Who We Are

Cellular Billing Consultants was founded by Mindy Prowler in 1998. Prior to starting her own consulting firm, Ms. Prowler was the General Manager for a number of cellular companies overseeing their customer service, sales and billing departments. Before entering the cellular industry, Ms. Prowler was the Controller for Financial Management Advisors in Beverly Hills and was also with Arthur Young & Company in Los Angeles.

CBC has been regular contributors to CBS affiliate station KNX/KFWB’s ‘Money 101’ advising their listeners on managing their cellular costs. We have been featured in Bloomberg Businessweek, the Los Angeles Times and other outlets sharing best practices with their readers as well as assisting law enforcement by providing expert testimony concerning cellular usage.

With over twenty years in the cellular industry we have the experience and knowledge to save you money on your wireless and data bills. And just as important, we believe in providing outstanding customer service.


Working with Mindy as our Cellular Billing Consultant over the years has been an absolute joy. She is so easy to work with and has saved us on errors and money. The ROI working with Mindy has been tens of thousands of dollars over the years. I would highly recommend her services.”

“I have been using Cellular Billing Consultants for several years now and I can only say great things about them. At first I thought I could deal with my cell phone bills. I was wrong, it has paid for itself many times over and continues to do so.”

You are the best! You handled a difficult situation with Sprint and made sure we received all that was promised, which was substantial. Keep it up.”
