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

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 and Eka were very professional in handling my case. I would definitely recommend them to others and use them again. Jack has 50 years experience!- Michele

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

They are very very professional and very quick to respond so you're not left in the dark about anything to do with your case! I was very happy with the results of my case and my experience with them. I highly recommend if you're looking for a divorce lawyer or any kind of family law, Jack cavanaugh and his associates are great! I have to give a special shout out to Eka because she really made my life a heck of a lot easier and was always so quick to get back to me and let me know what is going on! I would give her 10 Stars if I could!- Courtney T.

He has worked with me even though we are in different states to ensure I am kept abreast of what is going on.- Former Client

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

Jack has been a lawyer for a long time. He values his clients and sees them as people with individual circumstances, and not just dollar bills like other attorneys. Anyone that knows anything about the law knows it’s about making and keeping good rapport with all parties involved. And for a defense attorney, being familiar with the judge to the prosecutor and being on a friendly basis with them is exceptionally important. And Jack knows everyone! He should as he’s been doing this for probably over 40 years. He’s not only a great attorney but I consider him a friend. Don’t make the mistake of choosing an unknown rookie attorney who may be a couple bucks cheaper. Choose Jack!- Paige
