About me

Lending you an ear. Giving you a voice.

The “team” approach has already received glowing reviews and achieved lasting results with a growing number of couples we have represented in the Maryland area. We can help you too.

Collaborative Law stresses mutual respect, rational discussion, honesty and a shared commitment between all parties involved.

Ours is a calm, unselfish means of blending the facts and emotions of your lives into a productive process for resolution.
