VICTORY

Konstantine and his team are absolutely THE BEST! Not only was he available with short notice for trial ( less than a week) at the time of trial he was fully knowledgeable of my case and WE WON!! I can't say enough about his sensitivity regarding my probate matter going against family is tough enough... but his knowledge of the law WAS AWESOME! THIS guy is a beast in the courtroom. If your looking for an HONEST ATTORNEY TEAM to have your back ( I AM A BENIFICIARY) this is WHO YOU NEED.... THANKS GUYS

Konstantine Outstanding Gifted Lawyer and Person

From the moment I emailed Konstantine about Conservatorship issues, his response back was immediate, and I felt a ton of bricks lifted off my shoulders, by the confidence, intelligence, and kindness he portrayed in taking my case. The trust you feel with Konstantine is immeasurably. He always has yo...ur goals and best interest in mind. He is extremely laser focused, and gets to the point. He has been incredible throughout this whole process, adding his humor to an already stressful situation. Konstantine by far is a remarkably cultivated, highly skilled, well educated accomplished lawyer that you want for your case. He knows the Probate Laws, Elder Abuse, etc., and is a highly skilled litigator. I will use Konstantine over and over again. Great lawyers own their clients problem and engender a belief that they will do everything possible to help the client succeed, and Konstantine does just that. Konstantine genuinely cares about you and your case, and is extremely hard working, and professional. It’s amazing to find so many genuine qualities in one person. I will always be grateful for how he’s helped me. I would highly recommend him to anyone!

Konstantine has a lot of wisdom on how to win a case

My family found Konstantine’s law firm through a Friend. He’s knowledgeable... as a matter of fact I was going to let something go of value. I didn’t want to go through anymore. But Konstantine and his team took care of the matter. And my family won in court . I thankful to them ! I’m glad I listened... to his wisdom. Now, my children and I can rest.. because it over. Thank you Lisa

Mr. Kosta Demiris

I am writing this recommendation in regards to Mr. Kosta Demiris who represented my wife in a civil litigation case recently involving the settlement of her father’s estate. Over the past 9+ months Mr. Demiris has been the consummate professional, hardworking, dedicated, and most importantly has his... client’s best interest at heart. Mr. Demiris controlled demeanor, confidence, and his wealth of legal knowledge regarding our case is to be commended. His strategy with our case was spot on and there is no doubt the very positive outcome we received would not have been possible without the formidable talents of Mr. Kosta Demiris. With that said, I highly recommend Mr.Demiris. If you are looking for legal consul to represent you and your best interests there is no better attorney than Mr. Demiris.

Relationship: Friend

"Konstantine is one of the best probate litigation attorneys I know. He is also extremely well versed in all aspects of elder law. He is one of my go to colleagues when I have an elder law issue and have referred him cases in the past. Each one has come back with positive feedback. I would not hesitate to recommend him in the future. He's a great attorney who is passionate about the community (he volunteers with elders at care homes), the legal community (a former member of the Inn of Court), and really takes care of his clients. I strongly recommend him."

"I have known Kosta for over 5 years. We have worked together on several county bar projects and I have referred several individuals and other attorneys to him. On the projects that we have worked on, I am impressed with his diligence and effort to help get the project completed. Individuals who I have referred to Kosta have all told me that they were happy with him."

Elder law lawyer | Jul 23

Relationship: Opposing Counsel on matter

"I've known Konstantine "Kosta" Demiris for many years in the local Contra Costa elder law lawyer community. I have litigated matters against him, but also worked on complex family cases with him. Elder law cases are rarely black and white and he is quickly able to grasp the nuances of each case. I have enjoyed working with/against him on matters, because he is a straight-forward, hard-working attorney who moves matters forward quickly. Even when he represents a party directly opposite to yours, he does so with professionalism and respect. He is good at communication and help facilitate communication between warring parties. He also represents professional fiduciaries, so I often contact him to see if we can work with one of his clients on complex matters. If a family is unable to work together, it can sometimes make sense to bring in a neutral third party to administer the matter. Kosta assists with the legal process there."
