Very impressed!!

Mr. Mandi is an excellent attorney that did nothing but benefit my case. He’s a very compassionate and empathetic man that listens to everything you have to say and can see the situation through your eyes. There was never one moment where I felt alone, he was always on top of every aspect of the case. I would not hesitate to re-hire Mr Mandi if needed again in the future.

Great Lawyer

Great lawyer to me. Peter was very helpful and knew what he was talking about. He made things a lot easier to me. The process could have been quicker but that was not Peters fault at all – it was mine and the ex’s for dragging it out. He was very patient and showed no frustration at all. He answered all phone calls and emails quickly and had answers for all my questions. Would definitely recommend Peter to anyone.

Thank you Peter…

When I walked into Peter’s office I didn’t know what to expect or what was going to happen. He helped me through what I thought at the time was my most difficult time of my life. He didn’t make it mean and dreadful which is what I expected from divorce.. He helped me through each step of the process explaining what I should expect and in what time frame. He guided me to accept what was right and to push for what I was entitled to.. Most important he made it painless and straight forward … Thank you Peter!!

Top Notch

I enlisted the legal services of Peter on Legal Match to handle a child support issue in family court and I am very pleased and satisfied with the final outcome of the case. Peter is attentive and knowledgeable in the practice of family law and I will definitely reach out to him again for his legal expertise should the need arise again in the future. Thank you Peter!!!

Great attorney

Peter is an excellent attorney. He helped my ex wife and resolve our differences and come to a mutual understanding. He was always available to answer questions and concerns. His professionalism and non bios neutrality made him the perfect attorney for both of us. My divorce was settled out of court and only cost me approx 3000 dollars from start to finish including court filing fees ect. Great professional attorney with a great personality. Highly recommend him !

An honest lawyer- for a change!

Peter Mandi is a rare find- an honest, down to earth and savvy lawyer who truly excels in client service. His knowledge of the law coupled with a delightful bedside manner, make him an invaluable advocate for his clients. In my experience, he literally rescued my case which other lawyers (who shall remain nameless) blundered. I will recommend Peter to everyone and anyone who needs legal counsel.

Great Attorney!

I will definitely continue to highly recommend Peter. Peter was understanding and always kept me informed at all times of what was happening in my case. I would also like to mention he always responded very quickly to any questions I may of have during the case and even now that my case has been settled whether they were on the phone or through email. I felt very comfortable working with Peter during my case and so has everyone who I have recommended him to.

Painless Divorce Process

Comprehensive Consultation – Just that – comprehensive! Answered all my questions patiently and reviewed all my options. Peter acted as Mediator for our divorce and was extremely knowledgeable and very thorough. He was respectful and professional and worked quickly to help us come to a fair agreement that we were both pleased with. He kept us apprised of any updates along the way and made the entire process less painful than I would have ever imagined. I have no doubt though, had we gone in another direction, that I would have been well represented.

Dedicated to Finding a Solution

Peter handled my child support case after I hired my first attorney. He quickly got up to speed on my case and took control of my situation, clean up the mess from the previous attorney and met all my expectations. We always planned before hearings and communicated well with me during hearings. He fought and defended when necessary and recongized when to back off. Most of all Peter was dedicated to finding a solution and negotiated with the other side. I would recommend Peter and I would absolutely hire him again.
