One of the best ways of sharing information with people is that of giving lectures, especially when the language is kept free of technical jargon and the presentation makes little demand on previous knowledge. These requirements often are not met, but many years' experience in the field enable me to give talks that (I hope) are both illuminating and inspiring. Within the constraints of geography and my schedule, I am willing to give lectures on topics that I am familiar with. I do charge a modest fee to compensate me for the time invested.
People or organizations potentially interested in a lecture should contact me well ahead of time to check on my availability and the topics that would be of interest.
