Seth K.

Had a great experience working with this firm. Specifically, Chelsey Christiansen. She assisted me with out of state child custody and support litigation and I am extremely pleased with the outcome, not to mention the professionalism she exhibited in both her communications with me, but also those she had with opposing counsel. Highly recommended, 5/5 stars!

Michelle L.

“I contacted High Swartz to help me navigate the custody issues I was facing with my ex, and I have been so pleased with the services I received. Chelsey Christiansen has been extremely helpful in helping me determine what was best for my child and myself while also remaining realistic. She was determined to have everything settled amicably, and thanks to that attitude my ex and I came to an agreement without having to take things to court. I’m very happy that I had Chelsey in my corner to advocate for what I wanted and what my child needed.”
