With a lot going on in my personal life, de Bakker and de Bakker made my estate planning a breeze. They walked me through difference scenarios and answered all of my questions to my satisfaction. I’m confident that should anything happen to me, my wishes will be well known and straight forward.

Peter, Thunder Bay

I was charged for assaulting my ex-girlfriend. Mr. de Bakker helped me from the beginning, even before I was arrested. The process took longer than I thought it would, but I was happy with the outcome. Would recommend.

Michael, Thunder Bay

When my husband and I bought our first house we did a private deal. Johnny helped us with the offer, all the way through to closing. His staff was courteous and professional, we will definitely use them again!
