CEO

GUILLAUME LE GAVRIAN

With 22 years of international experience in the glass industry I strive to maintain Vetrotech’s focus on excellence in customer service, manufacture and development of fully-compliant solutions, and sustainability. My goal is to create the best possible customer experience to earn your trust as a reliable partner.

I joined the Vetrotech family in 2015 as CEO. Leading such an international business with such a wealth of intercultural relationships is a great professional experience. With the strong technical expertise and customer focus of our teams we can be sure to accomplish our shared mission of protecting life and property all around the world together with you.

I consider myself a multi-national person and have lived in six different countries. In order to keep up with the energy this job requires I run three times a week. I am also a keen musician: I play the guitar and sing whenever I can to relax and have fun with my family and friends.

CFO

NICOLAS DUHEM

I joined the Saint-Gobain group in 1985 and gained several years of experience in accounting, corporate finance, internal controlling and merger and acquisition. As a result of the acquisition and integration project of Vetrotech in 1995 I became CFO of the newly created Swiss Vetrotech Saint-Gobain. I am proud to have contributed from the outset to the development and growth of what is now the international benchmark in the fire-resistant and security glass business.

To work for Vetrotech Saint-Gobain continues to be an extraordinary adventure – thanks to our drive for change, our exceptional products, our experienced teams and the loyalty of our customers to achieve our common mission of making this world a safer place.

I am dual French-Swiss citizen and have been living in Switzerland for over 20 years. In winter I like to snowboard and in summer I go hiking in the mountains. Renovating my chalet in the canton of Vaud in Switzerland – built over 220 years ago – is my other passion and is my personal contribution to a sustainable habitat.

MARKETING & SALES DIRECTOR

KIRK RATZEL

My first experience with Vetrotech Saint-Gobain was as a customer. I am an architect by profession but have spent most of my professional career in the building products industry. I joined the company back in 1993, and was fortunate to work under the company founders who passed on to me their passion of developing and bringing to market fully transparent, fire-resistant safety glass.

What I like most about this business is that every day, together with our customers and partners, we contribute to a safer and more secure world.

I am a dual American-Swiss national but consider myself first and foremost a “citizen of the world”. Over the years, I have lived and worked in five different countries and have acquired much experience in international market development and sales. When I find some free time, I follow my other passion of riding and restoring classic motorcycles.

SALES DIRECTOR EUROPE

PAUL GOUDEAU

I am a French National with British roots, married to a wife of Chinese origin whom I met during my international business school years, and I am the happy father of 2 teenage girls.

After obtaining my MBA, I began my professional career in the petrochemical sector in Thailand before joining the glass business of Saint-Gobain in September 2000.

There, I have had various experiences: managed organizational projects in Italy, Spain & China, headed the Middle East & Asia export Area, directed the Sales & Marketing department of a newly opened float company in Egypt, before taking over the general management of the Japanese subsidiary. Between 2012 and 2018, I was the General Manager of Exprover, Saint-Gobain's glass exports business unit, then joined Vidrio Andino in Colombia as Managing Director in late 2018.

Heading today the European business of Vetrotech Saint-Gobain is a wonderful new step for me. I join a team of high caliber professionals alongside whom I wish to bring those soon 20 years’ experience with architectural projects and glass to live up to Vetrotech’s motto fully. We thrive advising and supporting every partner and stakeholder on bringing the proper glass solutions to safety design requirements whether burglar, attack or fire protection is concerned.

I have a great taste for architectural works but also natural landscapes that I love to photograph when travelling or mountain hiking with my camera. I love cooking for my family and friends, eating French cheese and tasting good wines as well! Passionate about Rugby, I have practiced it for 20 years. Lately I have discovered motorcycling, a new way to do one of my preferred activities: travelling the world & meeting new people.

OPERATIONS DIRECTOR

GUIDO PLUM

I started my career in glass back in 1990 as a process engineer in the German subsidiary of Saint-Gobain in Aachen. In 1998, together with the founders of Vetrotech, I supported the development of the highly innovative Contraflam technology.

As Managing Director of the production site Vetrotech Kinon Aachen and Business Manager Protect I was for many years in charge of producing and developing security glass products that comply with the highest life-safety industry standards while also producing fire-resistant glass for Vetrotech in Aachen. I’m now carrying this drive into my new responsibility as Operations Director overseeing our processing and manufacturing activities.

The commitment of all our employees and the loyalty of our customers help me to focus on optimizing our production processes, developing new products to drive innovation and deliver our solutions in the best final quality possible.

I am German but see myself as a multicultural citizen. I have a passion for cycling and enjoy spending some quality time out in nature with my family and friends.

HUMAN RESOURCES DIRECTOR

TINA BÜRGI RAVENNE

Shortly after my law studies at the university of Berne and Bologna, I started working in construction-related industries before I joined the Vetrotech family in 2015. I speak four languages and am pleased to leverage this advantage in our multi-cultural organization.

I am Swiss, married to a French citizen and have lived in Italy for a while before returning to Switzerland. I consider myself a real bookworm – I read two to three books a week – and love having a nice meal with friends. Now that I’m a mum of twins, I’ve cut back on my sporting passions of basketball and lindy-hop as well as rock’n’roll dancing to enjoy quality time with my own family.
