“Jaan is truly a pleasure to work with, his experience and expertise is wide and covers just about all the scenarios one could possibly throw at him. Producing, as he does, 'works of art' with words - he genuinely adds value where others may just go through the motions. I cannot recommend him highly enough. He clearly cares about delivering a result and will likely suggest 'that clause' you didn't even know you must have. ”
