The first dermatologist at another hospital system told me that he doesnâ€™t see anything. I pushed for a biopsy, which I was told showed nothing. They left a message on my voice mail telling me it wasnâ€™t necessary to schedule a follow up appointment. Dr Greta Janss heard me, took additional biopsies, determined that there is a concern and has provided the professional care that I am in need of. It is the feeling of confidence that I am experiencing, knowing that I am in the right place with the right doctor and care team with the right care plan that make it easy for me to refer Dr Janss to others.

Disclosures

Gerta S. Janss, MD reported no external professional relationships for calendar year 2023.

External Professional Relationships

Pharmaceutical, device, and biotechnology companies frequently collaborate with basic scientists and physicians within an academic medical center to help advance science and improve patient care. These relationships are important in achieving scientific breakthroughs and in establishing the effectiveness and safety of promising new therapies. In order to assure objectivity in clinical research and patient care, the Northwestern University Feinberg School of Medicine (Feinberg), Northwestern Memorial HealthCare, Children's Hospital of Chicago Medical Center, and the Shirley Ryan AbilityLab have adopted integrity policies that require research and clinical faculty (in full-time, part-time, and unpaid/voluntary categories) to report compensated and uncompensated external industry relationships. Patients are encouraged to discuss these disclosures with their physician as well as to inquire as to how these relationships are overseen by Feinberg. To learn more about our Disclosure and Professional Integrity Policy, and the conflict of interest policies of our joint affiliate survey partners, please go to our Office for Regulatory Affairs Policies page.
