My experience with Mr. Cavanagh was very pleasant. I was kept informed about what was going on with my case. Phone calls were returned promptly and everything was explained to me. Knowledgeable, personable and fair - can't ask for much more than that. He was on my side. One more thing.... he's not a pushover when it comes to the opponent! Love it!- Terri Buckner

First of all, it was hard to find a lawyer that works with grandparents rights. Jack did a great job and we get to see our grand-daughter for the first time in a year. We are very thankful to him.- Mr. Callaway

Jack took over my divorce case and made a seemingly endless divorce process (nearly 4 years with mediation, continuances and a former atty.) come to a quick and agreeable settlement. Jack is an effective and seasoned attorney that made easy work of the negotiations. He is respectful and concerned for his clients. His associates were friendly and helpful, ensuring that all paperwork was completed in a timely and accurate fashion. I highly recommend him if you are going through a difficult divorce.- Carol

Mr. Cavanagh was very patient in dealing with all of the difficulties of my case. He was pleasant to work with to get the child support and custody worked out in a way that was fair. He showed real concern for the welfare of my son. He was professional in guiding me with regards to counseling and getting my sons voice heard throughout the case as well. Lastly he was thorough in that he went through the original divorce decree and made sure I received what I should have gotten during the divorce. I would recommend Mr. Cavanagh as well as use him again in the future.- Former Client
