If I don't fit your needs, have a look at the guest speakers below. While they are friends, I have heard them speak on several occasions and I feel comfortable in recommending them. Click on a name to go to their website.
An enthusiastic mountaineer. Has summited Everest and provides motivational and mountaineering lectures. Very personable and with a dry sense of humour. To use a Scottish turn of phrase, "he could blether for Britain". Divides his time between the UK and US.
John is an expert on South America and has led many canoe expeditions there, as well as in Europe, Africa, Canada and the US. The film ‘John Harrison Explorer’ was made for the ‘Voyager’ series by National Geographic in 1991, about a canoe journey on the Rio Ximim-Ximim in Brazil.
Angus is a professional geologist, rapidly establishing a reputation as an expert in explaining Scottish geology. He runs day and residential geology trips, provides training in geology interpretation, and can provide talks on Montserrat, where he monitored the volcano as part of the international team of scientists.
John exudes bonhomie and whenever I have followed him at a venue, he is always spoken of warmly, and is always repeat booked. He is also a radio broadcaster and travel author. He can be out of the country for several months at a time but maintains good communications while away.
Paul is a BBC TV Presenter, field logistics expert, polar guide, professional diver & instructor, mountaineer, and yacht skipper. He has also been awarded the US Navy Polar Medal for his work with NASA and the Mars Lander project in Antarctica. He's a born enthusiast (as his TV programmes demonstrate) with a genuine warmth and interest in people around him.
A dry, modest man who has little to be modest about. He has been to the North Pole and the South Pole six times each, and has 14,000 miles of polar travel under his belt. He has advised on TV dramas documenting polar travel, and has also travelled across deserts by camel.
Captain William Wells
Captain William Wells, Master Mariner, is a former ship's captain and commercial marine pilot, whose career at sea lasted just short of 49 years. I do know him but haven't heard him speak. I have heard though, from very discerning sources, only good things about his talks.
