Who I work with

As a dental CPA, I work with dental practice owners and dentists who are looking to grow an existing practice, or start or buy a new one. I love helping my clients grow and count it a privilege to be part of their success.

My specialty

I have dedicated the past decade of my life to helping dental practice owners grow their businesses. The dental benchmarking, financial analysis, and corporate and income tax planning and strategies I provide helps dentists thrive throughout the life cycle of their practice. Through frequent benchmarking reviews and close contact, I help practice owners understand the financial health of their practices, capitalize on tax saving opportunities and achieve their goals through transitions, increased collections or investments in their practices.
