What led to your current leadership position?
I became president of Mark One Electric in 1994, after 20 years of experience in daily operations and strategy, when my parents retired. They started the business in 1974 servicing small business, commercial and industrial accounts. We quickly developed a reputation as a company that could handle the most difficult projects, and we soon expanded into industrial facilities throughout the U.S. As president, my job became focused on growth and preparing for the future.

Whas has been the greatest challenge you've faced in your role?
My biggest challenge has been being a female in a male-dominated industry. I found out quickly that my employees knew of my commitment to and passion for the company, as most of them had worked alongside me for 20 years. So, although there have been challenges along the way, it seems very natural now.

What prepared you most for this position?
A combination of family support and personal traits. I had wonderful parents who had a vision for the company. I have excellent family relationships—including with three brothers who serve as vice presidents at Mark One—that I can rely on in good times as well as challenging ones. Personally,  demonstrating persistence and a willingness to adapt have been invaluable.

What has been your greatest success?
As of 2021, I’ve been leading Mark One for 27 years. Most companies don’t last that long. I attribute that to effective leadership, strong business relationships and dedicated employees.

What advice do you have for women who aspire to become leaders in their fields?
Always pursue your goals. Be persistent.

What quality do you most admire in a woman leader?
Home, food, good company

What is your leadership style?
Hands-on, very direct
