Dear clients and partners,
We are pleased to inform you today about an important and positive development:
Goldstein Consulting is becoming part of the Auren Group.
After many successful years in tax consulting and auditing, I have decided to shape the future of our firm together with the highly successful Auren KG. This step is part of our succession plan and, at the same time, a conscious decision to ensure that Goldstein Consulting continues to develop in a demanding and high-quality environment for the long term.
The market for tax consulting and auditing has changed significantly in recent years, presenting many medium-sized firms with new challenges. Through our cooperation with the dynamic and rapidly growing Auren KG, I see a unique opportunity to meet these challenges even more effectively in the future – to the benefit of our clients as well as our team.
This merger represents a true partnership at eye level, built on shared values, high quality standards, and a clear focus on personal, reliable, and sustainable consulting. Together, we are combining our strengths and expanding our expertise to support you even more comprehensively in the future.
Lothar Schulz, Managing Partner of Auren, sums it up perfectly:
“We are very pleased about the merger between Auren and Goldstein Consulting in Berlin. Two companies with a clear focus on the holistic consulting of medium-sized enterprises, a shared vision for the future, and common values. The colleagues from Goldstein Consulting bring many years of experience in tax consulting and auditing – particularly in the environment of dynamically growing companies. For Auren, this represents a valuable addition: we combine the competence and structure of a nationwide consulting firm with an in-depth understanding of the needs of medium-sized businesses and, in particular, the start-up scene.”
What does this mean for you as our clients?
You will continue to receive the same personal service as before – now enhanced by a broader range of services. With the new colleagues at Auren, we can now offer you additional areas of expertise, including:
Legal consulting
Business consulting
Specialized advisory services in areas such as corporate restructuring tax law and international tax law
Further interdisciplinary services from a large, well-established consulting group
I am truly delighted about this step. It allows us to preserve the trusted quality and reliability of Goldstein Consulting while bringing in new impulses. It is particularly important to me that our team, through its integration with Auren, will also benefit from excellent long-term development opportunities in an exciting, forward-looking environment.
I sincerely thank you for your many years of loyalty and the trust you have placed in us.
I look forward to continuing to work with Auren as your reliable partner for tax consulting and auditing.
Warm regards,
Annette Goldstein
Managing Director, Goldstein Consulting
and the entire team of Goldstein Consulting and Auren
For the fifth consecutive year, we have once again made it into the top group of the Manager Magazine’s rankings for Germany’s best auditors. This makes us one of only two participants who have achieved an “excellent” rating every year since the first award in 2018. We were able to achieve one of the highest overall scores among all participating audit firms. We are incredibly proud of this and very grateful to our clients for this evaluation and the trust they repeatedly place in us and our services.
As in all previous years, such a success can only be a team effort, but it requires each individual to deliver their best performance every day and to fulfill their tasks with joy and high motivation.
I am grateful to all employees for this extraordinary performance and look forward to working with each and every one of them.
Naturally, we have intensely celebrated this remarkable success together and we look forward to continued collaboration with our clients, taking this award, as in previous years, as a significant incentive to maintain this quality, improve wherever possible, and continue to deliver excellent services to our clients.
Thank you to everyone who evaluated us.
In January 2025, Goldstein Consulting received the “Fairness First” award from the German Innovation Institute for Sustainability and Digitalization.
Companies with this award fulfill their corporate responsibility in terms of social, environmental, and economic aspects. This demonstrates that they act responsibly and transparently towards employees, customers, and business partners. This is also reflected in the services or products offered and their prices. A significant signal for all business relationships.
To achieve this award, a multi-stage analysis process had to be completed, developed by the magazine DUP UNTERNEHMER and the German Innovation Institute for Sustainability and Digitalization. Annette Goldstein and her team successfully passed this process.
As part of this analysis, digital touchpoints and brand presence were subjected to comprehensive social listening. Methodology, content, and scoring were developed by experts from various industries for this analysis. The results of these analyses were crucial for the overall evaluation.
According to the business magazine DUP, this makes Goldstein Consulting one of the flagships of the German Mittelstand.
Goldstein Consulting also sees this award as further motivation, especially to consolidate the digitalization goals already achieved, but also to meet its ecological and economic responsibility.

Your goldstein team
We are the auditing and tax consulting firm in Berlin that you have always wanted: Reliable with appointments, client-oriented, easily reachable, and with an eye for the essentials.
Our firm was awarded as an ‘Employer of the Future’ on March 14, 2023, by the former Federal Minister Brigitte Zypries. Daniel Baumgartner and Aydin Mammadov personally received the award in Hamburg.
The award is given by the German Innovation Institute for Sustainability and Digitalization to companies that work innovatively, digitally, and sustainably. We are proud of this and take this award as an incentive to continue attracting and, importantly, retaining the right talents for our firm in the future. Only through this can we use the increasing pace of innovation and the challenges of the constantly changing market as an opportunity.
In the April 2022 issue of Manager Magazine, we were awarded ‘excellent’ for the fourth consecutive time as Germany’s best auditors. We are one of only two participants who have consistently achieved the ‘excellent’ grade since the introduction of this seal and are among the firms with the highest total points.
We are very happy that we were able to achieve this award again and know that this is a performance of the entire team. We appreciate the assessment of our clients and take it as an incentive to achieve such performances in the future. We thank our employees for their extraordinary commitment and our clients for this excellent and trustful cooperation and will continue to make great efforts to meet the high expectations of our clients unchanged.
Furthermore, in April 2022 for the first time and in November 2022 for the second time, we were awarded the ‘Top Company’ seal by the employer-rating platform kununu, making us one of the employers with the best ratings on this platform.
We are extraordinarily pleased about this, as excellent performance can only be achieved by employees who feel comfortable and motivated. Maintaining and expanding this corporate culture is one of our most important tasks for the future.
We are very pleased about these seals of quality and look forward to continuing an exciting and hopefully equally successful cooperation with our clients. We are proud of every single client and take this as an incentive to further optimize our services with ambition in the future.
