Financial Planner for medical professionals, corporate executives and business owners.

Andrew Mohrmann is a St. Louis, MO fee-only financial planner. Modern Dollar Planning provides comprehensive and objective financial planning to help clients organize, grow and protect their assets through life’s transitions. As a fee-only, fiduciary, and independent financial advisor, Andrew Mohrmann is never paid a commission of any kind, and has a legal obligation to provide unbiased and trustworthy financial advice.

Modern Dollar Planning is a fee-only financial planning firm in St. Louis that serves physicians, corporate executives and business owners. 

As of December 2014, I had a great job at a respected company that did exemplary financial planning and investment management work with high net worth clients.  I worked with bright colleagues and had interesting clients in what was a great long term opportunity.

But I felt a call to do something different.

During my time there, I had personal friends, classmates from my MBA program and other acquaintances begin coming to me looking for help with their finances. Most of these folks were in their 30’s and 40’s. The question they kept asking was: Could I become a client of yours?”

Unfortunately, the answer was all too often "No".

Most firms that act as fiduciaries have minimums that my peers and colleagues don’t meet. They are forced to go elsewhere for advice and are often 'sold' financial products that in many cases, might not be right for them. 

With Modern Dollar Planning, I've developed a package that will set young professionals on a new financial trajectory. This new model will allow my peers to get access to the type of quality, objective advice that wasn’t available to them up to this point through an affordable monthly retainer.  I now have the chance to pair my background as a CFP® and an MBA from Washington University in St. Louis with my deep-seated passion for entrepreneurship.

It's an opportunity to help my peers start making smart financial decisions, simply and confidently.
