What our Clients are Saying

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.

Outstanding Representative

After being served custody papers from my ex daughter in-law I was about to concede. Being a recently widowed grandfather, I didn’t think there was any way I could retain joint custody of my grandson. Peter reassured me that I had a very good chance to win the case. With Peters help we wound up with a settlement that is fair to both sides.

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!!!

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!!

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.

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.
