John has done (and redone) our revocable trust. He's wonderful to work with. Very thorough and makes sure everything is understood.

John Horn did a great deal of work for my family, starting with the creation of a living trust for my mother in 2019. He stuck with us for three years, creating a trust for my husband and me, and another for my brother. He also provided sound advice about my my aunt’s estate, a challenge for us all as she was a resident of California.

We benefitted from his knowledge and experience, but also from his patience and willingness to explain – in simple terms, the mysteries of a trust. While I appreciate all that he did for us, I especially appreciated his patience.

I recommend him without hesitation.
