President and CEO

One of my greatest joys is teaching and mentoring people. Sometimes, people come into our industry with no prior collections experience. But through regular teaching and mentoring, they grow rapidly. I really enjoy watching their progress. Watching them challenge themselves further, growing more confident and successful.

As much as I enjoy watching our staff succeed, I also feel great pleasure helping our clients’ businesses succeed. We do this by creating long-term partnerships with them.

When clients tell us, “You guys did a great job, I couldn’t have done it without you,” then I feel proud. That’s when our team met our goal: treat our clients’ accounts receivables as if they were our own.

This all goes back to the cornerstone of our business: integrity.

I believe we should all conduct ourselves with integrity in everything we do. This means debts must be paid. And we must collect them with honesty and compassion.

Liesl Barkley, VP Customer RelationsLiesl Ann Barkley
Vice President of Customer Relations

I’m a people person. I love what I do because I meet new people and create new relationships every day. I also love what I do because I love to sell. So what’s better than doing two of your favorite things all day long?

I’ve been in the credit and collections industry since 1985. When I walk into new businesses, I usually hear the same thing. I hear how they’re tired of being treated like a number by “the other guys.” I see when a vendor doesn’t deliver on what they promised, they can seriously hurt their client’s business. This personally bothers me.

That’s why I care so much about my clients. I do everything I can to make sure they’re happy and satisfied. They trust me with their business and I take this responsibility very seriously.

With everyone at NBF working so well together, our clients easily meet their goals. Only when a client’s happy and successful, do I feel we did our job.

Brenda Shelton, Collections ManagerKay Green
Collections Services Manager

When I joined NBF in 2003, I was impressed by the staff’s genuine friendliness and support. In an industry where you work with debtors, it takes a tight knit team like ours to stay motivated and supportive.

I believe this is one of the main reasons why we consistently beat our collections goals.

What I appreciate most about working for NBF is we support the long-term relationships of our clients and their customers too.

For instance, our collectors understand how we treat debtors reflects on our clients. So it’s important to be respectful, compassionate and honest. Especially when we’re collecting on medical bills.

When we remember we’re all people here to help each other, we all succeed: our company, our clients and their customers.

Kay began managing complex projects while developing a cable company in Sacramento. She was instrumental in creating their customer database, billing and collection procedures. She also staffed and managed the office team and was responsible for the supervision and scheduling of the installation team.

Kay holds a Qualified Manager’s certificate issued by The State of Nevada Department of Business and Industry.

Sarah Walker, Client Services ManagerSarah Walker
Client Services Manager

Back in 1998, I started with NBF as their receptionist. I like being challenged to do and learn new things. So before long, I moved into the accounts receivable (AR) department. From the AR department, I was given the opportunity to work in, and eventually manage, the information technologies function. Recently I have assumed the role as NBF’s Client Services Manager. What I like most about this position is its unpredictability. Clients call daily with new challenges to their business. I take their issues personally because delays could impact their cash flow.

The people I work with at NBF are definitely my second family. We really care about each other. The mentors here have so many years of experience and are always willing to share it.

So no matter how long you’ve been here, you end up getting more than professional advice. Many times you learn valuable life lessons.

Things to know about Sarah
Sarah has transitioned from information technology within NBF to now managing our client services department. As our Client Services Manager, she works with NBF clients as well as the Vice President of Customer Relations. Never one to rest on her laurels, Sarah often looks for new ways to help us run more smoothly and efficiently.

Sarah enjoys spending time with her grandchildren.

Sarah Walker, Client Services ManagerKim Miller Lundquist
Information Technologies and Mail Room Manager

Most people think of Information Technologies (IT) Departments as an area that consists of maintaining equipment and networking. In our department here at NBF we do much more than what most expect. A key part is customer service and working one on one with clients. We assist them in creating custom electronic files and custom reports. One of my top priorities is to ensure what we do assists the clients in the most efficient way possible. Troubleshooting, no matter how challenging, for clients provides me a great sense of accomplishment. I enjoy the interaction with NBF employees and our clients.

The department faces many challenges due to the ever changing IT landscape and is an integral department within NBF. IT assists with keeping other departments running smoothly.
