Testimonials
“Catherine Demers is an amazing attorney! I didn't want someone just representing me but someone that would actually fight for me! She went the extra miles for me and did just that! While on parole in 2 states, I caught charges in four counties and 2 states. She managed to keep my parole active and not violated for me to not go back to prison! She was also able to convince all the prosecutors involved to give me a final chance with rehabilitation and not just another prison sentence! By the grace of God and an amazing attorney I am progressing successfully in my drug program and life because of the amazing job she was able to do as an attorney! I am forever grateful for everything she has done for me! All the troubles I have had in my life, she is by far the best attorney I have ever had! Not only an amazing lawyer, she has become a wonderful friend! Highly recommend her to anyone needing counsel!"
