Our Team

Tim Jewell


Tim Jewell received his dive training in the military in the early 70's. After leaving the military Mr. Jewell chose to participate in the booming King Crab fishery as a captain. Due to the lack of divers in the remote fishing grounds he used his training to perform a variety of ships husbandry jobs, prop work, net removal, and grounded vessel reports. Enviro-Tech Diving was formed after Mr. Jewell was approached by the seafood processing industry to deal with new requirements dealing with water quality standards in Alaska. Enviro-Tech Diving, Inc. worked with industry stakeholders, ADEC, and EPA to implement a standard for surveying seafood waste on the seafloor. These meetings eventually helped craft the first NPDES General Permit for Seafood Processors. Over the next 30 years, Tim grew his company into a diverse dive company doing marine construction, salvage, and environmental work from California to the Arctic Ocean
