Office: 919.513.6439

Greg received his B.A. in biology from Gettysburg College in 1981, an M.S. in biology with a concentration in marine biology from Northeastern University in 1985, and a V.M.D. from the University of Pennsylvania School of Veterinary Medicine in 1988. He worked for a large wholesaler of ornamental fishes before joining the faculty at the North Carolina State University College of Veterinary Medicine in 1993, where he is Professor of Aquatic Animal Medicine and an Assistant Clinical Sciences Department Head. He is a diplomate of the American College of Zoological Medicine and was named 2007 Exotic DVM of the Year by Exotic DVM Magazine. In 2012 he received the William Medway Award for Excellence in Teaching from the International Association for Aquatic Animal Medicine.

Greg is an author on over 100 popular and scientific articles about invertebrates, fishes, amphibians and reptiles and speaks locally, nationally and internationally on these subjects. He’s also authored or co-authored 25 book chapters related to veterinary medicine of the above-mentioned taxonomic groups and edited or co-edited four veterinary textbooks: Self Assessment Colour Review of Ornamental Fish (Manson Publishing and ISU Press, 1998), Self Assessment Colour Review of Ornamental Fish & Aquatic Invertebrates (CRC Press, 2017), Rapid Review of Exotic Animal Medicine and Husbandry (Manson Publishing, 2008), and the multiple award winning Invertebrate Medicine (Wiley-Blackwell Publishing, 2006; 2012).

He and his wife, Dr. Diane Deresienski (also a veterinarian), live in Raleigh with their engaging dog Vegas and a 40 year-old ball python named Roscoe.
