estate planning attorney Ryan Pomerleau


My practice at Legacy Law Firm focuses exclusively on estate and business planning. I am dedicated to helping my clients protect their loved ones, preserve their assets, and leave behind a lasting legacy.

I have worked with hundreds of individuals, families, and businesses to plan for their futures.  Whether I am preparing a client’s Last Will and Testament, helping a family create or administer a trust, or guiding a business owner through a corporate merger, I like to bring a common-sense approach to even the most sophisticated legal issues.

At Legacy Law Firm, P.C., I enjoy being able to concentrate on the specific practice areas that I love, surrounded by a team that is devoted to providing first-rate legal representation and great client service.  I previously worked at Thompson Law, P.C. in Sioux Falls.

When I am not in the office, I spend most of my time with my wife, Heather, trying to keep up with our daughter, Joanna.
