Tuhia he haere tonu mo tenei whitianga - I noho a Isabel Roberts mo nga tau e toru i New York City, e ako ana i te hoahoanga i te atelier Masqueray-Chambers (1899-1901), te atelier tuatahi (atelier ranei) i te United States i whakatuhia hei whakaako i te mahi hoahoanga i runga i nga raina French o te Ecole des Beaux Arts. I whakatuhia e Emmanuel Louis Masqueray; i uru te kaihoahoa Walter B. Chambers ki tenei umanga. Kei te 123 E. 23rd Street, koinei te atelier motuhake tuatahi i whakatuwherahia i te United States. Ko Masqueray te mea tino maumahara hei kaihoahoa o te Whakaaturanga o St. Louis
me te Whare Karakia o Saint Paul i Saint Paul, Minnesota. I kitea a Roberts i roto i te raarangi whakamiharo o nga kaihoahoa o muri ake nei i ako me Masqueray, tae atu ki a William Van Alen, ko ia te kaihoahoa o te Chrysler Building. I te timatanga o te tau 1899, i whakapau kaha a Masqueray ki te whakauru i nga waahine ki roto i ana akonga hoahoanga, a, i whakatuwherahia e ia tetahi atelier tuarua mo nga akonga wahine i te 37-40 West 22nd Street i New York. Ka rite ki te korero i taua wa, "... he tino whakapono ia ki te kaha o nga waahine ki te angitu i roto i te hoahoanga... i te mea ka kaha ratou ki te mahi". I a ia i New York, i noho a Roberts ki te 129 West 96th Street.
