Leslie DeeAnn knows what it takes to create and manage a large business. She started her first company, an industrial chemical business, with her family in the 1970s and was soon supporting over 20 salesmen and manufacturing over 400 chemicals and products for some of the largest hotels, restaurants, universities, and grocery chains in the West. Though her company grew to incredible proportions, Dee's goals changed after she discovered the number of potentially harmful chemicals contained in most women's hygiene and general consumer products. In 1987, Dee and her family started a new business—this time in the network marketing industry—in hopes of spreading the message about potentially harmful product ingredients and providing high-quality, safe products for consumers. Dee's efforts paid off when, after only a short time, her message had compelled some of the largest product companies to begin removing potentially harmful ingredients from their formulas. It took some big conglomerates almost 20 years to improve their products, but many have done it. 

By 2000, Dee's company was bringing in nearly $700 million dollars in sales and competing against big guns like Amway, Nu Skin, and Herbal Life. Dee played a significant role throughout the company's development, acting as both co-owner and CFO. Though she wore many hats, she was never afraid to get out in the warehouse and work with all the employees. Also during this time, Dee started her own product line for her children and wrote a children’s book titled Child Development Made Easy. Dee's contribution to the business community was so influential that she was honored as the first woman to be featured on the cover of Tycoon Magazine in their winter 2000 issue. In 2001, life took a different turn, and Dee had to sell her company against her deepest wishes. She moved on, however, knowing that her next company would have the number one Do No Harm products and would be a leader in the aid of impoverished children and adults around the world.

Dee's influence in Trivani is unmistakable. In November 2007, Dee and her son Bob brainstormed the idea for a humanitarian-business model and how it would work within a network marketing company. Dee has been the financial backing since the inception of Trivani and continues to act as Trivani's co-founder and supreme advisor. In addition, the Trivani Foundation has frequently partnered with Dee's personal humanitarian foundation, Leslie DeeAnn Foundation, to implement effective projects like facial reconstructive surgeries in the Philippines, medical clinics for adults and children in Kenya, and primary and secondary schools around the world. Throughout her years in the business world, Dee has become very outspoken about what she has learned and studied in the last 33 years about chemicals and the potential harm they can do. She wants nothing more than to educate as many as possible about harmful ingredients, and Trivani has become a way to continue to spread the message to consumers and companies everywhere.
