Ona was born and raised in Maun, Botswana. His passion for the natural world was fostered at a young age when he had opportunities to visit Moremi Game Reserve as well as several trips to Lake Ngami. After finishing school, he joined the Botswana Predator Conservation Program as a field assistant. His regular interactions with animals under study such as lion, hyena, leopard, cheetah and African wild dog fueled his growing interest in wildlife and conservation. Following the urge to work in an environment where he could engage with both people and wildlife, Ona pursued a guiding career beginning in 2007. He would spend almost two years at Kalahari Plains Camp before moving to Duma Tau Camp and eventually joining Natural Habitat Adventures.

 Ona is a keen photographer and an aspiring wildlife photojournalist. His images and articles regularly appear in numerous travel magazines including Peolwane, the Air Botswana in-flight magazine, Discover Botswana, the annual publication of the Botswana Tourism Board, and Travel Ideas magazine in South Africa. Through his photography, he is an ambassador for his country, with the pinnacle so far being an invited guest speaker at the Wild Shots Wildlife Photography Symposium in Cape Town in 2013. His passion for photography has also cultivated a major interest in animal behavior and behavioral ecology, which are integral focuses of his work as a guide. 

Ona enjoys leading walking safaris where the focus is on small, close-up macro life that one would completely miss while traveling in only in a vehicle. He is also a keen birder who participates in various birding forums around southern Africa. Another important dimension of Ona's multifaceted role as a guide is his mentorship of younger, up-and-coming guides, whom he seeks to inspire as he travels through various safari camps.
