I have worked collaboratively with Trang on perhaps the most complex and comprehensive cross-border client matter of my 45-year legal career. Her attention to detail and keen understanding of tax and legal matters and holistic approach with the client brough the client huge value and benefit.
I am grateful to have had the opportunity to work so closely with her on this lengthy cross-border project. As a result, I now regularly share other client opportunities with Trang.
