Under Water Works

Explore the PNW's kelp forests or plan your next international adventure with this community-focused dive shop.

Under Water Works is a dive shop and training center located in Tigard, Oregon. Founded in 1975 by Hilde Frey and purchased by Gretchen Jones in 2015, the business focuses on providing scuba and freediving education to the local community. The team of PADI instructors offers courses ranging from basic Open Water certification to professional-level programs like Divemaster. The shop serves as a hub for Pacific Northwest diving enthusiasts, offering equipment sales, rentals, and in-house servicing including regulator overhauls and tank fills. While they do not operate their own dive boats or liveaboards, the business organizes international dive travel packages to destinations such as the Dominican Republic and Bali. In addition to formal certification courses, Under Water Works hosts monthly free community fun dives for certified divers of all skill levels. These local excursions allow participants to explore PNW underwater environments featuring kelp forests and marine life like giant Pacific octopus.
