What do you attribute your success to?
Someone once told me that I was resilient and diligent, and I think that's true. I'm not afraid of anything. My mom told me that if you don't ask, the answer's always no, so I operate on that principle. They say when you go into a room, you gotta act like God sent you into that room to do business, so I kind of operate on that level - with confidence and persistence. I think my mom also raised me to be tough, which has served me well in this industry.
What’s the best career advice you’ve ever received?
The best career advice I’ve ever received is to not be afraid of change, because growth and new opportunities often come from stepping outside of your comfort zone.
What advice would you give to young women entering your industry?
I told a young girl who started with our company to not get caught up in the attention that men would give her. I told her to stay steady and be professional. If you don't stay steady, persistent, and keep your head up, this town and this industry will just chew you up and spit you out - I mean, it's just the truth. It's very hard for women because some women have kind of ruined a woman's name in the industry, and I think it's very important to just remain professional, stick to your job, and also know what you're selling. As a woman in this industry, know your value and be the value.
What are the biggest challenges or opportunities in your field right now?
Some of the biggest challenges in the field are a lot of unanswered phone calls - a lot of phone calls don't get returned. There's also just the competition. And honestly, there's not enough time in the day. In my position, I really don't get a break. It's hard for a woman in this industry, and there are not enough women in the field.
What values are most important to you in your work and personal life?
One of my values is to say what I mean and do what I say. I always answer my phone, and when I tell my customer that I'm going to take care of them, I take care of them. I also treat my company's money like it's my money. I take a lot of pride in being truthful and honest in everything I do. I don't promise something that I can't give people just to earn work. I want people to respect me for the job that I do, not just for other reasons.
