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

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
