One face,

The founder’s story—and the values that shape MediQuasar.
Katarzyna Zofia Chrusciel: Founder of MediQuasar
Dr Chrusciel began her career in HSE, quality and environmental fields, gaining first-hand experience of multidisciplinary collaboration and the impact of clear, measurable processes. In 2011, she shifted her focus to medical devices—seeing compliance not as a constraint, but as a catalyst for innovation and patient safety.
She has held senior operational and management roles—including Corporate Director for Quality Management & Regulatory Affairs (Europe), Principal Consultant (Global) and MDR Project Leader (Europe)—leading regulatory teams, shaping market access strategies and delivering remediation programmes across Europe and internationally.
Since 2021, she has supported MDR/IVDR implementation as an HAS consultant. As an outsourced PRRC and consultant, she works alongside organisations to build ISO 13485 quality systems, strengthen technical documentation, manage clinical and performance evaluation, and ensure robust post-market surveillance and vigilance.
With a strong interest in continuous learning and sustainability, she champions projects where compliance enables growth: leaner processes, clearer metrics, transparent engagement with notified bodies and internal capability building—helping organisations become more autonomous, resilient and faster to execute
