About Mar

With over 20 years of senior Medical Affairs leadership across top-tier pharmaceutical and biotechnology companies, I bring strategic depth and hands-on execution to every engagement.

I specialize in building and transforming Medical Affairs functions from the ground up: designing medical plans, leading go-to-market strategies, developing MSL teams, and delivering scientific communications that drive measurable impact at the intersection of science and business.

My expertise spans oncology and hematological malignancies, rare diseases, and specialty care, with a pan-European track record managing product launchesand training sales reps, Medical Advisors, Medical Directors and MSLs across markets.

A core pillar of my work is Scientific Communications — from strategy to execution. I support the development and review of promotional and non-promotional materials, market access dossiers, medical information content, infographics, clinical research documentation, and patient-facing resources. I ensure scientific accuracy, regulatory compliance, and compelling storytelling across all formats and audiences.

What sets me apart today is the integration of Artificial Intelligence into Medical Affairs — helping organizations leverage AI tools to accelerate evidence generation, optimize field medical strategy, and future-proof their medical organizations.

I work with:

Biotech and startups building their Medical Affairs function for the first time
Global pharma companies needing senior expertise for specific projects
CROs, consultancies, and agencies requiring specialized oncology and medical strategy input
International companies entering or expanding in the Spanish and European markets
Creative and medical communication agencies needing senior scientific oversight

Whether you need a strategic advisor, a medical plan architect, scientific content reviewed, or an MSL excellence program — I deliver senior-level thinking with the agility of an independent consultant.
