Who we are. What drives us.
/Our Story
For over two decades in practice
2020
Phase 01
Lo
The Founding.
BERTELPARTNER GmbH is entered into the commercial register in Leverkusen.
Owner-managed, without software licenses, without commissions from certification bodies, without Big Four reporting structures. The goal: deliver advisory, audit and training for management systems the way we, as practitioners, always wished it had been delivered to us — committed, pragmatic, with fixed scope and fixed price.
2024/ 2025
Phase 02
Lo
The Build-Up.
From individual engagement to established partner of leading industrial clients.
The portfolio grows across six industries — automotive, rail, aerospace, energy, IT services and public sector. More than 120 clients served, from 10-employee SMEs to listed corporate groups. Over 1,200 audits per year in 30 countries. 100% first-time-pass rate for engagements we support end-to-end.
