Roger M - Volunteer Naturalist

I got hooked on being in nature as a kid wandering the palmetto scrub and backwaters of west coast Florida in search of critters and fossils. Though a third-generation geologist, I’ve never earned a dime with my geology degree. For 3 years as a Peace Corps Volunteer in Ghana, I taught secondary school geology, chemistry, math, and general science. A second degree in graphic design led to a career in technical and scientific illustration. I have been volunteering as a naturalist since 1976.
