  • My NAUI Bio

    I became a certified diver in 1998 and fell so in love with the sport that I continued training and received my instructor certification in late 1999. I crossed over to the NAUI Organization in 2002. By 2004 I received my Full Cave Cert (Still really proud of that one). My biggest passion is North Atlantic Wreck Diving. Exploring all the cool wrecks the ocean has to offer is really pretty awesome. In January 2013 I received my Technical Instructor Certification and can now teach up to Trimix II (Extreme Exposer Diver) (No cave yet but maybe someday). Come diving with me someday and experience some of the best wrecks around whether they be shallow or deep:) Safe Diving and always have fun!!
