DIT Instructors & Faculty

Daniel Matthes, Director of Training

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.

Quotes to live by:

Failure is only postponed success as long as courage ‘coaches’ ambition. The habit of persistence is the habit of victory.” – Herbert Kaufman

Discipline is based on pride, on meticulous attention to details, and on mutual respect and confidence. Discipline must be a habit so ingrained that it is stronger than the excitement of the goal or the fear of failure.” – Gary R. Blair

I’ve used the skills taught to me by the great instructors at DIT on a daily basis. I continually run into DIT graduates out in the field, and they’re always hardworking, professional, and very well trained. After all these years, I still love what I do! I always knew I wanted to see the world, and what I learned at DIT provided me with the opportunity.

Pete is currently the Course Director of the Diving Medic program at DIT, filling these highly demanded positions in the undersea industry.

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.”

Britt Coates, DIT Instructor – Offshore, HazMat, Lightweight, Rigging

Britt was born in Wenatchee, WA and has spent two thirds of his life living in Washington State. A graduate of the 106-08 DIT class, Britt spent a year and a half after school working in the Gulf of Mexico with Global Diving & Salvage on plug and abandon (P & A) work of killing oil and gas wells. He continued his diverse dive experience in more than a year with Ballard Diving & Salvage on dive jobs doing dam work and supervising a couple high profile HazMat jobs. In some memorable salvage diving, Britt worked on jobs in which the ship being salvaged was disassembled underwater. Some of Britt’s other dive work thus far has taken him to Florida with Subsea Global Solutions (Miami Divers) where he worked in ships husbandry, inspections, and repairs on vessels including Royal Caribbean’s Allure of the Seas, the largest passenger vessel ever built. In Florida, Britt also worked for Underwater Engineering Services (UESI) in underwater construction and conducted bridge inspections & repairs, power plant inspections, and nuclear power plant maintenance. Britt has traveled to the Bering Sea for a 6-month stint of flange up projects and inspection work as well.

In June 2013, Britt spent 5 weeks supervising a dive team at Palmer Station, Antarctica, one of only 3 U.S. Antarctic research facilities in the Antarctic Circle, and 4 days journey by sea off the southernmost tip of Chile. Palmer Station hosts employees from Lockheed Martin and researchers from the National Science Foundation (NSF). Amidst waves filled with floating iceberg chunks, the dive team built a new boat launch to accommodate larger vessels that will expand the radius from 2 miles to 25 miles’ capacity for collecting research samples.

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.”

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!”

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.”

Nick Robinson, DIT Instructor, Lightweight and Rigging

Nick RobinsonOriginally from Chicago, Illinois, Nick was a Graduate of DIT and has been an Instructor with us since September 2019. In addition to graduating from the Divers Institute he received his Degree in Education from Northern Illinois. He has years of Salvage and Nuclear diving experience all from the mid-west region. 

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.”

Sean Day, DIT Instructor—SCUBA, Inland, Lightweight


Sean grew up in a military family and was born in Landstuhl, Germany and was raised in Florida, New York, and Washington. Sean was in the Navy as a Weapons Division Diver attached to the submarine USS Providence before attending DIT in 2014.
