Hired Attorney Joseph Thelin

Mr. Thelin goes the extra mile to explain and advocate for his clients, especially in family conflicts regarding guardianship, and co-trustee laws. If there’s a doubt, he doesn’t hesitate to discuss such matters with his partner, regardless of the time it takes, he gets it right. He is patient when the client is not clear, and takes whatever time it requires to ensure there’s a clear understanding as he navigates through the legal process. When needed, he takes the initiative to move expeditiously. We are fortunate to have him represent me. It’s freeing to have an attorney you can feel confident in, and trust his knowledge of Virginia laws.

Hired Attorney Arthur von Keller IV

Mr. VonKeller is an AMAZING lawyer. I needed a strong lawyer to handle my complicated case. He is extremely knowledgeable and truly loves his job- he will be compassionate to you and what you are going through and be a bull in the courtroom. I would highly recommend him to any body that I know that is going through a custody battle. He is also a guardian ad liedem for the courts, so his best interest is ALWAYS the children involved.
