Dr. Lori Cesario
Board-Certified Veterinary Oncologist
Dr. Cesario is originally from Long Island, NY. She received a Bachelor's degree in animal bioscience from Penn State University before attending veterinary school at Ross University and completing a clinical year and the University of Wisconsin-Madison. After veterinary school, she completed a one-year rotating internship at the University of Illinois, followed by a one-year oncology internship at NC State. She then moved back to the Midwest to complete a three-year medical oncology residency at Michigan State.
In 2013 she moved to California to practice oncology and has worked in specialty clinics as a staff oncologist and locum oncologist in Ventura and throughout California.
She is passionate about giving pets with cancer the best quality (and longest length) of life possible and has sought out advanced training to help provide this for her patients. She is also very passionate about hospitality in healthcare and understands that a cancer diagnosis in a pet is something that the entire family experiences. Her goal at Hope is to improve the experience for everyone involved.
When she takes a break from working on or in her business, she enjoys hiking in the beautiful Ojai Valley, plant-based cooking, and just having some downtime :)
