Kate is the Vice President of the Academy of Dental CPAs, a member of the Academy of Dental Management Consultants, and the Speaking Consulting Network.

Debra Lane, CPA, Senior Tax Manager

Debra Lane, Senior Tax Manager at Willeford Group, takes great pride in helping her clients achieve the business profitability that they rightfully deserve.  Above and beyond the average accountant, she is the gold standard in providing highly individualized and comprehensive financial business analysis and services for her dental clients.

What does Debra enjoy most about her work? “It is tremendously rewarding using my unique knowledge of dental business accounting and working with my clients to help them exceed their financial goals.”

“So often I have dentists come to me with serious cash flow issues and practice management concerns. I understand that most dentists simply don’t have the essential business training, so I help educate my clients and provide them with solutions that can yield dramatic results. That, to me, is truly gratifying.”

Debra Lane has been providing tax, consulting, and planning services for dentists since 1991. Debra’s many years of experience include work in the tax department of the national CPA firm, Price Waterhouse, and Lane and Associates. She has lectured and authored articles on tax and accounting, specific to dentists and their practices.

Her advanced training includes a Master’s degree in taxation from the University of Denver, as well as a BA degree in Business Administration, with an emphasis in accounting, from California State University in Fullerton. Debra Lane is a member of the Academy of Dental CPAs, (ADCPA), American Institute of CPAs, (AICPA), and the Colorado Society of CPAs, (COCPA).

Debra and her husband, Bob, live in Parker where they enjoy property renovations and woodturning.
