmer water of the Florida Keys. Jim started his diving career back in 1983 while serving with the US Marine Corps. Became a PADI professional 15 years ago and really enjoys teaching people to become ambassadors of the sea. Jim’s passion with photography keeps him busy underwater as well as on land. When he is above water you will find him around the marina, out and about with his camera or out riding his Harley.
