I am a dedicated teacher and a Wakonse Teaching Fellow. Dr. Dryden and I team up to present the Clinical Veterinary Parasitology Course in the fall of the 2nd year of the professional veterinary curriculum. I am the course co-ordinator for Integration III also taught in the fall of the second year curriculum. The Parasitolgy review session for 4th year students rolls around every 3 weeks were we present current parasitology information including new parasiticides and hot topics.


I am the Supervisor for the Diagnostic Parasitology Laboratory for the KDVDL and the Veterinary Health Center. I serve as Student club advisor for both the Canine Club and Small Ruminant Practitioners.  I have made presentations at the College Veterinary Technicians Conference and the June Conference for Veterinarians as well as at National meetings including AAVP, NAVC and WVC. I am on the American Heartworm Society Board of Directors.

As a personal service project I have been involved with the KSDS, Inc. Puppy in Training Program since June 10, 2003. Our first pup Maize, came to KSUCVM as a 10 week old female yellow Labrador puppy, in June of 2003. She stayed by my side until the spring of 2005. She attended classes and seminars throughout KSUCVM and could be found snoozing under my desk in Coles 333. Maize put smiles on the faces of faculty, students and staff daily. She was available for post exam hugs at all times. She was returned to KSDS early in the spring of 2005 for further evaluation and training. She passed the rigorous health exam and went on to be a partner for a disabled person. She will always carry part of my heart and will be missed by all of her friends here at the college. Since then Asheni, Tinsel, Calais, Barstow and Champagne have followed in her paw prints bringing joy and humor into the lives of students and faculty alike.


I am a 1971 KSUCVM graduate who practiced small animal medicine in Virginia for 23 years before returning to earn my PhD in Insecticide Resistance in Fleas. This insecticide resistance research continues today. Current research projects still evolve around fleas but now also include ticks, Giardia spp. and Tritrichomonas foetus in cats and bulls
