Gary Sia
Director of Sales


With nearly 17 years of experience under my belt, I've had the privilege of witnessing and contributing to Callbox's remarkable journey. I take immense pride in being the top revenue earner, and I've always been passionate about client acquisition. In fact, it's one of the key factors behind Callbox's success today. In 2021, I had the honor of being recognized as Callbox's Employee of the Year, which was truly humbling. With an extensive network of nearly 17,000 connections worldwide, I'm committed to forging new partnerships and driving growth.
