Jennifer LaCoste's Lawyer Endorsements
"Ms. Lacoste is always composed, professional, and diligent in her work as a family law attorney. She is compassionate to her clients, always seeking the best outcome for them. Further, she sees clients as people who need her help, not as customers."
"I've known Jennifer for many years, and I've watched her become the attorney she is today - smart and tough, but with compassion for her clients. That's really what one should want in a family law attorney. I endorse this lawyer."
"Jennifer is a hard working, effective advocate for her clients. She provides valuable advice and counsel to those she represents, and is an excellent attorney."
"I am happy to endorse this lawyer. Jennifer is intelligent and caring. She takes great care with her client's cases, such that I would not hesitate to recommend her services to my own family or friends."
"I endorse this lawyer. Jennifer is a great mix of high level legal intelligence and real life pragmatic problem solving ability. She is uniquely suited to help her clients get excellent results."
"I'll just say, I'm glad she works for us (Ashby Law). There is no one in the Tri-Cities whom I'd rather have on my side at trial. Jenn does not back down and zealously represents her clients."
"Jennifer is one of Benton-Franklin Counties leading practitioners. It's obvious how much respect she commands from the local bench and bar. What is less obvious is how much she gives back to the bar and the community in service. A first rate attorney and person."
"I endorse this lawyer."
"Jennifer is committed to her work in family law and to her clients. She is highly motivated and advocates well, having had excellent trial and collaborative law training. I highly endorse Jennifer LaCoste."
"Jennifer is an excellent attorney and is extremely dedicated to her clients. She has extensive family law experience and truly enjoys her career. She never fails to take the time to answer questions. She is available not only to her clients but also her colleagues. Jennifer is professional and knowledgeable and I am proud to endorse her."
"Jennifer is an amazingly well-prepared, passionate, and intelligent attorney. She is strong, confident, and poised in the courtroom and for her clients. I have no hesitation in endorsing Jennifer as an excellent Family Law attorney."
"I have worked against Ms. LaCoste on two child custody matters, and in each case we worked under difficult circumstances but managed to productively reach resolution. She is a staunch advocate for her clients, but I also found her to be very approachable and reasonable. I endorse this lawyer."
"Jennifer is an amazing lawyer who cares deeply about her clients. She is a competent and skilled attorney!"
"Jennifer is a skilled legal professional. She is a great advocate for her clients."
"I am impressed with Jennifer's work ethic and drive to achieve her client's goals. I endorse this lawyer."
"I endorse this lawyer. She is intelligent, hard working, organized, and compassionate."
"Jennifer is thorough and relentless in protecting her client's interests. I endorse this lawyer."
"I endorse this lawyer."
"Jennifer and I have opposed each other in a number of cases but only recently had to take a matter to Trial. It was nice to be able to work on focusing on the issues for a Trial instead of purposely delaying or frustrate the process. I believe it says something when you can respect the lawyer on the opposing side at the end of litigation; I would recommend her as counsel for family law issues."
"I endorse this lawyer. She works hard for her clients. She cares about them greatly, and will do a fantastic job for them. If you want a lawyer that listens to you, works hard for you, and cares about your success, go with Jennifer."
