He saw us thru a very difficult family situation with an excellent result. In addition he is a gentlemen a nice man. I highly recommend him.
Sincerely, A very satisfied client.

I came to Kosta after spending about $100,000 on another lawyer just to get a TRO against my brother and his entourage who were abusing my father. In a fraction of the time and for a small percentage of what I paid before, Kosta and his associate, Michael Neeham got me temporary conservatorship!

After sitting down with Kosta one of the first things that will strike you is his intense drive to do what's right; his passion for doing good on behalf of his clients and their families is readily apparent. He is knowledgeable, driven and ready to listen. The rise of Elder Abuse and Elder Fraud in society has risen to epidemic proportions, so finding a specialist like him to fight to right the wrongs perpetrated on such a vulnerable part of society is amazing. If you know someone who's senior parent has been taken advantage of in any way, I have no hesitation recommending you contact the lawyers at The Demiris Law Firm.

Just met with Kosta and have referred him in confidence that he cares about his clients. He fights for his clients and his greatest reward is doing a great job for clients who have been wronged, and generally from family members. Spending time with Kosta you can see right away he acts with integrity and honesty.

Mr. Kostantine Demiris is very intelligent, knowledgeable, and precise in his approach, as an attorney. Having him alongside as my lawyer, has so far been one of the best choices I have made. Mr. Kosta went above, beyond and out of his way, in representing me.

First, his legal writing is concise and very clear and second, his cross exam skills in the court room is just great. I am very impressed by his presentation skills. He effectively argued our case and won it for us! 

Mr. Kosta took on another tough case for us and in the trial, it was clear how thoroughly he had prepared. He provided strong presentation in the courtroom. He won the judge's respect and made our case convincingly. Mr. Kosta won both my case !!!  HE IS THE BEST PROBATE/ESTATE ATTORNEY IN THE BAY AREA.

I highly recommend Mr. Kostantine to anyone in need of a conservatorship lawyer for his expertise.

The best lawyer when it comes to family law. He’s very respectful and very thoughtful. He has an awesome crew who worked tirelessly to help my family’s concerns. He’s an honest lawyer who doesn’t give false assurances. I’m truly grateful for having Atty Demiris and his group of great lawyers to represent my family

During my research to find help with an elder abuse situation, three different agencies recommended that I call Konstantine Demiris at Demiris Law Firm. I was not disappointed in the least. I can’t thank Kosta and Constance enough for their quick response and hard work toward achieving the best possible outcome. Their professionalism, focus and calm nature is truly admirable. If you need a professional in elder law, I highly recommend that you call them.

The best!

Peace of mind attorney

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 and 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.

Kosta is my current attorney. He is truly an amazing attorney. He's been doing exceptional work for seniors who were in abusive situation. Kosta is sharp, precise, on point and professional. I was helping seniors who were abused by their own conservator. The former conservator took seniors' money and changed their will and trust to inherit their estate. It was a very difficult case, but Kosta worked day and night to remove the abusive conservator and did extraordinary work. As a result the judge ordered to suspend the abusive conservator. I would recommend Kosta to anyone and everyone especially if you are in a difficult and abusive situation.
It looks like the abusive conservator who lost the case posted false incident that never happened with Kosta. If Kosta was 'unprepared' as the abusive conservator's fake review stated, why is he suspended? I am thankful he is gone. Kosta is a great attorney with high integrity. He is the best attorney I've ever known.

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. Kostas 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.
