Mark Criasia


Certifications: NAUI Course Director, Equipment Repair Technician, Instructor, Instructor Trainer, Dive Master, Dry Suit Diver, Mixed Gas Blender, Oxygen Administration, Nitrox, First Aid, CPR, AED, Neurological Assessment, Hazardous Marine Life Injuries.  I'm also certified to service, repair, and teach FFM.

My first certification was with NAUI as a scuba diver in 1972.  Although most of my diving was confined to Cape Cod and Lake Winnipesakee, I dove regularly until 1985.  When the “nest” emptied, I re-certified a few years ago with NAUI.  I’ve enjoyed scuba diving across the New England coastline and in the Caribbean.  We opened MAISI to help promote the sport of scuba diving. I am a certified NAUI/DAN Safety Instructor. I am a NAUI Lifetime member.
