Our Mission Statement

“TNT Consulting Firm, LLC is a company providing professional medical billing and front office services to small private practices in the Metro Phoenix area. We are an outsourced solution to reducing overhead, increasing reimbursement rates and increasing revenue for physicians and specialists with their own practice.”

TNT Consulting Firm is a family-owned business, originally established in 1996 as Timpson Tax Service.  Founded by Carl Timpson, with the addition of Beth Timpson – Schleeper in 1998, TNT Consulting Firm was formed. We have been providing direction in all facets of business to our medical provider clients including medical billing, budgeting, payroll, accounts payable, accounts receivable, and compliance.  

Sadly, we lost Carl in 2012.  Since then, Beth has continued TNT’s growth, great customer satisfaction, educating and finding new ways to improve services.  She is an expert in medical billing and front office management.  Beth has earned several credentials through the American Academy of Professional Coders (AAPC).

It is this extensive industry and business knowledge that enables us to provide our clients with a wide array of services at affordable rates.

Turnaround on paper insurance claims can be 30, 60, even 90 days or longer, creating serious outstanding receivables for your practice. T & T Consulting Firm provides a time frame of only 21 days from fee tickets to insurance payments.
