Introducing Your Future Friends

HI!  Welcome to St. Croix and Sweet Bottom Dive Center.  We are glad to have you and are looking forward to diving with you soon.


Our staff of professional scuba instructors are experts in every type of diving imaginable here on St. Croix.  We could even teach you some ice diving...if we had ice.  As certified PADI Instructors we can conduct almost every certification available from our beach front dive center.  If you're making the run to warmer waters to finish your Open Water certification, want to learn how to take beautiful underwater photographs, or even become a professional dive master we can do it all for you.


Here at Sweet Bottom we focus on the fun and relaxing parts of the diving.  Whether you're on a full blown 5 dives a day adventure or just feel the urge to catch a quick dive, we'll help to make every moment count.  Don't you worry about a thing either because we are more than happy to put together, carry, break down, clean, and dry your gear after each and every dive!  Just relax and enjoy the underwater view off the closest dive site to "The Wall."


So let's meet your future friends...

Tim Linse

Shop Manager

Technical Diving Instructor


Diving became a career and passion for me in the cold waters of Lake Michigan diving the wrecks off Chicago. Soon after my first few breaths on SCUBA in 2008; I worked my way up to become a shop manager in a large dive center, and taught as a technical instructor in my hometown of Chicago. When the time came to move to St Croix, it was an easy choice (Warm Water, Great Vizz, and Deep Depths! No Brainer!)

My favorite things to do in STX are long exploration dives on "less known" dive sites along the island.. the DPVs and CCR make this managable and quite enjoyable.

In the future, I hope to continue my education as a Paramedic/Fire Fighter and run the dive team. My non-diving hobbies are making beer (the hoppier the better), rock climbing, skiing, and planning the next big DIVE :)

Lizzi Schader

Shop "Go-To-Girl"

Dive Master Candidate


I moved down to St Croix to start a new adventure in the Scuba Industry.. With a past resume' of Early Childhood Education, Swim Instructor, and Lifeguarding this change was a BIG one. I have been learning so much about diving and how to ensure all our divers have the best possible time while in our care.

I started diving back in 09' because I needed the certifcation for an internship with the Miami Seaquarium. Soon after, I found my greatest joy, diving!

Other than diving, I love swimming, rollerblading, tennis, soccer, & watching the Chicago Blackhawks!

Mark Linse

Director of Training

Course Director


During my 28 years of diving, I have had the opportunity to travel and dive in many different locals and dive environments…whether I was diving on the beautiful coral reefs of St Croix, the massive wrecks off of Lake Michigan, Key Largo or Fort Lauderdale, swimming with the dolphins in Curacao, playing tag with the baby peacock flounders in Bonaire, dodging the 12' bull sharks in Fiji or swimming inside a school of barracudas in Malaysia, my dive adventures are always fun and exciting.


During my 30+ year career as a Chicago Paramedic and EMS Educator, I have had the opportunity to hone my instructional and presentation skills.  What a perfect fit to take that experience and combine it with something I truly enjoy sharing with others…scuba diving!


As a dive educator, I can hold your hand during your very first breath underwater, or I can train you in unique underwater skills, such as; advanced navigation, search and recovery, sidemount diving, full face mask and dry suit diving, just to name a few.  I can mentor you into leadership roles, as you learn the information and skills necessary to become a PADI Divemaster.  Or, I can help you change your life forever; as I lead you down the path of becoming a PADI Open Water Scuba Instructor, Specialty Instructor, IDC Staff Instructor or I can even mentor you, as you prepare to become a PADI Course Director.


My passion lies with people.  I enjoy sharing my knowledge and experiences with people, but more importantly, I love learning about you…your passions, your experiences and your dreams.  Scuba Diving has a HUGE social component to it.  Anyone, can teach you how to tie a bowline underwater…let me get to know you and see if I can't help you realize your dreams.

He is a Physician Assistant, works in the Emergency Department at Juan F. Luis Hospital and Medical Center on St. Croix and is an Assistant Professor and the Associate Director of Medical Education at the Barry University Physician Assistant Program, St. Croix Campus.

Bill Colderbank

Master Scuba Diver Trainer


In 1964 Bill's father met an ex-navy diver that was teaching SCUBA at the local YMCA. Dad signed Bill up for the class and he's been diving ever since. Bill received his Master Scuba Diver Trainer (MSDT) certification in 2004. When he's not teaching scuba diving, Bill manages the logistics for an international marketing company.


Bill has had the opportunity to dive in exotic locations for over 40 years. He experienced a perfect "Kodak" moment on New Years Eve 2001 while he was on the surface waters off the coast of Bonaire with his dive group. There was a full moon overhead, and as he was waiting to descend he and his dive group watched the sky light up with the island's beautiful fireworks display.


Other than Bonaire, Bill's favorite dive locations are the Galapagos Islands to see a display of large sea life and St. Croix, USVI to observe smaller marine life and healthy reefs.

Bailey Rowland

Open Water Scuba Instructor, Specialty Instructor


Bailey is from the close-knit beach town of Atlantic Beach, FL. Thanks to her dive-crazed parents, she was certified at the ripe age of 11 years old. Since then she has been diving in Jacksonville, Little Cayman, Grand Cayman, Belize, Curacao, and of course St. Croix! It has been a dream of hers to be a dive professional since the first time she took a breath underwater.


After graduating from Florida State University in 2011, she decided she wanted to take the road less traveled. On a family dive trip to St. Croix in 2012 she instantly fell in love with the island, Sweet Bottom Dive Center and its managers Mel and Greg. On that same trip, Bailey's mom mentioned that if she was young again she would move to St. Croix to become a dive instructor. A light bulb went off and a year later Bailey made the move to the island!
