About Tracy

After completing her DVM at the Ohio State University, Tracy completed a small animal medicine and surgery internship at the Angell Animal Medical Center in Boston. After a year in private practice, Tracy completed a residency program in small animal emergency and critical care at Angell Animal Medical Center. Following the residency, Tracy earned a PhD in immunology (pathology) at Colorado State University. Tracy’s current research involves investigation and clinical application of mesenchymal stem cells and minimally-invasive methods of improving cardiovascular disease.
