At Sentinel Spark, our mission is clear: help clinical trials reach and enroll the right patients.

We are a full-service digital marketing partner dedicated exclusively to clinical trial patient recruitment. We work with research sites, sponsors, and CROs to design, launch, and manage high-performing recruitment campaigns that connect eligible patients with the studies that need them.

From strategy to execution, we manage every stage of the recruitment funnel — including targeted advertising, creative development, landing pages, prescreening flows, tracking, and ongoing optimization. Our approach combines data-driven marketing with a deep understanding of the clinical research landscape to improve enrollment timelines and lead quality.
