Our Team

Andrew J. Chamberlain

I started the Chamberlain Law Firm because I like helping people. I chose Elder Law, Estate Planning, and Probate because these areas focus on important personal situations in everyone’s life, so it is easy to help, especially during a difficult time.

The mission of my law practice is to provide outstanding legal services in these areas by giving good advice that ensures my clients are well informed and know all their options. In addition, to draft comprehensive documents that account for a wide variety of circumstances in order to protect my clients’ best interests.

I also enjoy running a law firm and making sure our clients have a good experience. When helpful, we use technology to make the process easier and more expedient. However, when appropriate, we have in-person meetings to get to know our clients, and their issues, better.
