Every breakthrough has a birthplace.

A fellowship-trained interventional radiologist, Jeffrey co-developed many foundational procedures in veterinary intervention, including stenting and embolization. Across three decades in academic medicine, he has trained hundreds of residents and fellows and authored more than 100 peer-reviewed publications, along with Radiology Secrets, now translated into 18 languages.

He completed a residency in diagnostic radiology and a fellowship in interventional radiology at the Hospital of the University of Pennsylvania, and earned an MBA from the Wharton School where he remains on faculty. At Genisys, he leads product and partnership strategy, bridging human and animal health innovation.

One of the founding figures of veterinary interventional radiology, Dr. Weisse invented and co-invented many of the discipline's foundational solutions across multiple organ systems. With Jeffrey Solomon, he established the first clinical service of its kind at the University of Pennsylvania and started the specialty's first fellowship program, before joining the Animal Medical Center in New York, where he leads its Interventional Radiology & Endoscopy service.

A co-founder of the Veterinary Interventional Radiology and Interventional Endoscopy Society (VIRIES), he co-edited Veterinary Image-Guided Interventions, the definitive text in the field, and has trained thousands of veterinarians worldwide.
