My main focus as an attorney is to focus on my clients' needs.  I believe that their needs is of upmost importance in any type of case.  To be successful, there must be a high level of trust.  Regardless of the case, my clients are trusting me with something that is extremely important to them whether that is their money, their children, or in some cases their lives and freedom.  I have a passion for my career and treat every case with the individualized attention that it deserves.  Additionally, I understand that legal matters can be extremely expensive and that is why I believe fair billing practices are important.

Excellent lawyer to have working on your case
I hired MacKenzie Grills about a year into my custody case due to my previous lawyer having some difficulties with the manner of the case. MacKenzie provided a very detailed and in depth free consultation, and after I had the consultation with her, I knew she would be able to work with me and the situations of my case. She provided a lot of knowledge and insight with her experiences to handle my case. MacKenzie has been doing a good job of keeping me abreast of information regarding my case, and she responds quickly and in a timely manner anytime that I have had questions, concerns or incidents that have occurred during my case. MacKenzie can be tough and aggressive when finding, stating and maintaining facts of the case, but proceeds in a professional manner. MacKenzie has been there for my family and me during this difficult custody process and I would highly recommend her for your legal commitments.

I hired MacKenzie Grills to represent me in a custody case. I had first consulted with her and was worried being a father that I wouldn't get much time. She was very honest about my situations. She told me what I could get the first time around and that is what I got. A few years later, my children expressed wanting more time with me. She told me the worst that would happen is the order would remain the same. She said best thing that would happen is I would get more time with them. We had a custody trail and I was given more time with my children. She was amazing in the courtroom. She stuck to the facts when presenting my case to the Judge. As an attorney, she did not do things or allow me to ask her to file things that would just be a waste of money or time. The last hearing I had was a Motion for Contempt filed against me. She represented me again with truth and facts and the Motion was denied. Everything with my case that she said would happen did happen. Her compassion towards family law and people she represents is amazing. At my last hearing, my children came running over to give me hugs. I noticed the smile on her face when they did this and really realized how much she loves doing what she does. I would highly recommend Attorney MacKenzie Grills and I have to friends.

The best lawyer to have on your team
I had to change lawyers in the middle of a divorce due to lack of my previous lawyer lack of "understanding" my situation. I met MacKenzie through a referral and she hands down was an angel sent!! Made the transition smooth, she didn't drag my case out, and def. worked in the interest of her client!! I won't ever deal with a different lawyer again!!! Trust me she is def a must have on your team!!

Would definately recommend Attorney Grills
Attorney Grills was very knowledgeable and attentive. She made a very difficult process easier and less stressful from the consultation through the end. She was upfront and honest from the beginning about options and what would most likely happen during the process. Definately would recommend.

MacKenzie took the time with me to explain everything and was very thorough in handling my case. She returned calls and and showed genuine concern in my case. I would recommend her and DeRiso, DeRiso & Suher to all the people I know who need a lawyer.
