Helping you succeed in tomorrow's world

"The world of public procurement litigation is exceptionally fast-paced, which makes for an exciting and varied practice.  My best skill is probably to delve deep into the detail of a procurement dispute very quickly in order to provide robust, straightforward and commercial advice on the best way forward for the client.  I also enjoy advising on non-contentious procurement issues, which often allows me to build a deeper working relationship with clients on a longer-term basis."
