What do you attribute your success to?
I believe that my overall success is based off my hard work ethic and strong faith in God. Psychology is my educational background. My faith in God and my innate ability to read and understand how to operate around diverse professional cultures comes into play and contributes to my success. I thrive on learning and developing my interpersonal skills while expanding knowledge in the renewable energy field.
What’s the best career advice you’ve ever received?
The best career advice I ever received is to maintain a sense of humor and practice open/ honest transparency in every situation. Stay flexible and open to achieve success even if you find yourself taking a different route to get there.
What advice would you give to young women entering your industry?
We don't have as many women in the solar engineering & construction field as I would like to see. Our industry is constantly evolving and there is so much to learn and develop as a solid career. I encourage the female students to reach out to our company and request to take on an internship for the summer. We have successfully hired students for full-time positions as engineers who are still valued Project Engineers, today. This industry continues to streamline ways of conserving energy, and it's a fantastic field. As long as we have the sun - solar is here to stay.
What are the biggest challenges or opportunities in your field right now?
We're in the business of saving School Districts and City Entities money. There are two particular challenges that I face when successfully commissioning my client with permission to operate. The first is the Utility, itself. The utility doesn't appreciate our service since we essentially replace their service in order to save the client energy via system size and megawatts. The other challenge is the state of California. From when I began in this field to the present, a lot has changed and California has increasingly gotten more difficult to comply with all the state regulations.
What values are most important to you in your work and personal life?
My Christian faith is the most important part of my life. I attribute all of my works to God and I drive my successes by my morals, christian values and hard work. I put a lot of pressure on myself (no one has to do it for me...) I thrive on a good challenge whether it's a new task/project or a challenging client. My psychology background enables me to be good listener, to take in constructive critics and grow from it, not dwell. I'm pragmatic, by nature, so I know how to be realistic and draw clear conclusions in a timely manner. All of these things are carried over to my personal/family life because I do know how to balance. What you see is what you get, personally and professionally. Outside of my office, I love the outdoors: snow skiing, walking, gardening, camping when I have time, I love to create and play around with crafting. Soon, I will be a grandmother so that will be my next adventure.
