I recently spoke to John Mager about retaining him to represent me for my custody case. I was highly recommended to him by another top attorney that represented my friend in another area of the state. John was not able to take my case because the courts dates conflicted with his schedule, but John was extremely compassionate and spent over 45 minutes on the phone with me (and I concluded the call, not him, he seemed as if he would stay on the phone as long as I needed, even though I know he was very busy with other cases) , providing me with advice on how to find another attorney, and gave me some recommendations on who to call. I was really impressed with how kind John was to spend this time helping me just out of the kindness of his heart. It is such a difficult task to find a good attorney, so I wanted to offer my advice since I have done some homework on this, and what I can say is that the attorney that referred him has excellent results in Stamford courts and he wouldn't have recommended John if John wasn't great with this area of the law.

Helped Me
Attorney John Mager helped me with a boyfriend who became abusive and began to stalk me. He quickly put an end to it. He stated, "I don't think you will hear from him again." I didn't. I also used Attorney Joe Mager for a closing on a house. He seemed to be extremely busy and it was hard to get ahold of him, but everything was done correctly and I had no problems.

Exceptional Client Support
Attorney Mager has been extremely responsive and helpful in dealing with the issues surrounding my divorce case. I am thankful to have him representing me and know he has me and my son's best interests at the forefront. I would highly recommend him and his firm.

John Mager Review
John and his team are dedicated in their pursuit to get the best results possible for my case. I am kept up to date, they keep everything moving along, calls are returned, meetings are easily scheduled. I have referred friends to Mager & Mager who are also satisfied with a job well done. I use John for all my legal needs, he is professional and knowledgable about many aspects of the law and has always proven to get the job done.

I have recommended John Mager to several people
When it comes to family law, john mager is the best. I always felt he looked out for my best interest. When I suggested certain options during the process, he gave me great advise and council as to what would be better options. He is extremely knowledge and engaged in the area of family law. As most divorces are difficult, my former husband created many obstacles and issues during the process. John would not tolerate the nonsense and went above and beyond his role to assist me. I appreciate that John is not the type of attorney that seeks billable hours. He is more than fair. John is very busy- as most great attorneys are. If you can be patient and understand that he is working many cases, you will get the best council. I spoke with 4 attorneys before I retained John. I certainly made the right choice!

All law firms should be this way
I have had the pleasure of being John's client for over 25 years. I would highly recommend him to anyone looking for an attorney who is honest, has integrity, and produces successful outcomes like he does. John is extremely knowledgeable in all areas of the law and is not limited to only one specialty. I have retained him for different law issues thoughout the years and I was always comfortable with his advise and recommendations as well as the result. His law firm was started over fifty years ago by his father and has always been highly respected. That excellent reputation continues to the present day because of John's ability to get the job done. You'll never make a mistake with John as your attorney.

Highly recommended
John is an excellent client advocate, who will listen, advise and drive the chosen course of action. John helped me with a family law matter, which extended over a number of years. He proved to be an excellent resource, advisor and advocate. I highly recommend him!

Personal Injury representation
I am working with John Mager on a personal injury case. He has taken the time to explain the process and the steps required to resolve the case. He is very pragmatic in his aproach to the litigation, not looking for outrageous settlements. I have a great deal of confidence in John and expect that he will resolve the claim to my satisfaction. I would definitly recommend John to anyone looking for legal representation for a personal injury claim.

Sound well thought out strategy and legal advice
John provided excellent legal representation and guidance. He did not sugar coat unrealistic outcomes to my divorce case. He provided realistic and probable outcomes, opinions and alternatives and not just what I wanted or hoped to hear. I enjoyed working with him as John has a client friendly personality and is easy to work with. I found his presentation and negotiations skills to be very professional and well thought out. John has a very good courtroom presence but also works well in smaller forums and face to face negotiations. I would recommend John without reservation. John guided me through a trying 2 year period of my life. I have also recently used Mager & Mager to do my home closing which was problem free.

John is an attorney that will go above and beyond, I am so glad he was on my side.
Mr. John Mager treated me with the utmost respect and sincerity from the moment we first met. He handled my case expeditiously and remained in close contact. He was always a phone call away. No detail was overlooked. He was very persistent in making sure everything was right and was able to protect me and my children from what could have been catastrophic. He took the time to understand me personally and was sensitive to the difficult decisions I had to make. The outcome of my case was better than anticipated. It was truly a pleasure to work with John and to have him on my side. When, or if, I need legal advice in the future, John Mager will be the first person I call!

Review of John Mager based on a 20+ year relationship
My family and I have engaged John Mager and his team for help with multiple and varying life events over the last two decades. Our experiences have consistently been excellent from several different perspectives: i.e. client service, legal advice, outcomes, referral(s) to other professionals (contractors, other attorneys, etc.). As a result of our relationship, I have referred many people to him who have had the same experience as my family. I continue to hold a very high opinion of John as an attorney and individual and highly recommend the use of his services.
