Thelma Pepper's first exhibition titled "A Visual Heritage, Images of the Past, 1900—1930" featured prints from her father's and grandfather's negatives. It was shown at the Macdonald Museum in
Middleton, Nova Scotia in 1983 as well as the
Diefenbaker Centre in Saskatoon, Saskatchewan from 1986–7. She volunteered at a local nursing home after her children left home and also bought a top-of-the-line
Rolleiflex camera. She joined a local artist-run centre called the Photographers Gallery, and began participating in exhibitions. While volunteering at the local seniors’ home, she began interviewing and photographing the women who lived there. This work, led to the exhibition "Decades of Voices" in 1996. Pepper's next project from 1996 documented the lives of 10 pioneers living along Highway 41 in
Saskatchewan, which led to an exhibition titled "Spaces of Belonging: a Journey along Highway 41.” “Untie the Spirit" was a work Pepper compiled in 2006 to document life at the Sherbrooke Community Centre, a long-term care facility in
Saskatoon. She worked with artist Jeff Nachtigall when the Centre incorporated healing arts as part of treating the whole person through art, music, children, pets and plants. A 2009
National Film Board documentary
A Year at Sherbrooke chronicles Pepper and fellow artist
Jeff Nachtigall, as they work with the residents of Sherbrooke Community Centre. Her book
Human Touch: Portraits of Strength, Courage & Dignity was shortlisted for the Book of the Year at the 2011 Saskatchewan Book Awards. The book included a collection of over 50 portrait images selected from Pepper’s entire body of work of 2,350 printed photographs. The book includes essays by Elizabeth Philips, Grant Arnold and poetry by
Lorna Crozier. Pepper's centenary in 2020 was marked by the publication of a biography titled
Thelma: A Life in Pictures by Saskatoon writer Amy Jo Ehman. The book includes photographs of Pepper, from childhood to the present, alongside some of the portraits she took of others. == Awards ==
