Jeri specializes in educating all ages about the Earth, especially concerning local topics.
His love for geology is reflected in his teachings, as he passes his knowledge on to others to learn and enjoy. Either one of his established programs or a program to be custom-made for a class, organization or individuals is a great idea for a program or special presentation. Jones Geological Services has the below listed programs:

Jeri is a trained Facilitator for the Out of the Rock program in Pennsylvania and offers workshops for teachers through the York County Parks once each year. 

Classroom or Meeting Setting:

1. General minerals, fossils and rocks and how do we use them.
