Marc Swank is a marketing expert with almost 25 years working with companies to grow brands, traffic and sales. He began his career in the advertising agency business with clients in the medical, retail, banking and agricultural categories. Then, moving to the corporate side, Marc ran the marketing for Eyemart Express, an optical retailer. During his 16 years with the company, Eyemart’s unit count tripled and its revenue more than doubled. Most recently, Marc spent two years as the Vice President of Marketing with a medical device startup, an experience he considers invaluable.

His expertise in target marketing grew from his early days in direct mail and was honed as he directed over $150 million in media investment during his tenure with Eyemart Express. However, he considers his real contribution to be the group of creative, marketing and media professionals that he has had the chance to recruit and mentor over his career.

Marc is a proud graduate of the University of Texas where his greatest accomplishment was convincing Layne, his wife of 23 years, to marry him. The couple has two children, Cameron and Emery.
