Meet DAVID. Lawyer and Owner.

Divorced with three kids, David understands personally the complexities of family law and the importance of protecting loved ones.

What CLIENTS are saying:

“David always kept me informed of the current status and next steps - I was never left wondering. I was, and still am, very pleased with the beginning, middle and end of how my case was handled. Should I have any need for an attorney in the future, my go-to will be David.”

– Danielle.

“I can’t say enough good things about Dave. I first contacted him for a divorce that I expected to be short and amicable. Soon after contacting him, that changed and it became a lengthy divorce and custody situation. He swiftly and expertly navigated every issue that came up. Working with him calmed my anxiety through a very uncertain process. He answered every question I had and was very communicative through the whole process. I have already sent several people his way and will continue to do so. I would recommend him to everyone I know!”

– Anonymous.

“David Marquardt helped me in a custody and child support case against my ex-wife. I couldn't have asked for a better attorney and person. Mr. Marquardt was patient and explained everything to me in words that I could understand. He helped me obtain the result I wanted and, more importantly, seemed to genuinely care about me and my kids.”

– David.
