Clayton Utz
Partner Brisbane

[Katy] delivered excellent work and advice despite being faced with complex and challenging circumstances. Much of what was endured were not ‘normal’ A&D challenges and I think you should be proud of the work you did in overcoming the circumstances and getting this deal across the line.
