I grew up in Chubbuck, Idaho running cross country and playing baseball, explored the streets of Buenos Aires for a few years, cheered for Cougar basketball when they were clawing their way out of obscurity, helped people face and overcome challenges in their lives, and do my best to be a good husband to Sara and father to Maren, Tom, Evie, and Josh.

I had an incredible experience with Snake River Law. Adoption is a very expensive process, and they helped us to accomplish it for a fraction of what we had expected to pay. They were always quick to respond and helped make sure we were on track. We wouldn't have our son with us now if it wasn't for their help! Incredible people and treated us like family.

Wow!! There is no way for me and my family to give you enough thanks! Such a great experience. Snake River Law
(Mark) was the best. He explained so many different ways for our family to be ok if something was to happen to us. You guys are the best from the phone calls the emails down to the walk to your front door. The staff is amazing as well. Never ever have I met a more bubbly Front staff. 5 stars all the way around. From my family to the snake river law family thank you for all you have done with your professionalism. I will be recommending you to everyone I talk to.

Did you know?
If you die without a trust-based estate plan, your entire estate is subject to probate.
Your estate will be subject to the control of state law, courts, and attorneys. Instead of your wishes and desires being carried out, third parties will determine where, when and how your estate will be distributed, after sucking away a portion of your estate to pay for their fees ($3,000-$10,000 average probate fee in Idaho). There’s also an average 6-18 month delay before your heirs receive their inheritance from your estate.
