I graduated from the University of South Florida with a Bachelors in Psychology and spent ten successful years in an international corporate environment where I attained outstanding awards in sales, marketing and customer service. Then I moved to Paradise where I am now involved in the mortgage and real estate industry. Marathon is very special to me. It is a wonderful, tight-knit community on a chain of beautiful, tropical islands. Marathon has been my home for ten years and I am very proud to be among its residents. My diverse experience as a business owner, corporate manager, officer for Habitat for Humanity of the Middle Keys, along with my expertise in the latest marketing tools and my genuine love of people, have given me the knowledge and ability critical for the real estate profession. I believe in impeccable customer service, listening to your needs and working tirelessly on your behalf. Give me a call and I’ll help you find your own piece of Paradise!
