Inhouse dive team
Johanna Strömgren - Marketing/Diver
Johanna has more than 25 years of diving experience. She has been a scuba instructor and instructor trainer for many years. Johanna dives mostly in Swedish and Norwegian waters, but she also has a lot of experience of diving in tropical waters. Johanna likes to watch "underwater creatures" during her dives. She enjoys wreck diving - when the wreck is also an artificial reef full of marine life. Johanna is part of the team conducting tests and development of SI TECH products.

Steve is managing the injection molding process at SI TECH. When he's not taking care of the machinery at the factory he spends time with his Dræger Dolphin rebreather.

Steve is part of the team conducting tests and development of SI TECH products.
