[the following feedback was left on my Virtuoso profile feedback, and I've copied it here.]
Derek is the very best travel agent.
Derek has arranged 9 trips for us and each trip has been excellent and without any problems due to his great expertise. I would not use any other travel agent but Derek and would very highly recommend Derek to other travelers. He is very friendly, knowledgeable and professional.
Derek has first hand knowledge of many of the places that we traveled to.
Derek will surely be your number 1 travel agent in the years to come.
