How The Giersch Group Started
The story of the Giersch Group goes back to 2004 when Peter Giersch started Cathedral Consulting Group in his basement in a small suburb north of Milwaukee, WI.
Over the next decade, Cathedral Consulting Group grew into a multimillion-dollar, multi-national firm under the leadership of Peter’s then-partner and CEO of Cathedral Consulting, Phil Clements. After Clements’ passing in 2015, Peter withdrew from the firm he co-founded and started the Giersch Group to carry on the tradition of excellence in consulting for small businesses and grassroots nonprofits.

Professionals with a Passion for Small Enterprise
Every person who works at the Giersch Group has a passion for small enterprise, and many of us come from families of entrepreneurs and/or family businesses. We take pride in providing affordable professional services for Milwaukee area business owners and nonprofit managers.
While there is a place in this world for institutions and corporations, it is the small business owner or non-profit volunteer who is our hero. It is our pleasure to support the free market and the entrepreneurial spirit by using the best corporate and institutional practices adapted for the small enterprise.
Effective planning starts with knowing the numbers and making decisions based on them. Our bookkeeping, virtual CFO and board services are how we do this, and are at the heart of what we do. Basic human resources tools, accounting software setup, marketing & sales support, grant writing and fundraising are other specialties we offer our clients.
Our bookkeeping, consulting and nonprofit services define the relationships we have with our clients. Mutual trust and respect sustain them.

Countless studies show that there is no correlation between money and happiness; those who are wealthy are not necessarily happier than those who have less money, and vice versa. According to the Washington Post, once people surpass the level of poverty, money does not play a great role in day-to-day happiness. Yes, money can buy goods and services that bring temporary enjoyment, but these things do not directly address, let alone fix, the troubles people experience in their daily lives.
If money only provides temporary enjoyment, then what’s the key to happiness? According to a study at the University of California Berkeley, having higher quality of relationships has a greater impact on one’s quality of life and their overall happiness. By focusing on the well-being of others, people who are compassionate, generous, and generally cooperative have greater relationships between their colleagues, clients, family, and friends.
The Giersch Group logo represents the importance of balancing relationships and maintaining financial health. Our logo is a graphic representation of the fact that relationships are more important than money while acknowledging that money gets involved in every relationship at some point, especially for a business owner. Getting your financials sorted out will improve relationships and make you happier.

Will your business beat the odds?
Your ideas can be brilliant, the market can be there for your services, but an unhappy relationship with numbers ruins everything.
Just a couple of unexpected cash flow hiccups made worse by the wrong action (or reaction) can be enough to cripple or kill a business when the numeric relationship is unhealthy.
A requirement for working at the Giersch Group is being a good communicator. A lot of new clients come to Giersch Group because their former accountants did not communicate with them. Communication is our number one core value, along with speed, accuracy and security. In addition to the monthly package you'll have access to a dedicated client controller that you can communicate with at any time. Our commitment is to answer every email the same day and to try to resolve issues within 24 hours. We’d love to hear from you about what you are looking for in an accountant, contact us today.
