01Physician relationship and panel size
MD2 publicly describes a 50-family-per-physician model, defining access through an ultra-small physician-family panel.
PrimaryMD also limits membership intentionally. Its physician remains central, while a wellness expert and care coordinator help close loops between visits.
02Prevention, diagnostics, and interpretation
PrimaryMD is explicit about the diagnostic layer: broad biomarkers, DEXA, VO₂ max, resting metabolic rate, wearable integration, coaching, and recurring clinical review.
The point is not more testing for its own sake. It is having one accountable team interpret results in context and keep the plan current.
03Adult-focused care or family care
MD2's public model is family-centered. PrimaryMD is designed for adults who want their own primary care and prevention plan coordinated in one clinical home.
PrimaryMD’s adults-only model is designed for people seeking an adult clinical home that connects everyday primary care with prevention and health optimization.
04Travel, urgent needs, and reach
PrimaryMD's footprint is more concentrated, with urgent support after hours or while traveling available through its Sollis Health relationship under applicable terms.
PrimaryMD extends urgent support through Sollis Health under applicable terms, while its own team keeps responsibility for the long-term plan and follow-through.
