I've had the pleasure of training with Mark Soworka and Dive-Careers.com at two points in my own diving career. I first met Mark in 2003, when I went to Buddha View to do my MSDT. Mark was both professional and relaxed and I enjoyed working with him. That positive impression stayed with me, and I brought a couple of groups to Buddha View over the years as a result. Most recently, when seeking to staff IDCs, I returned to Buddha View and Dive-Careers.com. They have a regular flow of instructor candidates, and there is plenty of opportunity both to observe and learn how to conduct an IDC, but also to assist candidates with presentations, theory, and water skills, both confined and open water. Hopefully soon I'll be a Course Director, and will be able to look back on the solid foundation in instructor training I built with Dive-Careers, and have Mark to thank for much of it.
