| Hired Attorney
100% Untrustworthy
I really want you to keep this in mind when considering hiring Breanna Slattery DeBritton. If Breanna Slattery is willing to do this to a paid client and a fellow attorney, imagine what she'd do to you! I am an attorney. My father and I hired Breanna Slattery to create a simply trust on behalf of my Father. Worst mistake ever. Breanna was paid 100% up-front Cash. She came by, picked up the money, had my Dad fill out some paperwork, and essentially disappeared. About 6 months after my dad hired her, my Dad calls me and asks me why Breanna hasn't returned his calls or emails and when could he expect the trust to be done. I immediately called Breanna, she apologized and promised to immediately call my dad. A month goes by. My dad comes and asks about Breanna again. i ask him "didn't she call you, she promised me she would" - my dad says he hasn't heard a word from her. I call Breanna. She again promises to call him. Another month goes by.. I email her again.. she still hadn't contacted my Dad. LONG STORY SHORT, OVER A YEAR GOES BY. My Dad wasn't contacted or called AT ALL during this period. Breanna promises and promises me to my face and promises but never calls him. AFTER A YEAR OF THIS CALLING WEEK AFTER WEEK, MONTH AFTER MONTH - ALL OF WHICH I CAN PROVE, I SEND BREANNA A DISENGAGE LETTER, and had to hire an new attorney for my Dad's trust. We demanded a refund. To this day, Breanna NEVER called my dad and never gave us a refund of the retainer fee paid. In my opinion, THIS IS DISHONESTY. She took money for work she never completed and she never COMPLETED the trust. So- let's talk about the other people someone I referred to Breanna. Let's put it this way - One day I get a call out of the blue from a woman I referred Breanna. She wants an "Emergency" meeting with me. I agree. When we meet, the VERY FIRST WORDS out of her mouth were "Is Breanna Dead" - Utterly shocked, I answered "Excuse me?" - Apparently after months of calling and emailing Breanna without any response, this woman thought Breanna to be dead. I'm not kidding. This really happened and in all the years I've been involved in the legal field, I have never experienced anything like Breanna. Breanna Slattery LOVES money, and distains her clients, my father included. My father was a great man. A man who devoted his life to the welfare of disabled children. Had a Phd, and was calm, polite at all times, and quiet. and once she got the money, she treated us like less than dirt.
