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

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
