They were awsome for me. It was at a time when they were very busy and could not handle my case properly so they gave me a check for every penny i had paid them and did not charge me a dime for all their attorney time spend. Something i have never seen a law firm do.

Helpful, professional, and quick with answers.
I've reached out to Katherine on numerous occasions, and I always feel like she's had plenty of time to give me real human responses. I miss that in today's world. She not only helps with legal counsel, but gives you ideas that you can work on yourself in your own time to fix whatever problem is bothering you. Hope this helps with your choice of a great attorney!

Employment Discrimination Case
I can't say enough about my attorney, Brice Bisel. He handled my case with expediency and was extremely professional and attentive at all times. My questions were always answered promptly within 24 - 48 hours, his advice was always solid, and I was never made to feel that my questions were unintelligent. Brice believed in me and had confidence in my case, and his supportive attitude helped me through a very stressful situation right to the end. Mazaheri is a small law firm with a wide field of expertise, and you will never feel like you're lost in a sea of ever-changing attorneys. Highly recommend Mazaheri Law Firm without a second thought.

Absolute Best!!!!
Brice Bisel of this firm has been my ROCK. He has always been proactive in my interest, and very professional, yet personable and respectful. I HAVE THE UTMOST RESPECT FOR HIM. The attorneys at this firm are very knowledgeable about multiple and numerous areas of law. They always respond in a very timely manner, and never leave you wondering. Katherine Mazaheri is also an attorney with foresight and compassion. I believe she saw the need for a law firm that rates 5 STARS, and thus assembled this group of attorneys to meet that need. I hope to see this firm grow, which I have no doubt will happen. BEST EXPERIENCE EVER WITH A LAW FIRM!!! Highly recommended by me!!! RHH

Karla- Divorce and Child Custody
I had Ann as my personal attorney at the Mazaheri Law Firm and I will definitely use her again in the future. She was thorough, always there to answer my questions via e-mail, telephone or in person. She did a great job of keeping me up to date and I didn't just feel like another client, I felt like a person and she really cared about my needs. I would definitely recommend this law firm to anyone. My dad also used them for a Trust and Will and the service was fast and easy and he was pleased as well!

Ann Zachariah
Ann Zachariah was a great help through all the troubles and problems. She was quite knowledgeable about the proper channels to go to accomplish the goals we had set out to achieve. When she did not know the answer she would do the research to find the correct answers. She kept us up to date on everything she did and was going to do and always told us as soon as possible when changes occurred.

Excellent Law Firm for Divorce
I was impressed with the way my case was handled at this law firm. I had dreaded the process of obtaining a divorce and they made the process very simple. All charges were explained in detail up front and I did not have any unpleasant surprises along the way. I was most impressed with the personal phone calls and emails that kept me up to date on any changes in my case. Any time I called with a question my phone call was returned timely. Ann and Dani were always very kind and respectful. I would recommend them to anyone in the difficult circumstance of seeking a divorce.

Mazaheri Law Firm work to support homeowner claim against City of Moore
Mazaheri Law Firm support has been absolutely essential in my case. Extensive experience and research have allowed me to face a difficult and overpowering opponent in court. Each stage of the court case has been carefully and fully discussed and explained to me in terms I can understand. The use of expert witnesses and documents shows the experience and expert knowledge provided to me by the firm's lawyers. The only difficulty I have had so far is some bookkeeping issues which were quickly resolved to my satisfaction. I strongly recommend this firm to anyone needing a lawyer.

Honest, Helpful, and really looking out for me
I contacted Mazaheri Law Firm when I had an issue with my now former employer. Katherine Mazaheri handled my case. When we first met, she made me feel she was trustworthy, gave me honest feedback on the issue, clarified the legality of the issue which I had not fully understood, and helped me win my case. I would highly recommend using Katherine in the future.

wonderful group of people!
YES i would recommend this attorney and i HAVE. we had a very HUGE/stressful case on our terminate the rights of my son's bio father and let my husband who has played the father figure the past 4+ years adopt him. when your child's future is on the line and you have to hand it over, put it in another persons hands that is a stress/worry i can't describe. but katherine made it soooo much LESS worrisome then i had thought it would be. she knew her facts, she kept us up to date, and she always answered any question we had in a very quick manner. after speaking w/ katherine i had a sense of peace, she had all her ducks in a row and it SHOWED the work she put into our case. in the end we won and that has improved and changed our lives tramendously! if there is every a need for us to use an attorney again we will not hesistate to give this firm a call.
