Hi, Welcome to our site! 

This site has been created by Donna and Nick Barrett, PADI Instructors since 2009 and 2010 and obsessed divers since 2005. The site is dedicated to our passion for diving and our desire to share this with all who will listen! If you, or someone you know is interested in learning to Scuba dive, or just want to try it to see if you like it, drop us a note at washdclady@mac.com or washdcguy@mac.com with the subject line “learn to scuba dive”.
