Are you using the same team of professionals for..
your personal taxes, financial planning and business?


Bookkeeping & Payroll Services

You work hard enough, therefore let our professionals keep track of the financial status of your business for you. We are professionals in Quick Books and payroll taxes. 

Accounting & IRS Representation

Faced with an audit? As enrolled agents or ‘EAs’ Drenen has the power to represent you in a crisis. Surely we will help mitigate what you owe. 

Financial Planning & Investments

Whether it is college planning, real estate or even divorce we have the financial knowledge to help direct you to the best outcome. 


Tax mitigtion and financial planning combined together

Even the best laid financial plan can be completely undone by taxes and changes in tax laws, taking with it any gains and profits you made in your portfolio, personal income, or business (if you have one). If you have a separate accountant and financial planner, they may

have all the knowledge, experience, and information you need to provide you a comprehensive plan that helps position you for the lowest taxes and the safest, highest returns. That’s why the Drenen Financial Services philosophy is that tax mitigation and financial planning surely go hand-in-hand.

We protect those in higher-income tax brackets with larger portfolios, estates, and inheritances from overpaying in taxes with a combination of tax mitigation strategies, tax-sheltered investments, and other creative solutions.


There is much more strategy involved in college planning than just putting money into a college fund. Even if you are not sure if your child is going to college, it’s important to plan as if they are. It’s never too early to plan, but if your child is in high school, it’s even more important to put a plan in place quickly.


We help bring calm and peace of mind to individuals and couples who are contemplating or moving through divorce, in valuing and separating their assets and liabilities and determining the best tax filing strategy during the transition.


We work with other service professionals and firms, such as attorneys, financial planners, accountants, real estate agents, architects, and others to support you, provide complementary services, and give your clients a full-service experience. We’d love to get to know you and work with you.


There are specific issues that medical and dental practices face that need to be taken into account when it comes to tax time that other accountants and financial planners may miss.


Restaurants and caterers are businesses that deal with a lot of cash, part-time help, and inventory. Accurate bookkeeping and tax planning is important to preserving what you’ve worked so hard to make. Drenen can protect and help with IRS audits as well.
