Are you an attorney? Endorse this lawyer

    I endorse this lawyer. I had a case against Attorney Diel several years ago and I was very impressed with her legal abilities and the way that she handled herself during the proceedings. I would have no problem referring family members and friends to her in the future.

  • Joseph C Noto

    I endorse this lawyer. Diane trained me in collaborative law over 6 years ago in New Jersey. She is an active, very involved and influential member of the I.A.C.P, of which I am a member. I would recommend her at a heart beat if a client asked me who I know in her state to do a collaborative divorce.
