Best Family Attorney

"Diane is a highly skilled attorney who combines professional excellence with a compassionate approach. She is deeply committed to achieving the best possible outcome for her clients and provides essential emotional support during the stresses of the court process. She treats you with a level of care... that goes beyond a typical professional relationship, making you feel like family. I have hired Diane twice and have referred several friends and family members to her, all of whom have seen great results. I highly recommend her services."

LOOK NO MORE!

I cannot recommend my attorney highly enough. From the very beginning, she treated me with kindness, respect, and genuine care. She took the time to explain every step of the legal process, answered all of my questions, and made sure I always felt informed and supported. What impressed me the most w...as her professionalism, attention to detail, and dedication to my case. She fought for my best interests, stayed prepared, and communicated with honesty and integrity throughout the entire process. During a stressful time, she gave me confidence and peace of mind because I knew I had someone who truly cared about achieving the best possible outcome. If you are looking for an attorney who is knowledgeable, compassionate, responsive, and willing to go above and beyond for her clients, I wholeheartedly recommend her. I am incredibly grateful for everything she has done for me and my family. Thank you for your outstanding representation and unwavering commitment. You are truly exceptional.

Caring and compassionate and such a great team!

I feel comfortable with Diane's office after consulted with other attorneys. I got her contact through friend, friend and someone that lost case to Diane's office. Diane and her team were sensitive to my need and emotion. Answered questions that may have seemed petty with respect and dignity. Th...ey working tirelessly to ensure the best possible outcome on my behalf, and I can't thank you enough to Diane, Sara and Annie. I recommend to anyone. God Bless You Ladies

I'd re-hire her in a heartbeat.

I hired Ms. Hartog to represent me in my divorce. I can honestly say that it is a shame she does not practice more areas of the law because I would prefer to have her team handle all of my affairs. She is fair and honest, and her fees are very reasonable. I have felt very comfortable with her and ...with her staff as they have all gone above and beyond to handle my case with care. After having read the last two reviews, I can hardly believe they were talking about the same attorney, as this was exactly the opposite experience I had when represented by Ms. Hartog. I make it a point to refer all of my friends, family and acquaintances to her if they happen to need a lawyer who handles family law. And the feedback I get from them is the same satisfaction that I have had in dealing with her firm.

She starts off great but once you get to know her run

When I first met Diane I felt very good about her taking my case and getting it cleaned up. But in the long run she only got me supervised visits thousands of dollars later. I could have done that myself for free. She cares only about money and if you are late with a very small bill be prepared becau...se she will ask you to sign a release. Don't bother giving her good information to use for your case either because she will not use it for the judge to see. I had one job for her and that was to make sure my girls were safe from there abusive father. Now she asked me to release her and didn't even notify me I had a court date and will not give me my file to prepare for my court date on my own.

Replied last June 02, 2016

The file was ready within the week and has since been picked up. It is unfortunate that this negative review is a result of the client not honoring their contract. This client told me in no uncertain terms that they would be leaving a negative review as soon as they figured out how. The way this review is written makes it appear as though this client is on monitored and supervised visitation; which is not the case. This client was put in a position of strength, a position they are still in. As is typical with many clients who fail to honor their contract and are reminded of their obligation, the complaints about “nothing being done” are tossed around. I do care about the children and I wish this client all the best.
