This year marks a significant milestone for our CEO, Grant Cox, as he celebrates 10 years with GMA Garnet Group.

Over the past decade, Grant’s vision and commitment have guided GMA through a period of global growth and transformation, ensuring we continue to deliver value to our customers while remaining true to our purpose and values.

Reflecting on this milestone, Heinrich Jessen, Chairman Jebsen & Jessen Group, shared:  We have much to be thankful to Grant for. Over this decade of loyal service to GMA, five years each as CFO and CEO, Grant has been leading with perseverance, intelligence and an impressive ability to manage the myriad of moving parts that characterize our garnet business, while building a culture of trust and support and living our values in an exemplary way.”

 At a recent presentation dinner, Grant reflected on his time at GMA, acknowledging “Our people, customers, and partners have been at the heart of GMA’s journey. I am proud of how far we’ve come, and inspired by the potential that lies ahead as we pursue new opportunities for GMA and the industries we serve.”

 We extend our thanks to Grant for his leadership and commitment over the past decade and look ahead with confidence to the opportunities he continues to shape for GMA’s future.
