Alex Blevins

Alex Blevins is an IANTD, TDI, SDI and PADI MSDT instructor who just simply loves to dive. He lives for it. You will often find him in a cave somewhere on his choptima running lines or scootering along. When not caving, you can find him perusing tide tables to see if he can squeeze in a quick freediving or spearfishing trip.

Prior to opening Adventure Outfitters with his mom, Anna in 2014, Alex worked with USAA and the United States Social Security Administration. Alex graduated from the University of Missouri in 2009 with a bachelor’s degree in Business Administration and a minor in Mathematics. He is married to Jenny, who is also his life-long dive partner and cave buddy. They have two young daughters together who love the water.

Alex is Adventure Outfitters’ service technician and an equipment guru. He has a passion for rebuilding and collecting regulators. He enjoys the challenge of fixing and repairing them and the craftsmanship of their design. He also has a wide knowledge of technical diving and the gear that goes with these specialty activities. Ask him about rebreathers, sidemount, doubles or trimix diving any day!

Alex also loves teaching, especially when he is working with recreational divers who want to become more confident divers and pursue more advanced courses. Alex also teaches many specialty courses including Intro to Tech, Intro to Cave, Full Cave, Cavern, CCR / Closed Circuit Rebreather - O2ptima, Trimix, Equipment Repair, Enriched Air / Nitrox, Equipment Specialist, Wreck Diver, freediver or Sidemount but probably his favorite activity, is teaching others to cave or cavern dive, hunt, spear and fillet their fish! Alex is always learning and growing as a diver and instructor. He is currently pursuing his CCR Trimix Instructor designation.

Jenny Blevins

Jenny was certified in 2011 and has always loved the water. Growing up in Missouri, she often went to the Lake of the Ozarks to swim, snorkel, boat and fish. Since getting certified, she has continued on to become a SDI and PADI instructor. She enjoys cave diving on her O2ptima with her husband, Alex. Jenny is the organizer, manager and scheduler of sorts. While maintaining a passion for the sport, she also helps with scheduling, managing the retail store and keeps classes and adventures going.

What you like most about diving/what type of diving you like to do:

Once we moved to Florida, I fell in love with the Florida springs, they are truly a hidden gem in Florida, and did my Cavern. I then continued on to get my full Cave certification and CCR certification. When I am in the Florida caves, I am the most relaxed I have ever been. I also really enjoy spearfishing, freediving, fossil diving, tech diving and photography.

What do you do outside of diving – what do you do for a living:

I have had lots of passions, including dance and musical theater. Before I started working at Adventure Outfitters full time, I was a Marketing and PR Manager for a national commercial real estate firm.

Outside of diving, I really enjoy hanging out with my husband, Alex, our pups, BMO and Frankie and our baby girls, Athena and Freya who are the loves of my life!

What is your next dive class and/or your diving goal?: 

I am currently working my freediving instructor and focusing on more technical diving courses. Eventually, I would love to share my love of cave diving with others and that the caves are more than dangerous, dark tunnels but beautiful, windows into Florida's past!

“COZMO” Isaac Neiger

Cozmo was certified in 1997 at the same shop that his parents certified 20 years prior in Northern California.  Fell in love with the cold waters of the Monterey CA area so much so he would dive the ice cold kelp beds 200 times a year in the early years. Almost from the beginning Cozmo fell down the rabbit hole of Tech diving the then crazy dark side of scuba “I had to, they have cookies"

 In 2000 Cozmo opened California Underwater Explorers to share his love for tech diving and in 2001 got hypnotized by the prospect of exploring underwater caves and took off to Florida to get trained.  In 2004 life got in the way and vacationed New Jersey for about 15 years doing a few trips here and there to the caves in Florida.  Cozmo then landed in Florida for good and been cave diving since.  Cozmo became a IANTD instructor to help share his love of diving to others and in the first quarter of 2022 opened his secound shop in Riverview Florida.

What I like most about diving/what type of diving you like?

I love the zen I get while cave diving and exploring different cave systems.  I also try to use my O2ptima rebreather as much as posable as it gives me all kinds of time underwater and also able interact with the wild life that does not happen with open circuit.

What do you do outside of diving 

I have many things I like to do outside of diving.  I have been guilty of Kayaking, Sailing, Crew chief of a Big Block Modified race team, camping, a little hunting and riding my motorcycle. 

What is your next dive class and/or diving goal

I have plans to continue my instructor ratings like cavern, rebreather and exploration Trimix.  I also would love to dive the Britannic, and cave systems in Europe and Mexico.  When Cozmo is not in the shop or teaching he will be found spending hours cave diving.

Anna Blevins

Anna is the heart of Adventure Outfitters. She has an unsurpassed passion for teaching people how to dive safely and to enjoy whatever the underwater realm has to offer. She takes great pride in ensuring that each dive student feels fully confident and has mastered every skill. She doesn't hurry her students and will take as much time as needed to ensure that they will be a strong, confident, safe and happy diver.

“When I started diving, I was a nervous Nellie and that is what encouraged me to take additional dive classes. Questions such as: Why is enriched air better? What’s that “random” number on my dive computer for? Why can’t I properly find the boat and have to swim back to it? were finally answered! As I continued taking classes I began to appreciate everything a little more and gained a better understanding of dive theory – why things work the way they work underwater.  Most importantly, I understand what the nervous diver is going through and the best part is, the more training you do, the better diver you become. I make sure that classes are only as large as the individual diver can handle. We don’t do cattle calls and we always make sure that safety is top-of-mind.”

