Who We Are

This program is founded by Drs Karin Sorenmo and Mark Cofone. We are both veterinarians, Karin is a board certified oncologist and recently retired as emeritus professor of oncology from PennVet after 30 years of practicing medical oncology. Mark is a veterinary surgeon and also recently retired from private specialty practice after a long career as an owner and surgeon at VSCD. But we are not ready to leave Veterinary Medicine, and this program will allow us to focus on an area that is near to our heart: Providing care to homeless dogs with mammary tumors, advancing mammary tumor research and through this research advancing breast cancer research. This is where the name “ Lesley’s Place” comes from. We named this program to honor our dear friend and colleague Dr. Lesley King, veterinarian extraordinaire, lover of horses and dogs and our chosen sister. Lesley was diagnosed with stage 4 breast cancer in the prime of life, and she lost her battle after 8 years of fierce resistance. Lesley loved the PennVet Shelter Canine mammary Tumor Program Karin Started in 2009. This Program provided care to homeless dogs with mammary tumors while at the same time advancing knowledge to benefit breast cancer research. Lesley’s Place is a continuation and expansion of this program, and we think she would be pleased. We are in a perfect position to take this on: as an oncologist and a surgeon we have the combination of skills needed and the passion for the work.

Lesley’s Place is an independent non-profit program working from within and under the umbrella of the Veterinary Oncology Services and Research Center in West Chester. All the clinical care for the dogs enrolled in this program will be provided here. This Specialty Oncology Hospital in owned and operated by Dr. Ann Jeglum, also a veterinary oncologist. Dr Jeglum was on faculty at PennVet when Lesley, Karin and Mark did their residencies. In fact, Ann was Karin’s residency mentor during this time. Now we are back together again, and we are grateful that Ann has welcomed us into her practice and allowed us to build this program using her facilities and staff to do so.
