Dimosthenis:

Optima Justitia Law Firm assisted me in recovering the wages owed to me by my employer, who had also required me to work overtime. The matter was resolved swiftly through an out-of-court settlement. I was entirely satisfied with the outcome and I highly recommend the firm to others. I would also like to highlight the firm’s transparent fee policy; I was provided with a clear and detailed explanation from the very first consultation.

Alexandros:

I was looking for a lawyer online. I sent a message to OPTIMA JUSTITIA through their website. They contacted me immediately. I wanted to set up a company based in Thessaloniki. I spoke with Mr. Giannoulis via the Zoom app, as he was away on business in Athens at the time. A colleague from the firm got in touch with me right away, and the process began. I was very satisfied. The procedure was completed quite quickly. At that point, I paid the firm's fee. The fee was appropriate for the high-quality services the firm provides. I appreciated the clear terms regarding payment. There were no additional or hidden charges. Mr. Giannoulis informed me from the beginning about the cost of each legal action. I wholeheartedly recommend this law firm. I, for one, won’t be changing lawyers anymore.

Maragrita:

I wholeheartedly recommend the law firm. Mr. Giannoulis is an excellent lawyer and, above all, a true gentleman. He helped me with my family law case. He and his associates are specialized in family law, particularly in matters of custody and child support. I was very satisfied. He explained his fees to me from the beginning. Their fees were reasonable, considering the high-level services they provide. I wouldn’t change them for anything.

Hubert:

I sent a message through the website, and the law firm reached out to me very quickly by email. Mr. Giannoulis and his team were truly kind and professional. I needed assistance completing a property sale in Chalkidiki. From the beginning, they were clear about their fees, and I truly appreciated that they themselves suggested I pay only after the process was completed. And indeed, I paid only once everything was finalized. Although I had to wait a few months due to Greek bureaucracy, that delay had nothing to do with Mr. Giannoulis. Throughout the process, he kept us informed and explained every step in detail. I’m genuinely glad I worked with him. He handled everything with honesty and care. I would definitely choose him again. An excellent lawyer.

I sent them an email. I received a quick response. After I explained the problems I was facing with my job (non-payment of wages), they advised me to take action immediately. They contacted my employer The case was closed out of court due to their actions. I was completely satisfied and I highly recommend them. Their compensation was generous for the services they provided. The terms were transparent and known from the beginning.
