Alan wrote his first guidebook Peak Limestone in 1992. During the 90s he gradually developed Rockfax as a business taking over from the start made by Mick Ryan. This included the ground-breaking Pembroke guidebook of 1995, the very successful and popular Costa Blanca, Mallorca and El Chorro guidebook of 1996. Into the new millennium the business grew and as more people were taken on Alan switched to more of a publishing role. He now oversees the sub-editing of all the publications and helps write the odd one. He enjoys all types of rock climbing, particularly trad sea cliffs and French and Spanish sport routes.
