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...

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...

Thank You Kosta
I’m sure my father had no idea how hard it would be to be executor of his estate. I think we all think when we saw other families falling apart over inheritances that it could never happen to us. My father’s wishes were so simple and fair but from the beginning challenged. I was told by others to exp...
"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."
"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."
"Konstantine "Kosta" Demiris, of Demiris & Moore, is as savvy as they come and he will work tirelessly to obtain the best result achievable for his clients. If you are anywhere in the Bay Area and have a Will, Trust & Estates, or Family Law matter, you owe it to yourself to have a consultation with the firm of Demiris & Moore. They are fearless advocates for their clients and are highly respected in the legal community."
