Estate Planning

We can guide you in crafting an estate plan that will improve the well-being and quality of life of those you care deeply about, one that will reflect your individuality, built around your voice, your values, and your beliefs. That means your plan not only can pass along what’s important to you but can provide tax, asset, divorce and lawsuit protection while helping maximize your property values.

We’ll help you see the opportunities in front of you. We’ll provide practical, easy-to-understand answers to all your questions. And we’ll ask some of our own along the way, too, all to get at your core motivations and desires. We then can employ the right tools, strategies and techniques to overcome any obstacles that may exist and craft a plan specific for you, your family and, if applicable, your business.

Equally important, we’ll work with you to implement your plan, and we offer an affordable maintenance program that helps ensure your plan will work for you throughout your lifetime. Through annual reviews and meetings, we’ll modify your plan based on changes in law, taxes, or your own circumstances and life events, such as the birth of a child, a divorce, or a death in the family. If you have questions, we’ll be there. And when it’s time to pass along your wealth, we’ll be there for your family, too.

Business Law

You’ve invested too much money, time, and sweat to get your business where it is today, and you can’t afford missteps now. Even if you’re just starting out, every move is critical, and the wrong ones can set you back years.

As a firm that concentrates on serving small and family-owned businesses, we know the challenges and opportunities that await you. For more than 25 years, we have worked with hundreds of start-up, growing and successful small businesses in all phases of their life cycle – from formation, to strategic partnerships and growth, through ownership transitions and exit strategies.

We know that conducting business in today’s increasingly regulated climate is difficult and that many small-business owners can’t keep up. Not only can we help keep you in compliance, but we can help you use the laws to your advantage as you minimize risks, sidestep potential problems, and make the strategic decisions that position your company for success.

We are proactive and work hands-on with our clients. It’s an approach that saves our clients time, effort and money. Firm owner Don Sadowski’s family owned a small business, giving him an appreciation of the challenges and rewards of entrepreneurship that he brings when helping companies today. In addition, we’ve worked with clients in a variety of industries and understand the many environments in which businesses operate, the forces that shape them, and the legal issues that can impact their success.

Tax Law

What’s rarely mentioned is the third – the headaches taxes usually cause when you don’t have clear tax objectives or fail to plan for tax savings.  Whether you’re an individual or a business owner, almost everything you do has a tax consequence. And this isn’t child’s play. Make a mistake, and you can face financial loss, penalties or worse. At the very least, you can’t afford to shortchange yourself or miss tax-savings moves or opportunities to protect and maximize what you’ve already worked so hard to acquire.

And with the tax laws constantly changing, along with the intricacies of federal and state-specific regulations, how in the world can you keep up?

It starts with a sound plan and professional advice. That’s why we incorporate practical and cost-effective tax-saving strategies into each personal financial and business transaction our clients undertake. It means not only ensuring that you’re legally compliant, but making sure that everything’s working for you and your interests. We speak the language of CPAs, accountants, CFOs and other financial specialists, and we’ll work with yours to develop and implement legal and creative solutions that help you achieve your business and financial goals while saving your tax dollars.
