Episode notes
Overhead Beats Gross Production
- Overhead percentage matters more than gross production for practice value.
- A $600k practice at 50% overhead can be more profitable and less work than a $1M practice at 70% overhead.
Minimize Core Overhead Categories
- Keep core overhead items minimal and clearly defined (chairs, staff, lab, equipment, basic marketing).
- Justin tracks overhead tightly (he cites ~50.5%) so bad months hurt less and cash flow is more stable.
Early Career Debt And Guaranteed Pay Story
- Justin recalls graduating in 2001 with $150k student debt and early associate pay that extrapolated to ~$50k.
- He negotiated a guaranteed $60k early in his career and later carried small monthly practice and loan payments (~$10k total).
