Family First

Since starting in financial planning in 2007, our first clients were family. As we grow, our philosophy stays the same: Treat clients like family and everything will take care of itself. We believe this is the primary reason clients partner with us and often refer their friends, family, and colleagues. As a fee-only firm, Costello Financial Planning does not sell any products, and it never receives any commissions or kickbacks. Clients work with us because of our evidence-based philosophy and ongoing client-centric approach.

Costello Financial Planning has worked on a multitude of financial planning issues with clients. We use a consultative process to gain a detailed understanding of each client’s deepest values and most important goals. We then employ customized recommendations designed to address each client’s unique needs. We develop a specific investment portfolio, tailored to each clients’ risks and goals, and we form a partnership with our clients to guide them through life’s challenging financial decisions. This strategic process helped clients stay their course through the 2008 financial crisis and eventual recovery. Our clients find that working with fee-only financial planners in Ann Arbor and the other communities we serve is the right way to go.

If you are in need of a professional, we are happy to provide you a referral. As a fee-only firm, we do not receive any compensation for our referrals.

Formulating a good plan is very important to your financial health, just like an accurate diagnosis is important in addressing a serious medical issue. A good plan, like a good diagnosis, requires a financial planner to ask the right questions and to assess accurately where things stand. So is a good plan the end of the job? Hardly.

A good plan, standing alone, just like an on-the-money diagnosis, does not solve the patient’s problem. The plan must be followed by a meticulous follow-up and execution. That is every bit as important as meticulous treatment for a medical issue.

So what exactly is it that we are proposing that will make your life better?

We see clients who are fairly well-read, but for lack of time or simply out of fear of the unknown, find it difficult to consistently manage a particular financial plan.
