Dr. Bob Dahlhausen earned his DVM from The Ohio State University in 1983, MS in 1980, and completed coursework and general exams towards his Ph.D. in 1983. He has practiced avian, exotic, and laboratory animal medicine for the past 41 years. As a researcher, he helped pioneer embryo transfer techniques in exotic animal species including the first successful interspecies embryo transfer of the African Bongo antelope.

He was a research consultant to the Procter & Gamble company where he helped develop on-site protocols for veterinary surgery and assisted in establishment of the company’s Institutional Animal Care and Use Committee (IACUC) program. Dr. Dahlhausen served as a consulting veterinarian to the Department of Laboratory Animal Medicine, University of Cinicinnati College of Medicine, and to the Ethicon Endosurgery Institute, Professional Education Division, where he assisted in surgeon training in endoscopy and endoscopic surgery.

In 1991, Dr. Dahlhausen established Veterinary Molecular Diagnostics (VMD), the first commercial molecular diagnostic laboratory to serve veterinary medicine. In addition to developing assays for select avian and exotic animal diseases, the laboratory developed specific testing for avian Chlamydiosis that is a current standard today. Dr. Dahlhausen is a leading researcher in avian ganglioneuritis, offering the only anti-ganglioside antibody ELISA available for disease diagnosis and having pioneered the use of COX-2 inhibition for the successful treatment of this disease. He has given over 126 presentations and written33 scientific publicationsand for 4 veterinary textbooks.  In 2009, Dr. Dahlhausen was awarded the T.J. Lafeber, avian practitioner of the year award at the Association of Avian Veterinarians.

Dr. Amanda Darbyshire received her DVM in 2016 from The Ohio State University. She began her journey as a non-traditional student years after obtaining her undergraduate degree. It was her passion for the field of lab animal science, cultivated by her positions as a Research Assistant and Animal Care Technician at The Research Institute of Nationwide Children’s Hospital, coupled with her desire to contribute more to science, and society that drove her to pursue continuing her education at Ohio State.

Throughout her time at Ohio State, residency at Vanderbilt, and career at Purdue Universities, Dr. Darbyshire has earned numerous scholarships, awards, and honors, including the Boehringer Ingelheim Summer Research Mentorship Award. She earned the American College of Laboratory Animal Medicine Foster Award in 2020 for obtaining the highest score on the American College of Laboratory Animal Medicine (ACLAM) certification examination that year on her first attempt. Since then, Dr. Darbyshire has earned a position as Chair of the ACLAM Exam Resources Committee and is currently serving as Chair of the ACLAM Exam Committee. In addition, she is on the Board of Directors for the American Society of Laboratory Animal Practitioners (ASLAP) and the Indiana Branch of the American Association for Laboratory Animal Science (AALAS).

Dr. Thomas Herdt received his DVM degree from The Ohio State University in 1973 and had an outstanding career as an educator and clinician scientist. He is highly regarded as an internal medicine specialist with considerable expertise in the management of metabolic and nutritional diseases in dairy cows. After completing his residency at the University of Minnesota in Large Animal Medicine, he joined the faculty of Michigan State University (MSU) where he spent a career spanning 40 years.

He was Chief of the Nutrition Section of the MSU Animal Health Diagnostic Laboratory (now known as the MSU Veterinary Diagnostic Laboratory), which was and remains one of the largest and most complex veterinary diagnostic laboratories in the U.S. Under Dr. Herdt’s leadership, the Nutrition Section retained and expanded its national and international reputation in the veterinary community and served as a reference laboratory. In addition, he also served as the Chairperson of the Department of Large Animal Clinical Sciences for 6 years. During his time as chairperson, he instituted the Training Center for Dairy Professionals program, which received accolades in two accreditation reviews of the MSU College of Veterinary Medicine. Working with a faculty colleague, Dr. Herdt developed many innovative assays that provided essential information for the treatment and management of nutritional diseases in numerous domestic and zoo animals. He was highly successful in publishing and presenting his work at various scientific conferences. Heauthored the gastrointestinal sections of the first through sixth editions of Cunningham’s Textbook of Veterinary Physiology edited by Bradley G. Klein.

Dr. Herdt was also active in his specialty college, the American College of Veterinary Nutrition, where he served as President and Chairperson of the Board of Regents.

Because of his exemplary leadership over 25 years, the MSU Veterinary Diagnostic Laboratory’s nutrition section provided outstanding service to referring veterinarians and animal owners.

Dr. Lorraine Kogut Jarboe graduated with her DVM from The Ohio State University in 1979.  While there, she met and married Dr. Daniel Lee Jarboe in 1977 after he received his DVM.  Her husband had a four-year commitment to the US Army Veterinary Corps, so Lorraine also joined the US Army Veterinary Corps to, in her words, “better understand the acronyms.”  She learned that the benefits of a couple being in the Army were not twice the benefits of being in the Army, in 1982 she transferred to the Individual Ready Reserve.  She credits her Army training with honing her organizational and leadership skills.

Dr. Jarboe practiced mostly in Richmond, VA, and Silver Spring, MD, while her husband pursued his training as an immunologist.  In every small animal practice where she worked she was instrumental in establishing practice manuals, standing operating procedures and consistency in record keeping.  While her husband pursued his PhD at Medical College of Virginia, she pursued veterinary specialty certification with the American Board of Veterinary Practitioners (ABVP) in Companion Animal Practice.  She was also very active in the American Association of Feline Practitioners (AAFP) and Academy of Feline Medicine.  

She spent five years overseas, having a small house-call service in Rio de Janeiro for the ex-pat community and then, in Bangkok, was a contractor setting up quality control standards for a specimen processing laboratory for HIV research. After returning from Bangkok, Dr. Jarboe joined a brand-new practice that was a merger of two local veterinarians and was instrumental in getting its AAHA accreditation and setting up practice manuals and operating procedures.  She became active in organized veterinary medicine, eventually becoming president of the American Board of Veterinary Practitioners (ABVP), and was instrumental in encouraging the development of alternate methods of recertification.  She later became president of the American Association of Feline Practitioners (AAFP) and served as its representative on the Clinical Practitioners Advisory Committee of the American Veterinary Medicine Association (AVMA).  Dr. Jarboe also participated in item writing, item review, and examination review of certifying/qualifying examinations of the ABVP, AVMA, and the National Veterinary Licensing Board.

In 2005, after finally staying in one house for 10 years, she and her husband retired to Fort Walton Beach, FL (aka ‘paradise’) where she did some relief work, especially at the local humane society.  She now spends most of her time planning travel, having traveled to more than 100 countries.
