Hello, and welcome :)
Why does good design matter? Some things can not be conveyed in words. When someone sees a website or print materials, there is always that question hovering there, “What is this business like? What are these people like?” These visual spaces are like walking into someone's living room. Instant impressions are received to answer these questions. Good design reflects the qualities that give you strength of character as an individual or a business.
As a designer, my job is first to understand your mission, and then through a collaborative process with you, the client, to help you materialize your vision in color and form.
