Knowledgeable, friendly and great at communicating!
As a first-time landlord, I found myself in need of legal advice and assistance. Louis J Dagostine gave me a sense of needed confidence that things were being handled professionally. Thank you!

Incredible experience!
We happened upon Attorney Lou Dagostine when doing some internet research to find a lawyer who specialized in New Home Construction issues. From the very first phone call (which was returned promptly from an initial, brief email inquiry) Lou took the time to listen to our concerns (really hear and understand what we were saying). We were educated on what our options might be and advised that his goal is to handle our situation without us incurring unreasonable costs. His primary goal was to try to avoid litigation if possible, while negotiating a fair and reasonable settlement. Lou certainly held true to his word. We paid a retainer fee and received monthly invoices detailing the time spent on our case. We were kept well informed of the progress he was making, without having to request updates. It was extremely rare that I would contact Lou as he would reach out to us when something additional was needed, but kept the communication and progress going with the Respondent. Lou's confident, yet personable demeanor is carried forward during negotiations leading to results in an extremely reasonable time-frame. Our case was settled without litigation (although he made it quite clear to the opposing party that he would file the law suit tomorrow if need be) and within the amount of our initial paid retainer in less than 5 months. Considering we'd been trying to handle the situation ourselves for more than 2 years, this result is incredible. We are so happy to have stumbled upon Attorney Dagostine and his firm. As each lawyer in the firm specializes in different areas we intend to contact Ciulia & Donofrio, LLP for all of our future needs, such as having a Will prepared, which is something that we have been avoiding, but with the comfort level that we have experienced working with Attorney Lou Dagostine of Ciulia & Donofrio we have no reservations whatsoever.

More than we could even ask for
Louis helped us with a case where we were being overcharged and charged for unauthorized work on a new home. From the moment we met, Louis asked pointed questions and always kept our best interest in mind. He made clear what the law was, but also included a tremendous amount of knowledge about precedents in this area of construction contracts as well as an understanding of how judges would interpret the case. He was patient as we gathered our evidence, and consistent with communication about where we stood. In the result, he negotiated a significant (~75%) reduction as a settlement, avoided court, and allowed us to move forward knowing there would be no additional or future costs/actions - all the while never even exhausted our retainer. We were so very glad to have been recommended to Louis, especially since a number of lawyers we know and inquired with would not take the case because of the specialized knowledge required to really help us.

I wish there were a better than excellent rating.
Louis assisted me with a contract agreement/ review which provided me with insight and education that ultimately led me to the decision to go in another direction. As a new business owner Louis' expertise, in my honest opinion, paved the way for my future success. I am big proponent of educating the client to allow them to make the best decision without influencing them based on personal bias. Louis remained objective and explained every aspect of the process and defined all the legal jargon which revealed a much different picture from what the employer was verbally endorsing. I feel the time spent with Louis navigating that process was invaluable and would without any reservation recommend him.

Couldn't ask for a better lawyer
Lou was the best lawyer a girl could have. Not only did he empathize with my situation, but he went the extra mile to always keep me informed and clearly had my best interests in mind. I trust him 100% and feel he is an expert in his field. He puts the client first and truly makes you feel he is there to take care of you.
