    I endorse this lawyer. We worked on a case together with very high conflict issues where Ms. Jensen represented the children. Her investigation was extremely detailed, and she worked very hard to make sure the children were protected and advocated for their best interests. In the end, she helped shorten the litigation time to a fraction of what it could have been. She is very professional and her years of experience are a great asset.
