Dr. Hoffmann was accepted to numerous medical schools, but chose to attend the University of Illinois, Chicago College of Medicine known for its accelerated basic science learning environment and for providing intensive clinical training within the inner city of Chicago at well known hospitals such as Cook County Hospital. It was there that he spent countless hours in emergency rooms and operating rooms developing many of the surgical skills that he would later perfect in the field of Surgical Dermatology.

He also became a substitute teacher in Anatomy and Physiology at a local community college.

Under her direction, a break-through understanding of leprosy was achieved and the findings were published in the very highly regarded Journal of Investigative Dermatology. From here, Dr. Hoffmann was recommended to the world renowned St. John’s Hospital for Diseases of the Skin in London, England (which has since been renamed, The St. John’s Institute of Dermatology and is now part of the large multi-faculty medical school which includes Guy’s, King’s College and St. Thomas’ medical schools). At the time, the program accepted one dermatology resident from the world per year. Dr. Hoffmann is thankful to Dr. Irma Gigli for her recommendation so that he could attend as an Oversea Student Registrar.

Dr. Hoffmann did his internship in Internal Medicine at St Mary’s Hospital in Long Beach, California, a teaching hospital affiliated with the UCLA School of Medicine.
