I have been incredibly fortunate to work for a great company where I have built a very successful career. At the age of 19, I started as a customer service representative at Graybar, and 29 years later, I am a senior vice president and a member of the company’s Board of Directors. That kind of career path really speaks to Graybar’s culture, and more importantly, to its core values of integrity, employee ownership, long-term view, and customer focus.

My career path has also allowed me to learn Graybar’s business from the bottom up, and has given me the opportunity to benefit from the wisdom and experience of others. Most of this mentoring has been informal; however, it has been an essential part of my career growth. At this point in my career and in my life, I recognize more than ever the importance of investing in the development of others. I’m proud of the things I’ve accomplished, but I want to be remembered as someone who made a positive impact on others, both personally and professionally. I want to help the next generation succeed, not only for their personal benefit, but also for the benefit of the organization, and the communities where we all live and work.

As an example, I recently led the effort to start a women’s networking group at Graybar called WINGs, which stands for “Women influencing Graybar’s Success.” in an industry that is predominately male, I am excited about the possibilities for this group. As it grows and develops, it will connect women with one another and provide mentoring opportunities to help women be successful in our company and our industry.

I try to maintain a healthy perspective on my career, and to remember that the best way i can have a long-term impact is by taking a personal interest in the success of others.
