I have been an avid amateur naturalist since early childhood growing up on a small farm in Perry County PA. I have traveled all over the USA and extensively internationally for work and pleasure. I have my PhD in Environmental Engineering. My career before retiring in 2008 was as an industrial hygienist, which is recognition, evaluation and control of human health hazards primarily occupational but also general public risks from chemicals, radiation, noise, microbiological agents.

I am married 45 years this year with two children and two grandchildren. Our grandchildren now share our love of nature
