James Whipple founded Northeastern Wildlife in March of 1987 with the objective of providing a source of “non-traditional” animal models of human disease. The first animal model established was the woodchuck (Marmota monax) as an animal model for Hepatitis B Virus (HBV) studies and hibernation research. This was followed by the introduction of opossums for pancreatitis and lower esophageal sphincter (LES) research. In 1991, Northeastern Wildlife became a USDA licensed research facility and has since performed numerous protocols for both the public and private sectors. Since our founding, we have supplied most of the woodchucks used in international studies.
