Mannatech Chief Operating Officer Peter Griscom Resigns Weeks After Promotion
Mannatech disclosed in a regulatory filing that Chief Operating Officer Peter Griscom has resigned, effective August 8, 2025. The company said Griscom notified Mannatech and its board of his decision on July 21, 2025.
Griscom's departure comes less than a month after the Flower Mound, Texas-based nutritional supplement company announced his promotion to chief operating officer in late June. The filing, signed by Chief Executive Landen Fredrick, did not give a reason for the resignation or name a successor.
The leadership change comes as Mannatech contends with falling sales, particularly in Asia, and a shrinking network of independent associates and preferred customers.
