Jeff has been diving with sharks across the globe since 1997. He recalls the first sight of a Caribbean Reef Shark on his first open water dive as one of the most beautiful and majestic animals on earth. “What stunned me was how peaceful and serene she was…cruising so effortlessly but with purpose, I had no fear but only admiration and respect…as I learned more about sharks through scientific research and my own experiences in the water with over a dozen different species, taking action to save them was something I had to do. Fulfilling Shark Stewards mission is a big part of my life and my identity as a human on this planet.” Jeff Morrison is a professional jazz musician and active in pitbull/bully breed canine rescue, education and advocacy throughout the United States.Contact
