About me

As a management consultant and interim manager, I am specialized in helping medium and large companies to optimize their sales and customer service operations.

With more than 20 years of professional experience as consultant, interim manager and line manager in renowned international companies, I possess the required seniority and sovereignty to manage complex and time critical projects, also in international context.

Professional experience, deep industry knowledge, analytical skills, pragmatism, customer orientation and implementation strengths are the key pillars of my successful working style.

As your partner, I will help you with the assessment of the as-is situation, the conception and evaluation of strategic options and - most importantly - with the timely implementation of the defined measures and strategies. My consulting approach is highly result-focused, and my working style based on closed partnership with my clients.
