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.

Thank you for choosing Columbus Scuba, and congratulations on choosing diving as your next endeavor.  Diving has been such an important part of my life, on a physical, social, and even spiritual level. 

Diving has allowed me to travel the world from Southeast Asia – Australia, Philippines, and Indonesia to the caves of North Florida and rock quarries in the Midwest.  I’ve had the opportunity to search for fossils in South Carolina rivers and dive with my amazing children in dozens of the beautiful islands of the Caribbean.

It’s been said, “Scuba divers are the only true explorers left on earth.” While the vast majority of earth is covered with water, we have only tapped into a small percentage of all available to be explored.

The ocean has a very similar composition to that of man, yet we know so little about what really lies beneath the surface.  The fact is that just about every living land organism has originated over time from the ocean.  The ocean is constantly moving and changing both over long and short periods of time.

Some depths have not yet been reached, and there may be life that has not yet been identified.  There are shipwrecks, rich in history, that have disappeared and are waiting to be uncovered, and caves that riddle many of the landmasses we walk on that appear never to end.

Underwater exploration dates back thousands of years and has evolved into a giant industry today.  Many men and women have devoted their lives to exploring the aquatic world, and some of their lives have even been lost due to their perseverance.

What we do know is this…. The ocean is beautiful and the ocean is spectacular.  Diving is the catalyst to exploring the variety of aquatic environments that lie right at our fingertips.   Columbus Scuba welcomes you to begin or continue your journey to visit this mysterious underwater world. 

My “journey” is far from over and what drives me most is sharing it with my friends and family!   Come join our amazing family and you’ll see exactly what I’m describing.   We look forward to diving with you!

Best regards and safe diving!
Andy Silverman
Owner and Dive Educator

What sets Columbus Scuba apart is the culture that we’ve built.  What we do underwater is wonderful but a great deal of the magic happens topside.  

There is no secret that the Columbus Scuba family continues to grow year after year regardless of the economy or current events.  So many of our customers have really found a place to call their “family” and we’ve seen relationships build, marriages form and even children born as a result of this family feel. 

Camping and cookouts at the quarries throughout the summer months bring an entire new dynamic to diving.  Columbus Scuba divers rush to the quarry every Friday afternoon to connect with our diving family, carrouse around the campfire and welcome the next new group coming to get certified.  Its an amazing experience to watch this in motion.  

Other stores, dive operators and training agencies have asked “how do you do it” and my response has never changed since I initiated Columbus Scuba.  “I havent done anything. It’s the people we’ve attracted, you just have to come out and experience it for yourself to understand”. 

It is the personalities of Columbus Scuba that make it what it is today.  Some have been with me since 1999 and some are just joining us.  Some have moved on to the military, sought jobs in diving internationally or have been relocated due to their careers.  Regardless, they will always have a place to call home and we always look forward to seeing them when they return.  

Somehow, Ive been connected with some of the most caring and energetic people I could ever hope to call my friends and have on my team.  It’s a beautiful thing and we always look forward to meeting the next great person to join us.  

See you out diving!
