What Our Clients are Saying

“We have used the Tsongas team many of our most important cases. They offer solutions, not just observations. They provide case-specific recommendations, not just boilerplate suggestions. They work with us and our clients to develop a cogent and meaningful approach to our most challenging issues. They have become part of our trial team, not just a bolt-on accessory. I have not found a more talented group.”
