MEET Andy Silverman

The CSI Team, Columbus Scuba

Andy is the founder and owner of Columbus Scuba. He got his start as an instructor with Scuba Schools International.  He then transitioned to the first accredited certifying agency, YMCA SCUBA, earned the rating of Instructor Trainer and was asked to serve on the National Advisory Committee in program development and standards while continuing as the technical advisor for the East Coast region.

In 2011, Andy received the prestigious Platinum Pro 5000 award. Only a select few of the most elite and prominent divers in the world have achieved this award. He has also been awarded ELITE 300 by PADI and is 1 of the 52 instructors out of 136,000 world-wide dive professionals to earn this award.

Andy spent almost a decade as the advisor for the diving program at International Field Studies in Andros, Bahamas which hosts the 3rd largest barrier reef in the world along with beautiful oceanic and inland Blue Holes and caves.

Andy sits on the Advisory Board for International Nitrox and Technical Diving (IANTD) and holds the rating of Instructor Trainer-Trainer and serves as a Course Director and Instructor Trainer with the most recognized training agency worldwide, Professional Association of Diving Instructors (PADI).

Andy continues to work with leading equipment manufacturers with field testing and product development.  Sidemount diving is Andy’s training passion.  He enjoys wrecks, caves and collecting submerged fossils.

Andy is blessed with a phenomenal staff and family.  Today he enjoys watching his team grow to become the most outstanding dive educators and accomplished divers that he ever could have imagined.
