Joe and Mary Ann hold the unofficial "world record" for the most mountain gorilla treks for any tourist in Rwanda. They have completed over 100 treks each, amassing a photographic collection of mountain gorillas unsurpassed by any other photography team. Joe's mountain gorilla photographs have won awards in the prestigious BBC Wildlife Photographer of the Year competition three times, and both Mary Ann and Joe have had the honor of naming a baby gorilla in Rwanda's annual Kwitza Inza ceremony, perhaps the highest honor in the world of gorilla conservation. Their photo tours to Rwanda have contributed over $1,000,000 to the local economy. Joe has authored 12 books on wildlife/wildlife photography; Mary Ann has written 29 children's books. Joe and Mary spend over half the year in the field photographing, leading photo safaris, and conducting tours to worldwide destinations that typically include five continents.
