Instructors & Instructional Staff

DIT Instructors & Faculty

 Mike “Doc” Redeen, Director of Training, SCPO/E-8/USN/RET

Originally from Missoula, Montana, “Doc” graduated from the Naval Diving and Salvage Training Center (NDSTC) in Panama City, Florida and spent 26 years active duty in the U.S. Navy. His Naval career included experience as a Diving Independent Duty Corpsman and took him all over the Western Pacific, Philippines, Florida, Hawaii, Connecticut, Guam and Virginia. To expand his skills and knowledge base, Doc has completed the Undersea & Hyperbaric Medical Society’s (UHMS) two-week, extensive Physician’s Training in Diving Medicine course in June 2012 at the National Oceanic and Atmospheric Administration (NOAA) campus in Seattle.

As an Instructor, Mike enjoys passing on his knowledge and experience to the next generation.  At DIT, Doc has instructed in Physics, Medicine, Chamber, Intro to Lightweight, HeO2, Deep Dives, Midterms and Finals. Doc recommends that future divers take initiative, have a good attitude, be willing to learn and practice using their “two eyes, two ears, and one mouth” to be successful in the industry.

Advice to students
“Never give up; take it one day at a time.”

Michael Kleinfelder, Assistant Director of Training

Mike is a DIT graduate who has been an instructor at the school since 2007. In his diving career, Mike has worked with inland companies in Seattle, San Francisco, and Louisiana. Most recently, Mike has trained DIT students with courses on the M/V Response for Sur-D O2 Deep Dives and the HEO2 Mixed Gas Theory/Finals Week

Advice for DIT Students and Alumni
“Remember, in the water, you’re working in an environment that we as man, are not meant to be in. Place safety as your highest concern not only for yourself, but also for all those you work with. Share your knowledge and experience. Strive to keep your work ethic high and work as a team.”

Randy Busby, DIT Instructor—Deep Dives and Finals, PO3/E-4/USN

Randy is a 1998 graduate of DIT. He served in the Navy as a Boatswains Mate 3rd class and was a rescue swimmer attached to the Inshore/Underwater Warfare group in the Pacific NW. His diving career began with a year in the Gulf of Mexico, then five years as an inland diver conducting repairs and inspections on dams, water towers and piers. Randy spent seven years with Global Diving & Salvage in the Gulf working on P & A, salvage platforms and hurricane work.

Randy became an instructor at DIT and enjoys students’ enthusiasm. His favorite part of instructing is seeing students’ faces when they’ve accomplished a task and realize the project was not so bad, or that it was hard, but they got it done and can be proud of themselves. Randy thinks that the hardest challenge for new graduates entering the dive industry is the learning curve for the rate or speed of how work gets done in the industry; new divers need to learn quickly 100% of the time to move ahead. Randy teaches DIT students the need to put in their time starting in the industry, knowing that they don’t get stuff handed to them as young divers.

Advice to Divers
“Ears open, mouth shut. Be a sponge; soak up every bit of knowledge. Also, look at the divers ahead of you. Find a diver you respect and emulate him; do what he does, find out what gear he wears and wear that, follow his example and become like him.”

 Steve Coleman, DIT Instructor—Deep Dives, First Aid/CPR/O2/AED, CPO/E-7/USN/RET

SteveColemanSteve L. Coleman was born and raised in Beaverton, Oregon and attended Beaverton High School. After graduation in 1990, he joined the U.S. Navy as Hospital Corpsman in March of 1991.  Steve worked with the Marine Corps for 12 years growing his background in hospital-based medicine and psychiatric care. He later attended the Naval Diving and Salvage Training Center in May of 2003, earning class Honor Graduate. In total, Steve served 24 years in the U.S. Navy as a Hospital Corpsman achieving the rank of Chief Petty Officer. He was a Qualified Master Training Specialist at two commands. He served 12 years as a Diving Medical Technician earning a Hyperbaric Oxygen Technician Certification and a Bachelors’ Degree in Health Care Management.

Throughout his military career, Steve was a Deep Sea Independent Duty Corpsman (IDC) assigned to MDSU-TWO in Virginia Beach, Virginia. He served at three Explosive Ordnance Disposal commands providing medical coverage during high risk operations involving MK-16/SCUBA diving, parachute and demolition operations. His deployments included Anti-Terrorism Force Protection during 2008-2009 and a 2010 deployment on the USNS Grapple with a mission of providing salvage work in the country of Albania along with instruction and education of diving and salvage to host nations. Steve said his most memorable moment was responding to the 2010 Haiti Earthquake in Operation Unified Response, “where I was able to treat a local commercial diver suffering from DCS type II. As the Senior Diving Medical Technician, I led and oversaw the successful treatments resulting in the diver’s ability to walk unassisted following multiple US Navy [Treatment Table] TT-6’s.”

Steve joined us at Divers Institute of Technology in August 2015 to instruct in the HazMat I/HAZWOPER and First Aid/ CPR/ AED modules. He’s already adding his skills and resources to enhance our students’ training in both modules.

My advice to new divers is:
“Look to the past as much as you look at the present. Lessons learned have come from those who put their blood, sweat and tears into diving, some which we have learned came at the cost of losing our brothers and sisters. As divers today it is important to do what is necessary to not let mistakes repeat themselves and listen to those who have “been there and dun it” and “Got the tee-shirt”.”

