Michelle Johnson, Office Manager
Michelle has been our office manager since 2008 and comes to us with a diverse and unique background. She is a practicing nurse with expertise in acute care, skilled nursing, home health and Hospice care. She has also worked with developmentally disabled children and adults teaching them daily living skills. Michelle also loves animals; she has several dogs and cats, but her background suggests that she has a particular fondness for birds. In addition to her guineas, she has bred and hand-raised parrots for twenty-six years! It started as a hobby and turned into a successful business. However, raising parrots requires daily care and the desire for a little free time compelled her to reduce her parrot flock to two chatty Amazon parrots. Her hobbies include ceramics, plants, gardening, and bonsai.
Patrick D. Lorch, Senior Research Biologist
Pat has an Undergrad degree in Biology from Notre Dame, a Masters in Zoology from University of Maryland, and a PhD. in Behavioral Ecology from University of Toronto, focusing on evolution of insect mating behavior, sexual selection, and life history evolution.
