“ I needed to update our family‚Äôs estate plan and was looking for a knowledgeable attorney who was in the South Shore area. I felt very comfortable choosing the firm of DeRosiers, Tierney & Sheehan, LLC because estate planning is their sole practice. Our estate planning included a Special Needs Trust for my daughter and I wanted to make sure this was set up correctly. Attorney Katherine Sheehan provided expertise with all aspects of the update process and met with me several times to explain in detail what each planning document was, why it was required and how it all worked together. I am very pleased with the results. I look forward to working with Attorney Sheehan in the future. ”
