What Our Clients Say
June 2, 2025
Getting a little older and having a special needs child, we explored some trust options with Andrew Knutson. Andrew helped us to quickly clarify what we really needed and guided us through a very painless (for us) solution. We were impressed with his comprehensive estate planning and tax law knowledge. We are now very relaxed and content that all will be handled well in the future.
