Halliee Ng

Halliee Ng | Porsche Pro

Halliee played with boxes upon boxes of toy cars when she was young. Whether she was simply pushing them around while imaging she was driving in a race or simulating an intense crash scenario- her passion for cars was slowing growing.

Although it may be considered the smallest act of kindness and it takes little to no effort on our part, it has the power to brighten someone's day", she says. For this reason, you'll always see her with a smile on her face- living up to her motto: "Great customer service begins with a smile".
