    What Customers Love

    I’m incredibly grateful for the support and representation I received from Alyssa Phillips during my custody case. From day one, she was professional, compassionate, and fully prepared. She took the time to explain the process clearly, answered my questions promptly, and made sure I felt confident every step of the way. Most importantly, she genuinely cared about protecting my children's best interests. It was a very emotional situation for me, and she remained calm, strategic, and strong in advocating for my family. I highly recommend Alyssa Phillips to anyone facing a custody matter.

    Ryan Shepard, Google Review

    I hired Mark and worked with him for a little over a year on my case. I had a good experience with him and the staff. He’s very informative and knowledgeable with the law and court system. He has a great reputation in this area. He was recommended to me and I am glad I trusted him with my case. Long story short he got me the best possible outcome in my scenario.

    Diana, Google Review

    I can not recommend Mr. Williams and his associates enough! From the very first consultation, they were professional and knowledgeable. They took time to explain every step of the process and made sure we felt confident with the whole situation. His entire office staff were always kind and compassionate (even with my millions of questions lol). I hope to never have to seek his services again...but if we ever need a lawyer in the future, Mr. William will be our first call!

    Misty Overhulser, Google Review

    Extremely please with Mark B. Williams & Associates!! I made the call and he helped me navigate on what needed to be completed. My stress level reduced as soon as I spoke with Mark. If I ever need a lawyer in the future, he will be my go to!! Wish I could give 10 Stars!! Highly recommend!!

    Heidi Corbin, Google Review

    I was lucky enough to have Alyssa Phillips work with me on my divorce proceedings. She was awesome! Very knowledgeable, friendly, smart, and always prompt with communication. She was always looking to do what was in my best interest and not looking to just try to make money. We were able to settle outside of court and she was even able to refund a very fair portion of the retainer fee. Very highly recommend! Thank you.
