This document discusses a physician's practice transitioning from a traditional fee-for-service model to a direct primary care model. It provides details on the practice's patient numbers, staffing levels, sources of income, and goals at different stages of the transition. The physician reflects on underestimating how many existing patients would convert initially, experiencing diminished cash flow as a result, and the importance of partnering early with benefits experts. Advice is given to assume only 7-10% of an existing practice will initially make the change, plan for cash flow needs for 6-12 months, prioritize education over marketing, and implement good technology and communication tools with limited staff.
