Throughout the years, she has helped numerous growers and assisted the sales team in many product demonstrations. The growing media industry is no mystery for her. “I do enjoy the fact that no two interactions are the same even if the ‘issue’ is the same, since each client has a different perspective of what they are doing and how it impacts their results.’’ All she wants is to accompany you to the best of her knowledge!
