Every engagement is different – but there are some areas we know so well that we've made them our specialties. Startups that need fast, clear direction. Real estate, where decisions echo across generations. Nonprofits and payroll, where real people stand behind every statement. Four areas, one shared commitment: advice that listens, thinks ahead and follows through.
You founded a company, not a tax firm. Even so, decisions have to be made that shape your tax future – often under time pressure, and without a clear picture of what really matters right now.
That's exactly where we come in: we walk you through it, separate what's essential from what's secondary, and give you a clear line on your tax obligations and options. No jargon, no off-the-shelf packages – just advice that understands how startups tick.
We know the typical pitfalls from founding to scaling, and we support you with the empathy and directness you need, so you can focus on what you do best: building your company.
„I know the tax challenges that come with a startup – from founding through your first funding rounds to a growing team. I work my way into your specific situation instead of running through standard processes, and I give you an honest read on what's a priority now and what can wait. With me, you have an advisor at your side who thinks with you rather than just running the numbers.“
Real estate is more than property – these are assets whose impact spans generations. Whether buying, selling, managing or transferring: the tax questions are complex, and often highly individual.
With over 20 years of experience in real estate, we guide you through this terrain – nationally and internationally. We're reachable when it counts, we bring the tenacity to work out constructive solutions even in difficult situations, and we think long-term: securing your assets and passing them on strategically.
What drives us isn't the single engagement, but the partnership that grows out of it – well-grounded, dependable, and with a real understanding of what's at stake in your decisions.
„For over 20 years, I've worked on the tax side of real estate – nationally and internationally. Beyond my experience, what sets me apart is a willingness to dig into complicated situations and to stay with them until a workable solution is in place. Especially when it comes to long-term asset protection and transfer, that approach makes the difference.“
Payroll sounds like routine – but it isn't. Behind every pay run stand legal requirements, individual company structures and people, for whom timely, accurate payment is not a detail but a matter of trust. We know that.
That's why you get a personal contact who knows your company, delivers reliably, and handles the balancing act between rigid rules and your operational reality. No anonymous processing, but a partnership where sensitivity is no foreign word.
Because anyone responsible for payroll carries responsibility for what reaches your employees at the end of the month – and with it, for more than just a number in an account.
„I know that payroll isn't a purely administrative matter. I know the balancing act between legal requirements and what actually happens in your company – and I bring an understanding of what accurate, on-time pay really means for your people. What counts for me is being personally reachable, reliable in delivery, and attentive to detail.“
People who run a nonprofit association or organization usually do so out of conviction – not out of a passion for bookkeeping. Even so, as a board member you carry responsibility for accounting, budget discipline and correct reporting to members, tax authorities and funders. Nonprofit law is closely tied to financial questions, the requirements are complex – and mistakes can put your organization's status at risk. We take on your commercial back office: from accounting through budgeting and cost control to use-of-funds documentation. That way we create transparency for everyone involved and give you the confidence to focus on what you set out to do.
„Since 1994, I've worked at the interface of the tax office and nonprofit law. This holistic view of the subject helps me find workable solutions even in complex situations – and to stay with them until they hold. Anyone doing nonprofit work deserves an advisor who understands the particular responsibility behind it.“
