About Us


Currently, Carl and Nina are the team at One Plus One but they have lots of support from Sarah Judson, Marcelo Crespo and April Paulson. Kudos to Jesse Bates for helping get the site up and running. ♥♥♥

Carl is a rancher from northern Colorado with experience in livestock and irrigated crop production as well as manufacturing of both ceramics and light machinery. He served as a volunteer in the Bolivian Andes, working with Agua Para La Vida on rural development projects for small Indian communities where his interest was in helping with the problems of Bolivian subsistence farmers and their families. Carl formed One Plus One to continue work he had done for APLV in Bolivia since 1993. On top of that, Carl is also a “guerrilla” painter of small oil paintings, and from time to time has used the proceeds from his paintings to support charitable work in the third world. These days, he is the manager at Guerrilla Painter but spends a great deal of his time in the pottery at his family's ranch in northern Colorado.

Nina lived in Bolivia for a year in 1994 and went to school in Cochabamba when she was 16. She did some volunteer work there in 1999 and 2000 teaching home canning. Since then, she's been busy with life: a great big adventure that she has shared with her husband, Marcelo (who she met in Cochabamba once upon a time) and their two children, both of whom are on the Autistic spectrum. In 2019, Nina took up Urban Sketching and sketched her way around family, kids, work, and a trip to Latvia. In 2020, Nina's illustrations were published in Enjoying the Work, a book of poetry by George N. Wallace. Also in 2020 and 2021, Nina offered original sketches in exchange for donations for Covid relief. This has morphed into her current projects to fundraise for Ukraine and Unified Sports. 

One Plus One

a Colorado Nonprofit Corporation

One Plus One (“1+1”) is a very small public charity - 501(c)(3) founded in 1996.

“1+1” was formed to continue volunteer work which Carl had been doing for Agua Para La Vida (APLV) in Bolivia since 1993. These days, our focus has shifted a little but we are still dedicated to volunteering our time to help others.

Free Little Art Gallery

Watercolor Pencil and ink on bristol paper, 2.5" x 3" 

This sketch is of an actual mini art gallery here in Fort Collins, Colorado (I'll give you one guess as to who runs it ☺☺☺). Free Little Art Galleries are a cousin to Little Free Libaries and are taking off about the country. They are a fantastic way to share mini art in a neighborhood. The Mountain Avenue Market (aka Fort Collins Food Coop) hosted an Itty Bitty Art Show November, 2021, through February, 2022. I was able to mount this sketch in a mini dollhouse frame on an easel and found a space back in the bulk room to desplay it. This was a fantastic concept and hunting out the itty bitty art around the market was a little bit like an Easter egg hunt.
