As Chair of the George Street Association in Edinburgh, I dealt with Mark Rinkus when he was the lead consultant producing a revised concept design for the transformation of George Street. I was impressed with his professionalism and ability to build constructive relations with many different stakeholders.He ably managed a particularly complex assignment given the UNESCO World Heritage status of George Street and the widely varying nature of the many businesses and organisations operating in this iconic street, each with their own requirements for customer access, operating hours, deliveries and loading.Through masterminding an extensive series of business engagement events where they could explain their requirements and him teasing out the scope for adaptation and change, he was able to understand the detail, but never lost sight of the bigger picture. The concept design he produced gained wide acceptance. Perceptive, articulate, persuasive and politically astute, he is someone who will get things done and make a difference.
