10 Years of Dedication, Expertise, and Team Spirit!
On June 1, 2016, we welcomed our colleague, Markus Dingeldein, to our company as a design engineer.
For ten years now, he has been bringing his expertise, experience, and dedication to every project. With his meticulous approach, technical understanding, and high standards for quality, he makes a valuable contribution to our company day after day. But his importance to our team cannot be measured solely by drawings, designs, or projects. It is also his reliability, helpfulness, and loyalty that make him a valued colleague.
Ten years with the company stand for consistency, trust, and mutual appreciation.

Dear Markus, we are proud and grateful to have you on our team for so many years, and we thank you from the bottom of our hearts for your tireless dedication, your reliability, and the many valuable contributions you bring to the Arnold Group.

10 years of dedication, precision and team spirit
A few days ago, we had the pleasure of celebrating a very special anniversary:
Wolfgang Hagner has been part of the Arnold Group since 1 May 2016 – and has thus been an indispensable pillar of our machining team for 10 years now.
As a machining technician specialising in turning, Wolfgang impresses day in, day out with his exceptional precision, extensive expertise and impressive commitment to quality. What in production often looks at first glance to be ‘merely’ technical work is, in reality, true craftsmanship – and it is precisely this that Wolfgang has been living out with total passion for a decade.

We particularly value not only his technical expertise, but also his reliability, his helpfulness and his long-standing loyalty. People like him leave a lasting mark on a company: through experience, loyalty and a willingness to always take on responsibility.
10 years of service means:
10 years of dedication.
10 years of trust.
10 years of shared growth.
And countless hours spent contributing to the success of our company with the utmost care and commitment. We would like to say a heartfelt thank you today for this long-standing loyalty and daily dedication. We are proud to have Wolfgang on our team and look forward to many more years together.
Congratulations on your 10th anniversary, Wolfgang, and thank you very much for everything you do for the Arnold Group!
