A single optometry practice is a valuable clinical asset. A network of five, operating under shared infrastructure with centralized billing and standardized clinical protocols, is an institutional-grade platform commanding 9.0–12.0x EBITDA at exit. Lumina structures the capital that builds the network.
Initialize Practice Equity AssessmentThe DSO (Dental/Doctor Service Organization) and OSO (Optometry Service Organization) structures are management service organizations — not clinical entities. Lumina Medical Capital structures capital for both the operating MSO and the professional corporation network it supports, ensuring every capital instrument is placed in the legally appropriate entity tier.
Each layer of the DSO/OSO capital stack serves a distinct purpose — and each carries different risk, rate, and covenant characteristics that must be engineered in concert.
Each location threshold unlocks a new capital instrument, a new lender relationship tier, and a new EBITDA multiple at exit. Building toward the right milestone is as important as the capital structure at each stage.
Two to three locations establishes the MSO operational model — centralized scheduling, shared billing, unified supply agreements — but EBITDA ($1.2M–$2.2M) is still below institutional interest thresholds. Capital at this stage: SBA 7(a) senior debt with seller carry, personal guarantee still required, DSCR covenant of 1.25x–1.35x. Exit multiple: 5.5–7.5x.
At four to six locations and $2.2M–$4.5M EBITDA, the platform enters institutional PE visibility range. Acquisition revolvers become available from regional banks. Seller note participation from add-on targets becomes standard. Centralized billing must be operational and demonstrating DSO improvement. Exit multiple: 7.5–9.5x. This is the optimal recapitalization window.
Seven-plus locations with $4.5M+ EBITDA qualifies for true institutional senior debt: non-SBA leveraged buyout structures, limited or non-recourse guarantees, and formal PE partnership interest. At this stage the MSO itself becomes acquirable by a larger DSO operator at 10.0–13.0x. Capital strategy pivots from growth to exit optimization — covenant management, EBITDA normalization, and management depth documentation.
Sponsors routinely underestimate integration costs. Per-location integration runs $180K–$320K when fully accounted — and underfunded integration destroys the EBITDA they paid to acquire.
Migrating from legacy EHR (Revolution EHR, Crystal PM, Compumed) to a unified platform costs $15,000–$38,000 per location including data migration, staff retraining, and parallel-run period. A 5-location integration requires a dedicated $75K–$190K EHR capital tranche.
Exterior signage, interior branding, uniform programs, and patient communication rebranding runs $12,000–$28,000 per location. Brand consistency signals operational maturity to buyers and reduces perceived transition risk — directly supporting multiple expansion at exit.
Transitioning acquired practices from independent frame and contact lens purchasing to a centralized MSO vendor agreement typically saves 8–14% on COGS — but requires 60–90 days of parallel inventory management and vendor contract renegotiation funded by working capital.
Clinical protocol standardization, staff cross-training, and management reporting onboarding requires an average of 120 hours of dedicated management time and $8,000–$18,000 per location in consulting and training costs. Underfunding this phase is the leading cause of post-acquisition EBITDA degradation.
Once your DSO/OSO platform reaches institutional scale, the exit decision — PE recapitalization vs. independent strategic sale — determines how much of the multiple accrues to you. Explore the full comparison framework.
