[4][1] Greenlees maintained a professional artistic career while continuing to teach privately, which was in direct opposition to the policies of the Glasgow School of Art.
[1][2] Greenlees was a founding member and first president of the Glasgow Society of Lady Artists.
[4] The society was formed early in 1882 during a meeting at the studio Georgina shared with her father at 136 Wellington Street, Glasgow.
[10][2] The society was the first of its kind to be formed in Scotland and represented the need for women art practitioners to exhibit their work and socialise with other artists.
