The team was very professional and competent. They have been very responsive and accessible, and have always kept me fully informed about the status of my case. They did excellent work regarding the mediation process, and now regarding the legal issues related to the sale of my property.

Ezra Makori has a very personable and friendly style and approach which I greatly appreciated, as it enhanced our ability to communicate effectively, particularly during the mediation process. I was always very impressed with the legal expertise which Mr Makori demonstrated while dealing with my case, and the valuable advice he offered me.
