I'm Here to Help You

Don't be afraid to reach out.
My name is Karen Holmes. I was born in the U.K. and I have lived in the mid-west United States for over twenty years. I joined Amazon as a 3rd party seller in 2009. I love the opportunity and freedom that comes with running your own online business. There is always something to learn and new challenges. When I am not working on mine or someone else's business, I enjoy time with my family and travelling..
