The Philadelphia Herpetological Society
(PHS) is the oldest, continually operated reptile
group in North America
. It was founded by Roger Conant (herpetologist)
and a group of like-minded herpetologists
in 1952. The current president is Mark Miller.
PHS has published the Bulletin and occasional newsletters throughout its history.
They seem to meet infrequently at present but operate a reptile rescue for animals in the Philadelphia metro area, and a wildlife conservation area in Southern New Jersey.
