When Pat isn't overseeing the visitor experience at the Edelman Fossil Park & Museum in Mantua, NJ or running the annual Visitor Experience Conference, you can find him all over the Delaware Valley looking for fun things to do with Tri-State Nerdery or all around the country assisting cultural and tourist attractions with their training. So whether you are looking for an unforgettable wedding day, training on how to be a better leader, a flawlessly planned and executed event, or even just something nerdy to do near you, you have come to the right place.
