SZILVIA GOGH



Szilvia Gogh started scuba diving when she was 13 years old (quite some years ago), as a member of a dive club in
Budapest, Hungary.

 

As a diver she competed in orienteering diving for several years. Orienteering consists of finding buoys
in low visibility lakes with the use of a compass and a distance counting device.

 

It was a long journey from being a competitive orienteering diver in Hungary to becoming a PADI Course Director. It was an exhilarating accomplishment for her because she was the youngest female Course Director world-wide ever excepted
into this highly respected program. She is still the only female Hungarian Course Director.

 

Since she started diving she has logged 5000+ dives. As an instructor she has certified over 1000 divers
from beginners to dive professionals including special training for the LAPD as well as Sheriffs and Fire Departments.

 

As a PADI Course Director, and expert in navigating underwater, she serves as a trainer for new divers and for
the very experienced, such as the LAPD Search & Rescue Dive Instructors.

 

She works in front of the camera as an adventure show host as well as a Stunt Women in blockbuster Hollywood movies
and TV series. She provides Water Safety and trains actors to breath underwater when working on the set.

AUTUMN BLUM


Growing up in Sarasota, Florida, Autumn has always been passionate about the outdoors. She became a NAUI certified
diver at 14, and spent her youth diving, backpacking and kayaking the Florida rivers. More recently, she’s become a
rebreather diver, underwater photographer and PADI SCUBA Instructor.  In 2014, Autumn founded Scuba Girls to provide a safe and fun environment for women to learn, travel and dive. www.scubagirls.com  Autumn is also the founder of

Quick to catch a chill, Autumn moves from her 3 mil wetsuit right into her custom Mobby’s drysuit when the water
temperatures drop below 78F.  “I’ve never been an ‘off the rack’ woman, and never found the right fit with a wetsuit or
drysuit.  Choosing the custom colors was fun, but Mobby’s quick custom fitting process finally gave me the best fit I could
have hoped for.

A cosmetic chemist, environmentalist and ecopreneur, Autumn has been able to combine her passion for the underwater world with her career.  When not in her office in rural central Florida, she can often be found diving in the Florida Keys,
training local dive centers about sunscreens and body care ingredients, or leading a Scuba Girls expedition to another
exotic location, always with her Mobby’s gear.
