Professional recommendations

Brian was the driving force behind delivering an autoinjector for Cimzia patients. His generosity, support and impact over the years have been exceptional.
David HarrisonBusiness Leader
Brian led our drug delivery business for three years from late 2004 until the end of 2007. During that time, he took the business to the next level by growing the team and extending our client list. He also championed some innovations which have been very commercially successful and his nose for the value of an innovation is impressive. What has been remarkable has been the durability of what he built which has continued to go from strength to strength since he moved on.
