    Derek handled my case with care, respect and professionalism. He is knowledgeable and always had a grasp on where my case was. I could tell he worked very hard to give me the best outcome possible. And I was very happy with my outcome. Thank you Derek. Your hard work and professionalism did not go unnoticed. You will be highly recommended by me to anyone in need of your services.




    Derek was very helpful giving great advice that I needed. He was very knowledgeable and presented everything in a way I could easily understand. Many thanks to Derek for a favorable outcome.




    Derek helped my family and I through a tough time recently. He was able to get things settled with the opposing counsel in a timely manner and let us get started on our new journey.




    I'm very lucky to have found Derek Byrne. Anyone familiar with a broken home has heard endless tales of battles within the court system. Derek manages my time and money extremely well. He is accurate in his expectations, patient with my inquiries, and above all, puts my child's needs before everything.




    Mr. Mallory represented me with some very sensitive depositions. He was always professional, knowledgeable and steered me in the right direction. He was prompt in returning calls and I always felt that my best interest was his best interest.




    I came to Drew with a legal issue that was very important. He guided me through the process and I am very happy with the results. I found his advice to be reassuring and his representation gave me peace of mind. Thank you, Drew.
