History & Values

Where we come from

Thomas H. Althoff has been instrumental in shaping the German hotel industry for more than 20 years, an industry that he first entered when he was little more than 20 years of age. He has become a truly recognised and very reliable personality to his companions and business partners, undoubtedly representing one of Germany’s key leaders in the hospitality industry.


Thomas H. Althoff and his wife, Elke Diefenbach-Althoff, started the Cologne-based business known today as ALTHOFF HOTELS in 1984 with the Hotel Regent International, Cologne. Since then, the group has grown to a total of 15 hotels comprising 1,491 guest rooms in four countries. Identifying and passionately pursuing the right opportunities led to the group’s successful expansion based on a solid foundation. Driven by ambition and perfectionism, Thomas H. Althoff has created one of Europe’s finest luxury hotel brands – the ALTHOFF Hotel Collection – today comprising seven precious hotels in Germany, France and the United Kingdom. Building on this platform, he introduced the first class AMERON brand in 2009, currently with eight upscale business hotels in Germany and Switzerland. The takeover of the operation of the converted Schlosshotel Lerbach in 1992, previously owned by the von Siemens family, marked the entry into the luxury segment.

Eight years later, the group also assumed the management of the nearby Grandhotel Schloss Bensberg, which constitutes one of the most prestigious hotels in Germany, if not Europe. In light of the constant desire to further develop, the significant achievements to date and the solid financial performance over the years, it is only a natural consequence for Thomas H. Althoff to pursue expansion. “We aim to considerably increase our presence throughout Europe - however not at all cost. Each new property will be the result of a careful and sensible analysis, demonstrating that Althoff Hotels as the operator will add value for both the investor and the guest”. Longevity and reliability are important to Thomas H. Althoff, who pursues growth sensibly and feels a strong commitment both towards his guests and his business partners.

Architecture & Design

The main focus is placed on exceptional architecture in combination with sophisticated design. Every single hotel has its own style, according to the pursuit of individuality and personality.


Whether festivities or pleasure trips: service is written with a capital S. This basic principle is carried by staff who actually “live” the luxury hotel business and puts the guests' satisfaction in the centre of all of their actions.

Culinary Delights

Each hotel is characterized by exceptional and multifaceted gastronomy concepts that are amongst the best in their region and beyond. No other German hotel group has been awarded such a high amount of Michelin stars and Gault-Millau points.
