I have always been fascinated with Scuba Diving, and while on vacation with my wife in the Caribbean, I finally got my opportunity to give it a try. I was immediately hooked after my first venture into the ocean. Diving in the Caribbean is my favorite location, and I especially love St. Lucia, as the water is warm, clear, and has plenty of sea life.

As an instructor, I love showing new divers the thrill of scuba diving. My favorite thing is seeing a new divers look on their face after they take their first breaths underwater. There’s nothing better than seeing that big smile as they come up from a dive and witnessing their sense of accomplishment and excitement.

Come by Salt & Sea Scuba and let me share the excitement of scuba diving with you.

I first started diving professionally in 2012 while living in Croatia, I have been an instructor full time ever since. I have been diving throughout the world and love to find off the beaten path type of places to dive. The last three years I have been able to lead a small dive team in exploring an underwater tomb in Sudan (Flooded Tombs of the Nile – NatGeo/Disney+).

Diving to me can be as peaceful and easy or, as adventurous and epic as you want. Not every dive has to be the same. I love introducing people to different types of diving and new places they may not have even considered.

Patrick Hammer

Course Director

I started diving when I was a teenager and in college began teaching SCUBA. I know then that I wanted to do this the rest of my life. When I opened my first store in 1974, my friends and family thought I was goofy because I was so far away from the ocean. When asked where would you dive here I Chicago, I said that pond out there called lake Michigan. I loved teaching and by 1975 I was training PADI instructors. I have operated stores in Illinois, Michigan, Georgia, and Florida. About 15 years I earned the PADI Platinum Course Director award and am proud to say I still maintain that status. Teaching others to love diving like I do and to make a living from it is the best job out there. Today, I still teach and have a blast doing it.

One of the things that keeps me going is all the instructors I teach and all the different classes. I can be doing PADI Instructor course one day, then COR training, and then a photo class. So I am always doing something different.

I hope to dive with you soon.

Chuck Gatti

Master Instructor

I started Diving in 1999 with my first trip to San Carlos, MX. Diving with the sea lions instantly got me hooked if I have not come up for air since.

Shortly after that, my wife and oldest son got certified, and in 2002 when PADI dropped the age to 10, my youngest was one of the first 10 yr old to be certified in AZ. I became a dive professional in 2004 and have certified close to 400 students. I have a “dive club called the SCUBA Mafia,” and we go down to Cozumel about 5X/year, so come along for some amazing dive trips.

“We dive not to escape life, but life not to escape us.”

Dan Martin

Master Instructor

I’ve always been a water dog, even growing up in Wyoming.  When I had the chance to dive in the Pacific Northwest I jumped in with both feet and got certified in 1980 in the cold waters of Puget Sound.  A few years later I learned there was diving in water where you did not need wet/dry suits and 20 lbs of lead, the visibility was nearly unlimited and the life varied and colorful.

In the early 90’s I changed my vacation into my vocation by becoming an instructor and began working on Aggressor Live-Aboards worldwide.  For the next 20 years I got to spend at least a year in places like the Cayman Islands, Belize, Tahiti, Red Sea and the Maldives.  With so much diving, I have spent over a year of my life underwater. 

My two biggest thrills in diving are reliving my first underwater experiences through students and looking for that perfect underwater photo.  The first keeps me teaching and passing on the knowledge, both of diving and equipment repairs, and bringing more people to the sport I love so much.  The latter is the never-ending quest for perfection that will keep me diving, hopefully for another year of my life underwater.

Come into Salt & Sea Scuba and give me a chance to, as the great YODA says, “Pass on what you have learned”.

Gary Gould

Master Instructor

Growing up on the East coast of New England, being in and around water has been second nature for me. Becoming a SCUBA diver in 1994 was a natural progression for me to further my passion for the ocean, and everything that lives in it. My professional PADI dive career began in 2002 as a Divemaster and continued my dive education to receive my instructor rating in 2006.  Teaching SCUBA allows me to share my passion for the coolest recreational activity ever. Being able to contribute, in part, to opening up a whole new underwater world for others to experience and explore is very fulfilling. My student mantra is …… “if you don’t quit on me, I won’t quit on you”.

Having been to six of the seven continents, SCUBA has been life-changing for my wife and I – bringing us too many corners of the world, introducing us to a vast number of wonderful people and cultures, and giving us the opportunity to become SCUBA Ambassadors for the ocean environment.

Erica Mowrey

Master Instructor

The underwater world has enchanted me for as long as I can remember. Diving for me isn’t just a hobby; it’s a way of life. It’s an adventure and an opportunity to see a world that few others get to experience. It’s therapy when life gets stressful, and I need to reset. Most importantly, it has been an incredible bonding experience with my son. We have been fortunate to travel to many unique places, and scuba diving opened that door for our family.

I’ve been diving for 20+ years, and for me, every dive is still new and exciting. I became an instructor to help more people experience the world that I love so much. Whether you are into history, photography, or animal rescue, scuba diving offers something.

Monica Lostumbo

Open Water Instructor

I have always had a deep love/curiosity for the ocean and wanted to make a career making films focused on marine conservation. After I graduated film school, I went to my first try scuba and it was love at first breath! I initially became a diver so I could start learning how to film underwater and ended up going pro within six months after becoming a certified diver. I worked as a Divemaster for five years before becoming an open water dive instructor.

