Susan Domizi, President and Founder

Susan Domizi started her career in the horse industry as a working student sleeping in a hayloft because the house she was to live in wasn’t finished yet. Still, she recalls crawling into her sleeping bag each night to sleep with the mice and the barn swallows and feeling privileged to be in the employ of a top horse professional, poised to set the show world on fire with her horsemanship prowess.
Though Susan’s original dream was never fulfilled, a better one came true. Her talented event horse [Hull] was plagued by shelly feet. When she discovered a seaweed-based product from Ireland that appeared to help him, she was ecstatic. However, the quality of the imported product was extremely inconsistent. Trained as a biochemist, Susan felt she could do better. She began an odyssey that resulted in the formation of a nutritional supplement company known as SOURCE, INC.

Domizi’s intense research into the benefits of seaweed meals led to a product whose benefits not only poor feet but also weight problems, coat condition, appetite, stress, and other nutritionally related conditions are now renowned among horsemen. Along the way she has developed harvesting and drying techniques that make the various seaweed meals used in SOURCE among the highest quality in the world. She helped launch an organization dedicated to protecting precious coastal seaweed beds from pollution and over-harvesting and built a strong company able to prevail in the market against copycat competitors.

Susan attributes her success to an unwavering commitment to quality control, fair and equal treatment of those she meets in the business world, and respect for her customers. From the very first pail, Domizi has sold SOURCE with a money-back guarantee, the first of its kind in the horse industry. She points with pride to a shelf full of notebooks stuffed with letters from joyous horse owners whose horses improved when SOURCE was added to their diets.

Susan’s training as an analytical scientist gave her a model on which to build her success. “Education in any field is useful because it teaches you how to learn and how to seek the answers you need,” said Susan. Every step in the development and growth of her company has been supported by careful research, consultation with experts, and meticulous planning of all details. SOURCE’s longevity is legend in a market where many nutritional supplements blaze as a feeding fad for several years only to be discarded for lack of consistent results. Indeed, clamor among its customers has led to nutritional supplements for both humans and dogs based on the original SOURCE formula.

Susan's inspiration for beginning her life's affair with seaweed: HULL
This treasured portrait of HULL was given to Domizi as a wedding present by artist Jan Royce Conant. Ms. Conant also created the trademark SOURCE Seahorse logo.

Like many in the horse industry, Susan works long and hard to achieve success. In fact, managing her business now leaves no time for riding or a horse of her own. Still, Susan finds fulfillment in the stories about horses with nutritional problems whose lives were turned around by her product. She points with pride to the photo of a highly successful, famous racehorse whose dam was fed SOURCE and who received SOURCE from the time he was born. She smiles as she tells of horsemen who whisper in the shedrows about their “secret” for raising runners better able to withstand the rigors of racing than their peers. And it all started with her love of a big-hearted event horse named Hull.
