Small Animal Ultrasonography

Dominique Penninck graduated from the Veterinary school at the University of Liège (Belgium) in 1981.  After a residency at University of Davis, California (1985-88), she joined the radiologist team at the Cummings School of Veterinary Medicine, Tufts University.  She is diplomate of the American College of Veterinary Radiology, and the European College of Veterinary Diagnostic Imaging.  She received her clinical PhD from the University of Liège in 1998.  She has been invested in teaching ultrasonography to students, interns, residents, and practicing veterinarians, adopting and developing new methodologies to facilitate the learning of this modality.  In her spare time, she enjoys spending time with her grown up kids, traveling, discovering the arts, taking photographs, and dancing!

Marc-André d’Anjou became veterinarian in 1996, graduating from the University of Montreal, before completing a residency program in diagnostic imaging at Tufts University leading to his board-certification from the American College of Veterinary Radiology in 2003. He was faculty at the University of Montreal for 10 years before founding Animages in 2016. He kept his teacher hat, lecturing to students and veterinarians, supervising interns and residents, and creating eLearning environments for small animal diagnostic imaging. Marc-André spends his free time traveling and chasing light and his kids with his cameras, and playing around with multimedia softwares. As opposed to Dominique, Marc-André is not a formidable dancer.