Jason Conover, DIT Instructor –Lightweight/ Rigging, Physics/Medicine

Jason was born in Seattle and is a Seattle/Everett, WA native who attended DIT as a member of the 110-08 class. After he graduated, Jason started his diving career working offshore in the Gulf of Mexico with Epic Divers & Marine. He later expanded into diving internationally, working with Technip and Aqueos, as well as doing some inland diving with Associated Underwater Services (AUS).

Some of Jason’s favorite dive work has included the demolition of decommissioned oil platforms in the Gulf of Mexico using hydraulic diamond wire saws and explosives, as well as installing spool pieces in saturation for new pipeline construction.

His professional background includes a diverse welding background using all processes but focusing on TIG welding on aerospace parts, hydroplane propellers, and basically anything except regular steel (titanium, stainless, brass, aluminum, etc.).  He’s also been a Nutritional consultant and Level 1 CrossFit Trainer and Coach at CrossFit Advantage, with an emphasis on CrossFit Weightlifting and Gymnastics.  Jason returned to join the DIT Instructor Staff in September 2016.

Advice for new divers:  “Keep your head down and work hard, and work to develop a keen eye for details. Keep your safety and your coworkers’ safety a top priority.”

Jake Dow, DIT Instructor–Offshore, HazMat

A Pacific NW native, Jake was born and raised in Centralia, Washington although his offshore dive work has taken him to places like Nigeria, Mexico, and the Bahamas.  Jake graduated from DIT in 2006 and also was trained as a Union Journeyman Carpenter, working both for Kuney Construction and then later Cal Dive International.  In commercial diving, Jake’s favorite work is heavy, big salvage work like removing old platforms with 800- to 1000-ton lifts because the process is big and the work is exciting.  As a diver, Jake valued his dive team  like family–especially a particular core group of guys who dove together, bailed each other out, and “became men together.”

Advice to New Divers
“Set clear short term and long term goals.  Focus and do your best to obtain them!  In the dive world you have to have “grit.”  Work hard!”

Sean Day, DIT Instructor—SCUBA, Inland

Advice to New Divers
Commercial diving is a challenging industry that will refine you. It will bring the best out of you if you are willing to face the challenge.”

Josh Oxley, DIT Instructor—Welding, Burning

Southern California native Josh graduated from DIT in 2005 and started his career offshore working all over Mexico, Florida, and the Gulf of Mexico on various dive jobs. Josh’s work included installation, removal, inspection and repair of offshore oil and gas pipelines and platforms. Career skills that Josh has gained from the diving industry include problem solving, effectively dealing with large companies and learning how to work alone on the bottom. Two qualities Josh recommends for divers who want to be successful in the industry are ability to work with people of various personality types and a good work ethic.

“Be aware that choosing diving as a career is a big lifestyle change and a big investment in yourself.”

Advice to Divers
“Make sure you have a strong family and a solid plan for finances. Divers’ lives are that of the nomad, very similar to the military. Divers have to be wise about money matters, and have a deep larder for slow work periods. It’s a great lifestyle, with great pay and benefits, but there are slow times. It takes time and you have to pay your ‘dues’ to work your way up in the industry.”

Jeff Stiefel, DIT Instructor— Hydraulics, Salvage, NDT

Born at Fort Carson in Colorado Springs, Colorado, Jeff was an Army brat who grew up all around the country. As a graduate of the 112-05 class at DIT, he worked for U.S. Underwater Services as a Diver and for Central States Underwater in Houston, Texas as a Supervisor and Project Manager. His specialty, and favorite dive work, is flanging up spool pieces. Jeff enjoys giving back as a DIT Instructor.

“Learn all you can, as much as you can to your skill level, to become an asset to the commercial diving industry.”

Joel Duker, DIT Instructor – Offshore, HAZMAT

Joel is a Seattle native born in Redmond, WA and graduate of Nathan Hale High School.  After graduating dive school at DIT in Class 110-06, he began his commercial diving career in the Gulf of Mexico with a year at Tiburon divers. Joel hired on and spent 8 more years in the Offshore sector with industry giant Cal Dive International until they closed in 2016.  Bringing his robust offshore experience to the next generation, Joel joined longtime friend and coworker Jake Dow at DIT in April 2017 as part of the Offshore and HazMat instructor team.

Advice to students: “Remember it is the little things that we do in our industry that make a big difference! No one was born knowing how to do any of this, so remember to work within your skill level and absorb as much as you can every day!

Daniel Matthes, DIT Instructor, Welding/Burning, NDT, SCUBA, Inland

Daniel was born and raised in Tome, NM, a small farm town of less than 2000 people nestled along the Rio Grande Valley on the foothills of the Manzano Mountains. He came to DIT right after high school and served as DIT class president for 106-06, later doing adding General Studies at Lonestar College in Houston and General Studies/Lab Assistant  at the University of New Mexico.  (Ask Daniel about his UNM Paper: Identification of Skunk Species Submitted for Rabies Testing in the Desert Southwest.)

Early in Daniel’s commercial diving career, he worked deep water platform support with Epic Divers and Marine, eventually moving over to the shallow water pipeline support sector with G&G Marine. The majority of his dives were conducted in the blackout conditions of the “mud hole” part of the Gulf. The work is very similar to that of an offshore diver, however, crews operate closer to that of the Inland sector, so Daniel’s experience shows how interconnected these sides of the industry can be. He began supervising full time in mid-2013 before making the transition to Seattle to join the DIT family in August 2017, where he’s since revamped the Inland module and is challenging students daily in their real-world Inland dive site skills.
