Demiris Law Firm

I rarely give reviews. And particularly only when they were well deserved, hence the five star rating. The tandem of Kosta and Michael of the Demiris Law Firm worked beautifully together like a symphony of heavy metal music on a recent case we entrusted them with. The case was very emotional for us, as it was related to family members that we cared a great deal about. These two took the time to understand our concerns about what was being done on the other end and fought tooth and nail for us along the way towards what was a reasonable settlement on our behalf. If you are looking for silver tongued, meek, smooth talking attorneys in $3000 designer suits who will tell you what you wanna hear...these are not the guys for you! They will be brutally honest. They will tell you the positives and negatives about your case, talk openly about potential success, be straightforward and genuinely concerned with your particular situation. Most importantly, they will work on your behalf like a hungry pit bull does on a t-bone steak to get you what you deserve. Give them a call!

Highly recommend Kosta and his team. He was recommended by a friend and another lawyer. From first contact I felt more at ease knowing he would be on my side. I could tell he was the fighter I needed. I was taken out of my Grandparents trust by my malicious Aunt. Kosta explained all my options and was not pushy about which one I ultimately decided would be best for me. I opted for possible mediation that could lead to a court case. To my huge relief Kosta’s savvy arguments and determination was able to help me get my fair share of the trust. Kosta responded very quickly to my emails and calls. He was always patient with me. I’m very happy with the outcome.

My brother hired Kosta Demiris. Sadly two days into trial he bailed after my brother took out 2 or 3 loans on his house, his girlfriend took an advance in alimony pmts and took from her Ira and it still wasn't enough. He was hounded for more money seemed like daily. My sister if u can call her that, more like the devil, got to keep everything she had stolen, ruined relationships, responsible for infecting my mother with covid, abandoning my father after electronically transferring money she should not have done and after purchasing a 970k condo she abandoned him and flew back to New York to enjoy her rewards she worked diligently to get. I dont think he did enough in the beginning to stop her from being able to use trust funds for her defence and to burificate the case was a huge loss. To get to a point where u can finally get justice at ur fingertips to have it all thrown away is mind blowing. Kosta kept telling him u need this much more money and some how he would find it only to be told its 10k a day for trial and then if u win this part then u need to prove undue influence and it would be god only knows how much more. In the end my brother got squashed and so did I. I told my brother to get rid of the arraogant jerk but he didnt listen. They accomplished absolutly nothing. My brother is selling his house on 41 acres and has bought a fifth wheel to live in. Way to go!

I hired Mr Demiris out of necessity. I am an individual with a disability that was being taken advantage of, and legally bullied by a disgruntled sibling and their legal team. I needed protection! As soon as Mr. Konstantine Demiris stepped into the ring he not only protected me, he brought the fight to the opposition! He immediately stopped the bullying and changed the fight questioning my siblings lawsuit, calling it "frivolous", then legally forced them to quit! He was extremely compassionate twords my situation, and regularly checked on my well being during this legal battle! If you have a disability, need protection, or need friendly honest legal advice! This man is the answer!

I highly recommend the Demiris Law Firm. This firm just won a critical third-party conservatorship case for my mother, which will put an end to all the family’s elder abuse inflicted upon my 84-year old mother for at least the past four years. I am so grateful. I am fortunate in hiring the Demiris Law Firm that has successfully won my difficult case, which will allow my dear mother to finally be shielded from all the family abuse. Now with a third-party conservator in charge, mom and I can finally have peace to enjoy quality mom and son time. Life changing! I am forever grateful! Staying as a client.

Knowledge, professionalism, amazing help personally from Mr. Demiris. The place to solve your problems with wills and trusts.

Don't waste your time if your "pot" isn't big/deep for him. Shows again what is the real drive behind.

I cannot say enough about the tremendous job Mr. Demiris did for me He is THE ABSOLUTE BEST in his chosen area of practice. Mr. Demiris is an extremally knowledgeable and tenacious Attorney that was always available at any time, was reasonable in his fees, always upfront and transparent with me and always always had my best interests at heart. My case was sensitive and stressful to me and he and his team took excellent care of me throughout the process and the win! He made it possible to hold those accountable for awful things and to deliver justice for my parents. I highly recommend Mr. Demiris and his team for all of your needs in their areas of expertise. A huge thank you also to Mr. Schreiber for all your hard work as well. So Grateful to you all

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.

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.
