Per Jennische has been a full-time SSI Freediving Instructor since 2015 and became an Instructor Trainer in 2017 after training and certifying more than 300 students. Per was born and raised in Sweden but spent the last eight years in Asia where he also underwent his professional training. He just recently returned to Europe where he is settling down with his girlfriend to develop freediving and yoga on the Mediterranean island of Mallorca. There he has partnered up with Actionsport Prodive Mallorca to offer everything from beginner to instructor courses.
For Per freediving is as much a way to enjoy and explore the underwater world as it is a way to explore yourself and your abilities.
