J.G. has been living in the Ithaca, NY,, region for the past few years.
"Hertzler, 63, known professionally as J.G. Hertzler, moved to the Finger Lakes area several years ago after coming to the Northeast from California. He performed in Rochester at Geva Theatre and then came to Cornell University in Ithaca as a visiting professor in acting."
He has been there since about 2008, I believe.