In 2014, Anna, along with her son Alex, took leadership of Adventure Outfitters. Anna is focused on bringing customer service to the forefront of the Tampa dive center along with a variety of activities, trips and speaking events for divers to enjoy. She is the champion of the dive center's city-wide dive initiative to help clean up our marine environments working with Project AWARE’s Dive Against Debris and local organization Keep Tampa Bay Beautiful.

Anna currently is a PADI Instructor Development Course / IDC Staff Instructor and Emergency First Responder / EFR Instructor Trainer. She is full-cave certified and likes to teach a variety of courses including divemaster, cavern, advanced, master diver, snorkeling, open water and many more specialties.

Anna became certified in 2004 along with her two sons and husband in order to dive while taking a trip to Puerto Rico. She is an Army veteran and served as a litigation paralegal for several years.

Robert Blevins

Robert is a certified TDI, SDI and PADI dive instructor for Adventure Outfitters. You can often find him diving with his son Alex in a cave or up and down the escalator in the USS Oriskany.

Robert is a retired U.S. Army Reserve veteran participating in Operation Desert Shield/Storm, Operation Enduring Freedom, and Operation Iraqi Freedom. Robert has been married to Anna since 1984 and is a graduate of Colorado State University and Regis University in Denver. He enjoys all aspects of diving including recreational diving, spearfishing, cave, and deep trimix diving. He also is a Handicapped Suba Association (HSA) instructor, able to train  disabled divers as well as their buddies. Robert will gladly share any aspect of diving and dive training with any interested student.

“Since my early years in Fort Lauderdale I’ve always wanted to dive and spent time in the ocean swimming and snorkeling. We started out in the muddy lakes of Missouri and northern Arkansas, but since then, I have enthusiastically pursued all types of diving and underwater recreation. I enjoy diving in perfect, gin-clear waters of a Florida spring or on a reef in the Caribbean as much as I do in poor visibility of a winter shore dive in the Gulf or exploring a silted wreck.”

Robert loves diving deep, unexplored wrecks and is currently pursuing his CCR Instructor Certification.

Scott Grizzard

Scott started diving with his dad at 12 years old, but was, “a casual resort diver” until one day they were rained out, and he went diving in a cavern.  Scott was hooked forever.

Scott has been a PADI instructor since 2013, PADI IDC Staff Instructor since 2014, and he loves to teach Open Water, Advanced, Peak Performance Buoyancy, Deep, Navigation, Cavern, Divemaster, and Sidemount.  In his surface intervals, Scott is a mathematician and economist, and he teaches dive physics with a smile.  (No divemaster candidate of his has ever failed the physics test.)  

Scott claims he can teach anyone to back kick: “It is just a matter of getting your trim right.”

Scott loves caves (especially shallow, less-hassle Mexican caves), and ultimately wants to teach cave diving.  Just don’t ask him to go on a boat… he hates boats but loves the ocean.

Ed Nester


How long you have been diving: 

I taught Red Cross swimming from 1992 to 1997 at the Princeton YWCA. Going into the Army my love for the water was put on hold for a few years. I got into diving in 2015 and have not stopped.

I started with a SCUBA class from the Vicenza Italy ODR shop for open water, then the Advanced Open Water.  I worked as a Training Assistant through that shop, diving in Italy and Croatia.  I decided to continue my diving education after attending cleanup dives sponsored by Adventure Outfitters.

What is your next dive class and/or your diving goal?: 

The family atmosphere, professionalism and best quality of teaching is what made me want to become a divemaster.  I enjoy all sorts of diving and try to ensure the people diving with me have a great experience.  I also have a love of kayaking, snorkeling, and gardening.  I’m looking forward to becoming a PADI SCUBA Instructor this year.

Rosalind Gatling

Rosalind Gatling is a certified Instructor for DAN CPR, AED Adult/Child/Infant, Swimming Water Safety and Master Diver, Dive Master 

"I began teaching swim lessons to preschoolers and preteens to adults, or just anyone who has the drive and passion to want to perfect their breathing and stroke technique for 3 years now.

I am a natural born teacher; I also worked with children for the past 5 years as an Instructor/Coach. I have taught softball, tumbling.

I love teaching swimming. The joy I experience when I see students grow, and further enhance their abilities. I feel that nothing is greater than to see a person go from the fear of drowning to know that they have learned and mastered drowning prevention."

Branden Weber

Diving Experience: I started my scuba diving journey in 2015, diving into the waters of Square Lake, Minnesota. The adventure began as a family vacation activity and quickly grew into a passion. Ever since, I've been continuously exploring the depths and getting the most of my certifications. I am currently a PADI and SDI Open Water Instructor who enjoys helping young adults like themselves Raise the Dive Flag

Passion for Diving: My diving interests particularly lie in Wreck and Boat Diving. There's something incredibly fascinating about the history that lies underwater, exploring old ships and witnessing the marine ecosystem thriving within them. Each dive is like a journey back in time, offering a unique story and an unforgettable experience. The thrill of discovering these submerged treasures and the peace of underwater exploration is what drives my passion for diving.

Life Beyond Diving: When I'm not diving, I'm helping guide entrepreneurs at The University of Tampa. My role involves guiding young entrepreneurs as they start and scale their businesses.

Diving Goals: Having achieved my PADI Open Water Instructor certification in March 2022, my next aspiration is to broaden the horizons of aspiring divers. There's an indescribable joy in introducing students to the underwater world and helping them achieve their diving certifications. I am committed to spreading this passion, fostering a new wave of divers who can appreciate and explore the wonders that lie beneath the seas
