What inspired you to start your company, and what has shaped your journey woman business owner in CRE?

The Stevens Group was founded by my parents, Mark and Debra Stevens, in 1980, and I joined the firm in 2013. My mother had a remarkable career in commercial real estate and showed me firsthand what was possible for a woman in the industry, while my father was an equally important mentor and supporter. Since Debra’s passing last year, carrying forward what they built has taken on added meaning. I am proud of our history and committed to positioning The Stevens Group for the future while preserving the integrity, reputation, and client focus that define us.

What are you most proud of about the company you’ve built? 

I am most proud of the trust we have earned and the long-standing relationships we have built with clients over more than four decades. Our size and independence allow us to stay closely involved, be responsive, and give objective advice. I also value that we have continued to evolve and stay current while remaining true to how we do business.

Celebrating 15 years as a certified women business enterprise is another milestone I am especially proud of.

What are you most excited about for your company and its future? 

I am excited to continue expanding the ways we support clients as their real estate needs become more complex. We have the advantage of being nimble, experienced, and highly personal in our approach, while our ITRA Global affiliation gives clients broader reach when they need it. I see the next chapter as thoughtful growth, interesting assignments, and continuing to strengthen our reputation as a trusted advisor to corporate occupiers.

What does being a woman-owned business mean to you, and what perspective would you share with women considering starting a business of their own? 

Being a woman-owned business is meaningful to me because it reflects how far opportunities for women in commercial real estate have come. CRE Brokerage is a demanding career, but I believe women can build successful businesses and careers in this industry without having to choose between professional growth and the other priorities in their lives. My advice is to seek out strong mentors and advisors, trust your expertise and create a culture that values high performance and flexibility. The right environment can make a meaningful difference in sustaining a rewarding career over time.
