Abstract: Rising demand in solo telehealth psychology practices requires balancing growth with limited time, supervision, and financial resources. This anonymized case study examined a U.S.-based solo practice evaluating three staffing models: a practicum student, a postdoctoral fellow, or a licensed psychologist. The objective was to expand client capacity while preserving care quality and financial viability. Using practice records, guidelines, labor data, and supervision requirements, the analysis compared supervision burden, revenue potential, and sustainability across models. Findings showed practicum students had the lowest direct cost but required intensive supervision, limiting overall capacity. Postdoctoral fellows emerged as a sustainable staffing configuration, offering financial feasibility and moderate independence. Licensed psychologists provided autonomy and billing flexibility but carried the highest financial risk. The case suggests staffing choices must weigh financial tradeoffs alongside the owner’s supervision capacity. For resource-constrained solo practitioners, the study offers a framework for testing staffing models before implementation. Aligning staffing strategy with clinical and financial realities enables solo telehealth practices to pursue sustainable growth while supporting workforce development.
