Jim Estabrook started diving when he was just a kid and quickly discovered that it was something he wanted to be involved in his entire life. We do work with the universities in Boston, locals who are interested in scuba and also different public safety organizations in the Northeast. We have been with many different agencies in the past, but choose to now teach through SDI. We feel that the standards and course materials available through SDI, along with our quality instruction, produce the best, and safest, divers. You can visit their website here!
