Heike Kolossa
I am responsible for tax and business consulting.
Numbers are my element – they speak a clear language. And it is precisely in this clarity that I find my strength. I support our clients in all tax and strategic matters with foresight, precision and reliability. For me, developing intelligent concepts for the tax optimisation and sustainable positioning of companies is not just a task, but a real passion.
I particularly enjoy working on complex issues where I can utilise my structured way of thinking. When it comes down to it, I’m there – direct, solution-orientated and with a keen sense for the essentials.
I see my next professional qualification as becoming a chartered accountant – because further development is just as important to me as reliability in day-to-day business.
For me, my law firm means: a place where performance, trust and warmth of heart can work together. I do my utmost to achieve this every day.

Vanya Weiss
I support people and organisations in finding clarity, trust and new directions in the midst of economic complexity. My work begins where structures have become rigid and space for change is needed – with an open heart, strategic thinking and a deep sense for the essentials.
What drives me is the longing for genuine solidarity and a sense of purpose in economic activity. I believe in companies as places of growth, responsibility and togetherness – if they have the courage to break new ground.
My strength lies in listening, recognising deeper potential and guiding people through challenging development processes – calmly, clearly, solution-oriented. I love meeting people with a vision and supporting them in transforming it into a stable and fulfilling reality.
I speak fluently: German, English, Spanish and Bulgarian.
And fluent in the language of heart, clarity and future.
