  The last two years have been tough for me because I have been faced with three criminal cases. I am glad that I found Mr. Garet Holland and his associates, who provided legal services for my cases. I am very thankful for this incredible service, resulting in all three of my cases being dismissed. Mr. Holland, I will never forget how much your service meant to me. Sincere thanks, Val Melnikov

  My first experience with Cannon & Associates in 2021 went extremely well, which is why I returned. Unfortunately, my current experience has been very different. Communication has been inconsistent, response times have often been slow, and I have struggled to get timely updates regarding important matters related to my case and property concerns. During a stressful legal situation, clear communication and responsiveness are extremely important, and I do not feel my expectations in those areas were met this time around.

  Haley Mock and her assistant, Laurie, did a wonderful job with my divorce. They were very efficient, knowledgeable and have great communication skills. Haley is very quick to respond to emails. I prayed for the right lawyer and that is exactly what I got. She always made me feel taken care of and was quick to fight for me. I cannot recommend her enough!

  If you are looking for a lawyer who is not only knowledgeable and professional, but also considerate and truly listens, I highly recommend Attorney Garet Holland. My son is not even from Oklahoma. He is a native of Louisiana and had only been living in Oklahoma for a short time when he got into a little trouble. Being from another state and not knowing who to trust made the situation even more stressful for us. We spoke with multiple lawyers before finding Garet, but what stood out to me was the communication, his patience, and the fact that he really cares. Me and my son both were concerned about his future because the goal was never to just get through a case, the goal was for my son to still have the opportunity to succeed in life afterward. He listened to everything we said, took our concerns seriously, stayed in communication with us, and handled everything so smoothly from beginning to end. What meant the most to me was that he showed compassion and grace. In today's world, it matters. He did not just treat my son like another case file or another number. Even though my son was not from Oklahoma, he still fought for him, stayed loyal to helping him, and truly wanted the best outcome possible for everyone involved. Everything we discussed and hoped for, he executed it better than we expected. He is hardworking and punctual and that makes all the difference. I truly believe he deserves advancement and a lot of recognition because people like him are exactly who families need during difficult times. Thank you again to Attorney Garet Holland for helping my son and treating us with kindness and respect through the entire process, you are the best!!!

  Haley was amazing, keeping us updated every step of the way and answering our questions even when she was busy. The attorneys were helpful, supportive, and everyone at the firm explained their roles and the process from start to finish. I never once wondered if they had our back or were on our side

  ⭐⭐⭐⭐⭐ I can't thank my lawyer team enough for the incredible work they did on my case. From the very beginning, they were professional, responsive, knowledgeable, and genuinely committed to helping me get the best possible outcome. They kept me informed throughout the entire process, answered all of my questions, and made a very stressful situation much easier to deal with. Thanks to their hard work, dedication, and expertise, my case was ultimately dropped — and I truly believe I had the best team fighting for me. I'm beyond grateful for everything they did and would highly recommend them to anyone looking for a legal team that truly cares and gets results.

His confidence, attention to detail, and courtroom presence gave me peace of mind during a difficult time.
