44 years old, got NAUI certified in 1978 (age 15), became a NAUI Instructor in 1985 and because of a job I wanted, became a PADI Instructor in 1989. Still at it - diving, but no longer teaching.
Was mostly a wreck diver (rec and tech), highlight was diving the "Empress of Ireland" - Canada's "Titanic" for 6 days/2 dives a day...
Have dove the Great Lakes, off Boston (Cape Ann), a couple of flooded mines, under ice, caves in Ontario, along the BC coast and worked in Grand Cayman as a dive guide/dive master and Instructor.
Now, a tropical underwater photographer every chance I get. Off to Maui in 6 days!
