Club Leadership

Susan Posey

Club Chair

Susan Posey began caving in 1990, while living in West Virginia. Her first grotto was/is the Monongahela Grotto, but she has been a member of PSC since the mid-90’s, moving to the Washington DC Metro area in 2001. Over the years she has been active in Monongahela Grotto’s Tucker County WV survey, the Shaver’s Mountain WV survey, the Hellhole Cave survey and the Germany Valley Karst Survey. She is still active in the GVKS and especially enjoys cave digging.

Paul Gillis became fascinated with caves when he was a teenager living in Kentucky, but he never met up with any real cavers until he was in his mid-twenties, living in Pennsylvania. In 1982 he moved to Virginia and joined PSC, as well as D.C. Grotto and the NSS. He enjoyed more than 20 years of active caving with these new friends, exploring, surveying and taking photos of the underground. Nowadays he considers himself an “armchair caver,” doing his bit to keep PSC going as an active club and enjoying the opportunity to hang out with other

cavers.

Art Latterner

Executive Director

Art Latterner is a great guy! But it’s been a long time since he last took his daughter caving.

Edgard Bertaut

Director, Membership Chair

Edgard Bertaut has been actively caving since the late 1990s and joined PSC in 2004.  He was drawn into caving first by tourist trips and then by the Gangsta Mappers Cassell Cave project.  Since that time, most of his caving has been survey trips into Memorial Day Cave, along with the occasional tourist trip.  From short trips with beginners to serious project caving, it is all caving and it is all fun.
