Dr. Patterson is a board-certified Mayo Clinic trained clinical immunologist with over 30 years of experience in treating patient with primary immune deficiency/inborn errors of immunity (PID/IEI).

As defined by the Jeffrey Modell Foundation:

Primary Immunodeficiency, also known as Inborn Errors of Immunity, is a group of more than 550 genetic disorders of the immune system that are chronic, serious, and sometimes life-threatening. Primary Immunodeficiencies/Inborn Errors of Immunity occur when genetic mutations cause one or more parts of the immune system to not work properly. A weakened immune system increases the risk of frequent and severe infections, and potential organ damage.
