Client Testimonials

Client

★★★★★

Sarah Smith is an attorney that doesn't just set herself apart from other attorneys with her knowledge and skill, but with a compassion not only for the law but the client. I have never had a relationship with a lawyer that I considered an actual relationship. A working relationship with confidence and an infallible trust that my best interest was and is at the for front of the decisions being made on my behalf. Sarah has always taken the time to get to know me and the situations to understand the decisions that need to be made, while possessing compassion and professionalism throughout the process. I can truly say that with her as my attorney the person I am, and will continue to become is a direct reflection of her ability to see in others what we can't see for ourselves, and convey that hope in a court setting that isn't always compassionate. I owe my life as it has become to her and I am forever grateful.

. Joe Costner and his staff are absolutely amazing. From the moment you walk in, his front desk clerk makes you feel welcome and taken care of -- she's kind, professional, and always on top of things. Mr. Costner himself is knowledgeable, easy to talk to, and genuinely cares about his clients. He explains everything clearly and takes the time to make sure you understand what's going on. You don't feel like just another case here -- you feel respected and in good hands. Highly recommend this office to anyone who wants honest, professional legal help.

Highly Recommend - Outstanding Criminal Defense Attorney Attorney Sarah Smith is an exceptional criminal defense attorney. She took my case seriously from day one and refused to settle for anything less than the best outcome. Thanks to her hard work and determination, she was able to reduce the severity of the charges against me, avoid probation entirely, and get the case expunged from my record immediately following my final court date. She's smart, compassionate, and truly fights for her clients. I'm beyond grateful for everything she did!

To whom it may concern, Sarah Smith became my lawyer on August 4, 2025. The first time we met she made me feel very comfortable, and I knew I could trust her. This was the first time I've ever needed a lawyer, so didn't know how all of this worked. Sarah was very patient and helpful with my many questions and concerns. With her professional help and advice, today, September 11, 2025, was our last day in court together, as all of my charges were dropped, my GPS monitor was removed, and I'm now free to go home. Sarah is an incredible lawyer, I would highly recommend her to anyone. Sincerely, Cathryn Francez Samson

It was awesome, very professional and cordial. They treated me like I was a friend and that means a lot when you're in this kind of situation. I have used Costner green before but Sarah is great. She helped me a lot, explained everything. And thank you so much.
