Doris Nathan's family was friends with Carola Trier's
family in Frankfurt, Germany.
They reunited after both families immigrated to the United States. Carola introduced Doris to Dr. Jordan to help with her scoliosis, and later to Joseph Pilates, whom she studied with for a few years. Doris later studied at Carola's studio. In addition to being a Pilates student, Doris was also a good friend of Carola's.
