Proven experience, knowledge, and professionalism.
I retained Mr. Manni for a civil matter. During that case Mr. Manni was efficient, direct, and knowledgeable. I was treated with respect and dignity throughout the process and with Mr. Manni representing me, I felt immense confidence in the outcome. Mr. Manni has remained courteous and professional above and beyond his duties. I would recommend this attorney.

Best Attorney. Don't bother looking anywhere else!
I was involved in a 4+ year contentious divorce that covered 3 states, two false rape accusations and 2 small children. I simply cannot make this up. David Manni handled my case with exceptional professionalism, honesty, commitment, and tire-less determination that I can only describe as "Life Saving". I am a professional who stood to lose everything and because of him I have full custody of my children and a fresh start in life. He always returned calls and emails and made himself available as we prepared for trial and never waivered on me. His drive and determination kept me going when there were times I felt like quitting. He made me believe again that there are people who still care and believe in justice. I consider him " a brother" and will always be thankful that I chose him and he took my case. Finally, we negotiated a settlement without going to trial, saving thousands of dollars, time and mental anguish. There are not enough words to describe David as an attorney, person and friend. It would be a travesty if he did not one day become a judge. The world needs more David Mannis.

Efficient and Professional
I highly recommend David Manni's legal services. He is all business, will handle your case honestly, and will not run up the bill. He handled my divorce case with a contentious wife and we resolved the issues thru mediation without going thru the psychological trauma of going to court.

Divorce with Children
David represented me in tideous divorce case involving children. He was professional, respectful, honest, communicative and acted with the utmost integrity. I could not be more pleased with the way my case was handled, or the results. Rates were reasonable, work was efficient, accounting was accurate and punctual. David is a skilled and experienced attorney who will serve you well. I felt like I was in good hands throughout the entire process. If you are in need of legal representation, I would highly recommend contacting David and his firm.

Awesome Personal Injury Lawyer
Mr. Manni was extremely professional handling my personal injury case. He went above and beyond to get exactly what he felt I deserved. He is fair priced and efficient. Always available to answer questions and returns all calls and emails. I had so many questions as I don't know any of the legal terms and he made sure I understood before I would hang up or leave. Everyone in his office is very friendly and helpful. Will definitely be hiring him again in the future if I ever need a lawyer again. 5 stars all the way!

I was in need of an attorney, and just opened the yellow pages, and chose one at random. That was the day I realized someone above was looking after me. I meet Mr. David Manni and liked him from the beginning of our introduction. He was pleasant, polite, informative, and told it like it was, so I knew from the beginning where we were headed. He did as he said he would do, and I have high respect for a man that is a man of his word. I an truly thankful that by chance he came into my life at a time of need. I would highly recommend him to anyone. Thank you David for all you did for me. Sincerely, Tom
