John Monson

Independent Advanced Open Water Instructor

I am an SSI Advanced Open Water Instructor and a Level 9 diver with over 43 years worth of diving experience to share with you. I enjoy seeing entry-level divers conquer new skills, existing divers explore new experiences, and all divers challenged to expand their knowledge both this great sport. My most memorable recreational dive was getting my picture taken on the screw of the Spiegel Grove, which is now buried in the sand after a hurricane righted the ship. My regular job is in the IT field and sometimes involves communication towers. My other hobbies include hiking mountain trails in Colorado, traveling, and working with Amateur radio. Scuba diving enables us to expand our friendships, share common experiences, and learn from each other.

Michael Dugan

Independent Scuba Instructor

I started diving in the early 80s, and in those few years I’ve learned that the phrase “let’s get in the water” is something to live by. Bubble therapy is highly underrated. In my life I’ve been blessed with great health, great friends, a wonderful relationship with the water, and the ability to share my passion with others. My dive career started in the Navy in 1985 aboard fast attack submarines and my goal at Diventures is to show “my world” to others by teaching and showing my passion to others and giving each student the opportunity to make it their world, too.
