Alexander Hahn


Alexander Hahn revolutionised the lighting industry with the founding of the Deutsche Lichtmiete®: an Oldenburg-based company, offering business clients rental models, which cover all lighting services and increasingly address sustainability issues in the industry.

His excellent business sense and sensitivity to environmental issues have brought Alexander Hahn together with the light manufacturer, HOLY TRINITY® in recent years. He was immediately fascinated by the ideas and mission at HOLY TRINITY® and sealed the deal for acquisition of the Dresden-based company in 2016. Since then, Alexander Hahn has been steadily promoting the growth of Deutsche Lichtmiete’s affiliate, HOLY TRINITY®, and ensuring continuous progress on the road towards sustainability in lighting.

Jennifer Lachky

Head of Marketing & Branch Manager – the tough mudder

True to the motto “better late than never,” Jennifer Lachky discovered her passion for Marketing only after completing her first occupational training. Now she is fully immersed in the world of Marketing and, as the Marketing Director at HOLY TRINITY®, is responsible for the development of new advertising strategies and marketing campaigns, as well as keeping HOLY TRINITY’s social media channels updated with new content. So that she can pursue her love of Marketing even outside of the office, Jennifer also works as a lecturer for the IHK, where she can pass on her knowledge and passion to up-and-coming marketing talents.

Jennifer Lachky has already demonstrated her team mentality and perseverance at the Tough Mudder. The 18-kilometer obstacle course – predominantly through mud – would push any participant to the limit, but the cold beer at the end makes it all worthwhile.

Stefan Melzig

Construction & Production – the motorcycle aficionado, with 5 bikes of his own

Stefan Melzig is responsible for ensuring that our crazy ideas can be realised. As an engineer, Stefan Melzig develops prototypes for new luminaires and ensures that models can eventually be made into production-ready products – from the technical drawing to the finished product.

In the office, Stefan is a calming presence in every situation. He also handles all the manual work around the office. Whether it’s fixing the coffee machine or assembling furniture, Stefan makes sure that everything is running smoothly in the office. After work, Stefan prefers tinkering with his own machines. A passionate motorcyclist, he has five bikes in his garage.

Justine Büschel

Marketing Assistant – the soccer player

Justine Büschel just wanted to do an internship during the semester break to help her decide what she wants to do after her bachelor’s degree. But she enjoyed her time at HOLY TRINITY® so much, that she’s been helping Jennifer Lachky keep a cool head in the office as Marketing Assistant for over two years now. In addition to her master studies in Corporate Media, Justine authors new blog entries and texts for press relations, and supports Jennifer in marketing campaigns.

Since Justine was little, she has shared her father’s enthusiasm for soccer. For eight years she has been kicking as a member of the women’s team in her hometown.

Melanie O´Neill

Trainee – the opera aficionado

During her Bachelor studies in Music at Boston University, Melanie O’Neill completed a semester abroad in Dresden in the spring of 2013 – a semester which had a lasting impact on her future. After working as Assistant to the Artistic and Executive Directors at the Washington National Opera in Washington D.C. for several years, Melanie found that the time was ripe for change. Without much further ado she picked up and moved back to Dresden. At HOLY TRINITY®, Melanie began as an intern and later decided to begin an apprenticeship in Marketing Communications. What she learns from her studies is then applied directly here in the office.

Even though professionally Melanie has left music for the time being, opera is still her number one passion. She makes a point to see as many operas as possible- in different countries, different languages, with different singers, and in different productions. One of the things she loves most about the opera is that you can never see the same show twice.
