Raised in Philadelphia, Pennsylvania, Dr. Tomaszewski received his undergraduate education from LaSalle College in 1973. He attended the University of Pennsylvania School of Medicine and received his medical degree in 1977. After finishing medical school, he completed an internship and residency in anatomic and clinical pathology at the Hospital of the University of Pennsylvania in 1982. During that training he had special concentrations in immunology, HLA testing, and nephropathology. 

Subsequently, he completed a fellowship in surgical pathology in 1983, before joining the faculty in the Department of Pathology and Laboratory Medicine at the University of Pennsylvania. In his first year of appointment, he was given the opportunity to do a specially arranged fellowship in nephropathology with Dr. Conrad Pirani at Columbia University.

Following his training, the doctor attained board certification in anatomic & clinical pathology through the American Board of Pathology (ABPath). The mission of the ABPath is to promote the health of the public and advance the practice and science of pathology by establishing voluntary certification standards and assessing the qualifications of those seeking to practice the specialty of pathology.

Pathology is a branch of medical science that involves the study and diagnosis of disease through the examination of surgically removed organs, tissues, bodily fluids, and in some cases, the whole body. Pathologists are physicians who specialize in the diagnosis and management of diseases by laboratory methods.
