Mike is a member of the Advance Diver Magazine Exploration team and a participant in the US Deep Caving Team. Recently Mike dicovered a Myan vase that dates back 1300 years while exploring and mapping cenotes (caves) in the Yucatan peninsula area. In 2010, Mike helped with the J2 system in southern Mexico that is 1200 meters deep which took 2 days of caving just to get down to the water. In 2011, Mike and the deep caving teem mapped an underground river system in Puerto Rico that totaled over 23 kilometers in length making it the world's longest underground river. Some of the area surveyed had never been seen by human eyes before.

Mike’s desire for diving and reaching areas unseen has led him to custom build many of his own products; several of which that were not available at the time. Together with Hollis, Mike has been influential in designing several products. Mike is also responsible for the development of the GEM gas extender Rebreather.
