Where do you live, and where do your companies operate?

My office is near Frankfurt, not far from the international airport and close to the largest and most important wine growing region in Germany. Here the famous Riesling is produced. HPC has been serving customers in nearly all European countries for many years with > 40 branches and > 650 employees.  We offer a wide range of services with our branches in Germany, Italy, France, Poland, Spain, Austria, Hungary and Kosovo. Often together with the partners of Inogen Alliance we have successfully realized joint projects in all 28 countries of Europe and in many countries across Africa, Asia and the Americas.  

What is your background and role?

I am a hydrogeologist and have a PhD in geophysics. I have been doing the business as a consultant for about 15 years, 10 of them at HPC. For 20 years I worked as an EHS manager in the chemical specialties industry. During this time I have been responsible for M&A projects worldwide and have provided technical and financial support for many contaminated sites and landfills. During this time with many upheavals and mergers I was able to work with most of the well known consultant companies worldwide. In the first years at HPC AG I managed several international projects, especially in Kosovo, Albania, Israel, Vietnam and Cuba. I am managing the Frankfurt office and have a very international team of 30 employees. I am in the executive board of HPC and very well connected in the HPC group. 

How long have you been a part of Inogen Alliance and what value does Inogen bring to you as a member?

I have known Inogen Alliance since it was founded. My contacts to Inogen Alliance have existed for almost 30 years, of which about 20 years as a customer, i.e. quasi on the other side of the table, and 10 years as a partner. HPC, as one of the 3 founding members, brings itself into the Inogen Alliance network as a reliable partner and benefits from its worldwide presence. In terms of customers, through the Alliance family, we can offer many competences developed in the partner network and especially meet the needs of multinational clients. I like that the Inogen Alliance family is customer-centric and practices common values. The diversity in the Alliance ensures a continuous development of services and values, which in turn is not only directly expressed in good business figures, but also represents an added value for the individual employees and companies. The always forward looking development approach and the diverse cultural interactions are important aspects of working together, not only in the Inogen Alliance family, but also within the HPC Group.
