[citation needed] During his time in Stockholm, he also worked as the head of Grabowska, a decorative painting workshop at Karlavägen.
In 1924, Nordmark provided helped restore the church in Mockfjärd, contributing his work for free (pro bono) because of his love for his homestead.
[2] To acquire more knowledge within his field, he made several study trips on the European continent to nations including France, Germany, Italy, and Russia.
Although it is not known when Nordmark started to teach, it is possible that he had a summer art school at his studio in Lomala, Hopewell Junction, New York, already in the early 1930s.
In 1934, Marsh traveled to Lomala to learn the art of fresco painting from Nordmark, in anticipation of his commission to execute murals.
[15]: 114 [16]: 74 Biddle and Marsh employed Nordmark to superintend their mural projects in the Post Office Department Building.
[note 4] He served later as a technical consultant for the Section of Fine Art and supervised mural paintings made by Native American artists.
[19] Biddle spent a summer studying fresco techniques with Nordmark, before he began his work in the Department of Justice Building in 1936.
[17][note 5] Nordmark worked also as a federal artist-in-residence in Pine Ridge Reservation in 1937, where Andrew Standing Soldier was studying under him.
[note 6] The Department of the Interiors's Bureau of Indian Affairs employed Nordmark to teach fresco painting to Native Americans from 1938 to 1943.
[23][note 7] He was working at the Indian Art Center, a program for outstanding students and teachers, in Fort Sill, Oklahoma, from 1938 to 1940.
This was proved by the uniquely individualistic work of Standing Soldier, who was studying again with Nordmark at the Indian Art Center in circa 1938,[note 9] and of the Native Americans, who painted murals in the Department of the Interior Building.
[26]: 85–86 Among Nordmark's other known students at the Indian Art Center were Blackbear Bosin,[24]: 36 Woody Crumbo,[24]: 36 Charles Loloma,[26]: 104 [33] Fred Kabotie[26]: 104 and David E.
[27]: 264 [31]: 311 Some sources[31]: 311 tells that Nailor enrolled with his close friend Houser for one year at the Fort Sill Indian School.
[25]: 202 George Smith "Woogee" Watchetaker[36] and Herman Toppah[33] also studied with Nordmark, but the references do not give any further information about neither the location nor the year.
Later, Jacobson and Nordmark mentored together some Philbrook artists including Crumbo, Albin Jake and Jesse Edwin Davis II.
