Our deepest hope is that these images will inspire you to think about the plight of planet Earth.

We have taken them in the most spectacular habitats on the planet over the past 30 years. The wildlife is still there, but in many cases it may not be there for long.

Our favorite places are East Africa, Costa Rica, Antarctica, and South Georgia Island. The Coast Redwoods of northern California are not far behind.

Our goal is to provide a portfolio which depicts biology, behavior, and beauty.

Greg is Clinical Associate Professor of Psychiatry at the University of Texas Southwestern Medical School, and Mary Beth has taught elementary school in the Richardson Independent School District. An award of Teacher of the Year was given to Greg at Southwestern Medical School in 2006 by the 4th-year residents in training in psychiatry.

Our presentations at academic centers and in the community are described on the next page.
