Founder and current reviewer
George Lambroglou, RN
George is a Registered Nurse with experience across oncology, haematology, medical and surgical nursing, intensive-care transition training, clinical supervision and nurse preceptorship. He created MedMaths after seeing the same gap between fast calculators and understandable teaching during nursing education and clinical work.
