Challenge
How do you
turn an evolving diagnostics platform into a scalable brand experience?
As Endless Health expanded its diagnostics capabilities, Endless Dx grew from a loosely defined B2B offering into a platform spanning at-home collection, lab testing, patient results, and partner programs. But the business was evolving as quickly as we were designing it—the product, audience, and story were all moving at once.
Role
As Lead Brand Designer from 2023–2026, I shaped Endless Dx across brand identity, art direction, web, product communication, packaging, motion, and experiential applications.
Precision without coldness. Technical information without intimidation. I built the system around one principle: every touchpoint should help someone understand what is happening, what matters, and what to do next.
I worked across leadership, product, marketing, operations, support, engineering, manufacturing partners, and external collaborators, translating shifting requirements into a coherent system the company could use, ship, and scale.

Brand System: Developed a distinct but connected expression for Endless Dx, including its identity, typography, teal-led color system, data language, and applications across digital and physical touchpoints.
Web Experience: Turned a complex diagnostic service into a clear web narrative and created visual systems for biomarkers, health ranges, longitudinal trends, registration, and patient results.
Physical Experience: Designed collection kits, packaging, IFUs, and return touchpoints that guided users through an unfamiliar medical process while balancing clarity, manufacturing, protection, shipping, and white-label requirements.
Cross-functional Delivery: Worked from incomplete briefs and evolving product requirements, aligning stakeholder needs and carrying decisions through design, production, testing, and implementation.
