Raptor Biologist. I grew up in Florence, Oregon on the Oregon coast, graduated from
Willamette University with a B.S. in Computer Science and Mathematics. I have since lived
in Idaho for 27 years. I worked at Hewlett-Packard for 21 years before quitting to pursue
a new direction in Biology. I graduated with a BS in Biology with an emphasis in Ecology
from Boise State University in May 2010 and graduated with an MS in Raptor Biology and a
graduate certificate in Geographical Information Analysis in May 2013. I now work at the
Intermountain Bird Observatory as a Research Biologist.
