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. Due to his strong academic and clinical standing at the University of Illinois, Chicago College of Medicine and his developing interest in teaching, Dr. Hoffmann was selected for tutoring fellow medical students in Anatomy, Histology, and Behavioral Science. He also became a substitute teacher in Anatomy and Physiology at a local community college. His strong academic standing at the University of Illinois, Chicago College of Medicine, further qualified Dr. Hoffmann to attend other medical universities as a visiting student during his third and fourth years of medical school in order to enrich and broaden his overall medical training experience. As a result, he received additional training at UCSD School of Medicine, UCLA Medical School, and Stanford University School of Medicine. Later in his third and fourth years of medical school, he would return to the UCSD School of Medicine and the Department of Immunology, Scripps Clinic and Research Foundation where he did many months of research on leprosy with Professor Emeritus, Dr. Irma Gigli.  She is considered to be a world authority in dermatologic and immunologic research. 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. He then attended the Baylor College of Medicine in Houston, Texas from 1985 through 1988 for his residency training in Dermatology where he received his Board Certification in Dermatology.
