Roseann Beggy Hanson is a native of southern Arizona, and grew up in the rural Tanque Verde Valley east of Tucson.

She studied journalism and ecology and evolutionary biology at the University of Arizona, and has worked in the American Southwest, Mexico, and East Africa as a conservationist, naturalist, and writer for non-profits for over 30 years.

With her husband, Jonathan, she has authored over a dozen natural history and outdoor books, including the Southern Arizona Nature Almanac and San Pedro River: A Discovery Guide. Their Ragged Mountain Guide to Outdoor Sports won the 1997 Outdoor Book Award and their 50 Common Reptiles was cited for Interpretive Excellence by the National Park Service in 1997.

Roseann is also a lapidary and metalsmith, creating one-of-a-kind gemstone and precious metal jewelry. She has sold her creations under the name Desert Rose Design Studio online and at galleries throughout the West. Currently, her jewelrymaking is limited to custom orders and a small number of web sales.

Roseann began ConserVentures LLC as a consultancy to assist small non-profits with development and communications. Clients included African Conservation Fund, South Rift Association of Land Owners, Uaso Ngiro Baboon Project, Biosphere Expeditions, and several other businesses and conservation efforts. 

In 2009 ConserVentures expanded to include the hugely successful adventure travel event Overland Expo, with a mission that strongly emphasizes the connection between exploration and conservation of the world’s natural and cultural resources. Proceeds from Overland Expo, held each May in northern Arizona and October-November in the Eastern US, support in part ConserVentures Charitable Organization, which was founded by the Hansons and a small group of like-minded friends.

Roseann is an associate with the University of Arizona School of Science, working as art and science program coordinator at the Desert Laboratory at Tumamoc Hill, and was named a Fellow of both the Explorers Club in the U.S. and the Royal Geographical Society in Great Britain for her conservation and expedition work.

Jonathan and Roseann celebrated 34 years of marriage in 2018; they share their remote, off-the-grid property 35 miles southwest of Tucson, Arizona, as well as a house in the historic Catalina Vista neighborhood, and work together on books, their event Overland Expo (which was acquired by Lodestone Events in late 2018) and ConserVentures.org.
