One tough situation

Mr. Demiris showed his professionalism, and concise plan for getting the job done. Attorneys I consulted with all pointed me to Konstantine as they saw this case was not in their level. It required an expert in this field. I highly recommend to anyone that have an issue with a will/trust to have him ...in your corner.

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 Demiris Recommendation

Konstantine Demiris has been my litigator for a family trust dispute. It was one of the most auspicious days of my life when he agreed to defend me. The dispute involved contentious family members, an aging mother who died before the dispute was resolved, and a plethora of complicated conservator a...nd trust issues. Kosta is well-educated; he attended the University of California at Berkeley and the University of Santa Clara Law School. He is a consummate professional and has in depth knowledge of probate law and the workings of the courtroom. Kosta is always prepared to do research in the event of mind boggling issues for their legal resolutions. Kosta is personable and compassionate. He kept me informed of my ongoing case events without adding to my anxiety. We exchanged emails frequently and had phone conferences as needed. He has a wonderful sense of humor and that helped me survive this ordeal. The litigation involved an entanglement of assorted attorneys and petitions which Kosta unraveled with acumen. He was my North Star in troubled waters. Kosta is reasonable and fair with his fees. He deserves every penny. I highly recommend Konstantine Demiris for anyone’s defense in any probate court action.

Elder Abuse Case- Highly Recommended-Very knowledgable, straight-forward and supportative

Kosta was and continues to be excellent as my attorney in an elder abuse and conservatory case. He's been very thoughtful in explaining the process, expectations and challenges with such a case including undertakings and costs. With a case that is very challenging and tasking both through the proces...s and emotionally to affected parties (conservativee and petitioner) involved, he was very supportative, went to task for you and walk you through each of the stages performed. from the many questions I had at all hours on the process to the challenges with the evolving situations, Kosta handled them swiftly, professionally and kindly. Kosta was highlyrecommended by several attorneys that I has consulted with and most importantly that he specialized in such elder abuse cases. The process has been lengthy and challenging, I have always felt truly confident in my selection of Kosta as my attorney. He successfully won the case in which the conservatees are now safe and secure -which I'm truly thankful for every day.

Great and honest attorney

Konstantine was referred to our family by our family attorney Richard Lee and what a blessing for us. Our family was struggling with a very ill father and providing proper care for him required conservatorship of his person and estate. My mom and I didn't even know what a conservatorship was but Kons...tantine made it simple and easy to understand. He explained every step of the process and time was of the essence and he didn't lag. He kept pushing the process through courts and got it done. I know it's impossible to believe all attorneys are hones and fair but Konstantine is the Michael Finney of attorneys. He is always on your side. Great guy.

"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."