As an instructor, my favorite part is watching my students dive journey unfold, teaching them good dive habits/skills, and hearing about their adventures/planned adventures. For travel, one of my favorite dive sites has been West Bay in Roatan and I was blown away by the tropical forests, beautiful reef, and all the wildlife.

Finn Selander

Open Water Instructor / Service Tech

I started diving in 1973 when I took a Scuba Certification Course on the Army Base at Ft Rucker, AL. My Diving Grounds was the Panhandle of Florida, Sunken Ships, Underwater Caves and Spearfishing! Living is Exploring an Underwater Wreck. I love Catching Dinner (on 2nd or 3rd Dive) and pairing that with a good drink!

I served in the NAVY as an OT (Ocean Systems Tech – Think Hunt for Red October). stationed on Midway Island…180-foot underwater visibility! And Bermuda (Shipwreck Graveyard with 80–100-foot visibility). In 1989 I went through NAUI
College to become a Dive Instructor…
I now teach for NAUI (National Association of Underwater Inst), RAID (Rebreather Association of International Divers), TDISDI
(Technical Divers International Scuba Divers International) and PADI (Professional Association of Dive Instructors).

My other passion is repairing and maintaining dive equipment. When all is said, “I Love Everything Diving” and Introducing New
Students to A Diving Life……

Elisha Bosley

Open Water Instructor

I’ve wanted to scuba dive since as far back as I can remember, however never got around to it. Finally getting my Open Water Certification in 2014 and diving all around the world since then, I can say that I definitely wish I would’ve started sooner. It adds to any vacation, even cold-water ones! Every dive is new and exciting given that there’s always something new to see and experience each time. Whether it be rare marine life like a frog fish, a ship sunken by a torpedo, the experience of flying in a swift drift dive, or huge sink hole in Belize…every time is a new adventure!

As an instructor my two favorite things are seeing students reach that moment where they realize they’ve got it down and also knowing that by sharing this sport with them all the new experiences they’re going to have later in life because of this sport!

Jeremy Stolee

Open Water Instructor

I received my Open Water Certification in 2014 as I prepped for my wedding and subsequent honeymoon in Roatan, Honduras.  I figured I might as well dive in one of the world’s premier dive locations and going forward would be a once or twice per year diver when a random vacation brought me near enough to the ocean…eight years, hundreds of dives and countless hours of training later would suggest I slightly underestimated how amazing I find life under the sea!  

Come join us for a class or a trip and I promise you’ll get hooked too!

Tristin Litherland

Open Water Instructor

I started diving in 2014. As soon as I started breathing underwater on my first confined dive during my certification, I was hooked. The experience of breathing under water and being able to see in person what the majority of people only see on TV is absolutely amazing! I’ve always loved the ocean and sea life.

I’ve been fortunate enough to dive in Iceland, Ireland, Tahiti, Hawaiʻi, numerous locations in Mexico, Florida and California. I became a SCUBA instructor so I can share my knowledge and experience about diving. Being able to see the excitement on a student’s face when they have the same experience that I have when I’m diving is a great feeling! I’m married with 2 boys. In my spare time I train jiu-jitsu.

Jason MacKenzie

IDC Staff Instructor

When I was 16 my step-dad, who is also a diver, took me snorkeling. It was at that time I knew I wanted to go deeper. It took me 25 years to take the giant stride into the underwater world. I began diving in 2017, and from my first certification I was hooked. Within the next 30 days I moved onto an Advanced certification, and continued on through the ranks to obtain Open Water Scuba Instructor in 2021. 

Aside of desiring to travel the world and dive in every location I possibly can, my goal is to share my love and passion for scuba with others. I get a lot of satisfaction by teaching others to dive, and helping others accomplish their goals. Seeing the smiles and excitement on a student’s face when they get their first certification is exciting for me as well….it reminds me why I love scuba. In my other life I’m a paramedic of almost 25 years. Come on in and say hi, would be glad to help you dive into the world of scuba.

Bruce Kessman


In 2004, I became a certified open water diver on the island of St. Lucia and have wanted to keep exploring underwater ever since. Over the years, I have had some incredible diving experiences. Diving with the giant manta rays in Hawaii ranks at the top of those experiences.

Early in my dive career, I was fortunate enough to have my dad as an instructor and mentor. One of my proudest moments as an instructor thus far was being a part of my son’s junior open water certification alongside my dad.

Being able to share my SCUBA experience and knowledge has been very rewarding. I enjoy being a part of the journey from watching a student take their first breathes underwater to becoming a confident certified diver.

Ashley Jackowski

Dive Master Candidate

I first gave scuba diving a shot in 2016 when Tom Horn (my step-dad) asked if I wanted to attend a Discover Scuba Diving class with him here in Phoenix.

My first thought was, “What? Scuba diving in the desert?! Where would we even go?” Despite my doubts, I followed through with the class because *why not* and just like that, I was head over heals in love with it. I received my Open Water Certification shortly after and the rest has been history.

It’s taken years, lots of Refreshers and too many hours on PADI’s e-Learning but I’m finally on the way to becoming a professional diver. Divemasters Certification, here I come!
