Wally Manderson

SDI Dive Master

Brett, aka Buster, got the diving bug while snorkeling on vacation in Cozumel. Upon arriving home he immediately contacted Mary and Dave to take the plunge. Brett enjoys traveling and diving all over the world with his wife and diving partner Diana and his extended Blue Marble family.  Brett's other hobbies include restoring old cars and making some of the best pizza, (a leftover from a former occupation),

​Justin's Bio coming soon
“Warm Water” Wally is…well, he’s just mean. That’s said with the utmost admiration and respect, but doggone it…he’s just mean.  But when you’re as big and intimidating as he is, you’re allowed to be mean and it’s a kind of meanness that most people aspire to be.  It’s a “tough love” kinda mean.  He’ll tell you not ascend too quickly and he’ll tell you in a way that you won’t want to disappoint him.  He’ll tell ya to keep an eye on your buoyancy and you’ll do it because you’re not quite sure if he is watching you or not. But he tells ya these things cuz he cares.  Everyone that knows him knows that his hard exterior shell houses a big softie.  I think.
"Mother Hen" Mary, often considered Dave's partner in crime, began her career diving naked for a local nationally renowned aquarium. This attracted tourists from all over the world and effectively doubled the revenue for the aquarium during her 5 year naked-diving tenure. It wasn't until Dave discovered this talent and kindly explained the true meaning of skin diving did Mary leave her high-profile position and become Dave's teaching assistant and dive buddy. Together they have shared many a diving experience. Mary co-ordinates all of our travels, making sure all of the smallest details are covered. If you're looking for a dive vacation let Mary put together a package for you, the only thing you'll have to do is enjoy yourself.

"Deep Diver" Dave has been a Scuba  Instructor for over 140 years  and has certified over 10,000 divers of all ages and levels. Okay, maybe those stats are a little skewed, but they're not that far off the mark.  After discovering the amazement and excitement brought forth from being able to breath underwater, Dave was hooked.  He started traveling about the country in his beat-up Volkswagen van playing guitar in smoke filled bars trying to earn enough money to continue with his diving lessons. 

Seriously, Dave loves to share his passion for the underwater world.  After over twenty years teaching his greatest joy is the look on peoples faces once they take their first breath on Scuba.  His diving adventures have taken him around the world, from the Caribbean to the far east. Dave is an accomplished underwater photographer having won several honorable mentions in photographic competitions and his work has been published in magazines and books.
