Founding Story

Opal Cool was created by Tammy Lee, one of Minnesota’s top honored woman business leaders in the health and biotech industry, and is the founder of Xena Therapies, a medical tech company. In 2020, Tammy set out on a mission to innovate effective health and wellness products to support women’s unmet or underserved needs.

Tammy created the Opal Cool line of cold therapy products using a trade secret design and manufacturing process to engineer a cooling temperature that is skin-safe and provides long-lasting cool relief and comfort without any risk of ice burn. Opal Cool’s novel designs are uniquely created through the lens of women’s needs for cool relief where and when she needs it most.

Tammy’s interest in cold therapy began when she suffered from mastitis during her breastfeeding days and today understands firsthand the toll hot flashes can have on women.
