Accounts Manager, Gateway Champion Sdn Bhd

"Losing my husband left me facing an uncertain future. Grateful for the support of my late husband's friend K H Oon, he recommended lawyer Derrick, who assigned his partner David to handle my case. Despite initial hesitation, David's patience and reassurance guided me through the legal process. He efficiently settled matters, completing the case in just three months. Impressed by his services, my friends wished for such a lawyer in their own situations.

To me, David is more than a lawyer, he's a friend and someone I can freely reach out to. I now understand the reason to give thanks for everything after experiencing the angels God sent into my life."
