Who We Are

About Affinity Clinical Group

Affinity Clinical Group provides embedded senior clinical science & development leadership to emerging biotech and pharma teams when clarity, judgment, and execution matter most.  Founded by James Winnberg, MS, Affinity brings 20+ years of oncology and sponsor-side development leadership — including senior roles at global pharma and close partnership with biotech teams across early and late-stage programs.


When program complexity demands broader expertise, Affinity integrates select senior collaborators with deep sponsor-side experience — extending leadership capacity without unnecessary layers.

Why Affinity Was Founded

Affinity Clinical Group was founded to support emerging biotech and pharma teams at inflection points—when complexity rises, stakes increase, and experienced clinical leadership becomes essential.

We step in to provide clarity, alignment, and decisive direction—without adding unnecessary layers or noise.

Our Stewardship Approach

Stewardship at Affinity means leading from within—with clear accountability for decision quality and program direction. We engage selectively, prioritizing experienced judgment over activity volume and bringing disciplined leadership at moments that carry lasting impact.

Clarity begins with the right conversation.
