Diana was born in Halifax, Yorkshire, into the Maclean family of Scottish descent and has the added advantage of an American mother. She moved to Kenya to start Insiders Africa together with her now husband Alex (they married at St Bride's, London, in 2006), working initially to establish their traditional style of mobile walking safaris in the Masai Mara.

Diana has had a varied career after graduating from Central Saint Martins’ in London with a degree in Fashion Communication and Promotion. Via journalism and photography, PR and marketing, she has worked at and written features for many different magazines and newspapers, including: the Financial Times magazine, Telegraph, Vogue, Harpers Bazaar, Country Life, Food & Travel, Scotland on Sunday, etc. Also, PR for photography and illustrated books for publishers such as Assouline and Thames & Hudson, and PR for the Michael Hoppen Galleries which deal in vintage and contemporary fine art photography.

With passions for wilderness, animal behaviour and photographing unusual breeds of horse, Diana learned what has become known as ‘horse-whispering’ from Monty Roberts (“The Man Who Listens to Horses”) and Kelly Marks, leading to a year living in Argentina as a professional wild horse tamer.

Since moving to Kenya, she has created the Insiders Africa and Safari Courses websites; developed the Photographic Safari Course for guests to go on safari learning from professional photographers; produced beach and bush fashion shoots for Marie Claire France and worked with Alex on their walking safaris and the building from scratch of Ol Pejeta Bush Camp. All of her previous experience in fashion, photography, journalism, horse-whispering and even living in Shepherds’ Bush has somehow become curiously useful for every aspect of what she does now.

The current J.A. Hunter is known as Alex, and with his wife Diana, owns and runs Insiders Africa Ltd and Ol Pejeta Bush Camp, the only owner-managed bush camp in Laikipia. His grandfather, the original J.A. Hunter, was probably the most famous professional hunter in East Africa during the early-mid 1900s. For over fifteen years, he hunted with maharajahs, millionaires and other famous sportsmen of the day once famously refusing to take the Prince of Wales because he already had another booking which he, quite rightly, decided to honour instead.

John Alexander Hunter was born in Dumfries, Scotland in 1882, one of 5 children of farmer David Hunter and his wife Elizabeth. J.A. became a keen, accurate shot by his teens, and decided that agriculture in Scotland was not his calling so with a distant relative who was a dairy farmer in Kenya, sailed for Mombasa aged 26. Arriving in 1908 with some clothes and a Purdey shotgun, he worked on their farm but then found employment on the railway.

After fighting with distinction in the First World War in German East Africa (Tanzania) he founded a transport company delivering supplies to remote regions. In 1918 he married Hilda Bunbury and they had six children. Their eldest son was Gordon Hunter, Alex's late father. In 1920, he collaborated on setting up the Nairobi gunsmiths Shaw and Hunter, with the famous gunmaker Morrison Shaw. Soon after he joined the colonial government game department and became a professional hunter known as a PH.

Clive Ward’s profound knowledge of and sheer passion for mountains has made him a unique and special guide with virtually unsurpassed climbing and trekking experience. He has climbed Kilimanjaro over 70 times, and Mt Kenya over 50 times. Clive began general mountaineering and technical climbing at the age of fifteen, in England’s Lake District. In his twenties, he emigrated to South Africa, eventually moving to live in east Africa; he is now resident in Kenya.

His climbing career has led him on numerous trekking and climbing expeditions to many of the world's most remote places in countries including: Alaska, Patagonia, Peru, Bolivia, Nepal, Tanzania, Rwanda and Uganda.

For the past thirty-five years, in Southern and Eastern Africa Clive has visited some of Africa's most fascinating wilderness regions as a mountain, bush and tribal lands trekking guide. In particular he has specialized in walking safaris on Mount Kenya and Kilimanjaro, the Ruwenzori Mountains in Uganda, and lowland bush treks along the Tsavo and Galana rivers in Tsavo West and Tsavo East National Parks in Kenya.
