More Than an Attorney—A Trusted Advocate

Ms. Hartog is a true advocate for both children and her clients. She fight tirelessly for the best interests of children while recognizing the emotional toll divorce can take on families. Her compassion, support, and dedication make clients feel heard, understood, and cared for throughout the entire ...process. Anyone looking for an attorney who combines fierce advocacy with genuine empathy will be in excellent hands!!

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.

Be Aware

BE AWARE I went to see Diane about a family law matter paid her 250.00 for consult fee she gave me no info but continued to say I need more info. The following week I called to go in and pay retainer and she said she wasn’t taking my case. It must be nice to sit around and collect retainer fees and n...ot take cases. I would have given a 0 star but it wasn’t available.

Replied last July 02, 2026

This complaint is false and misleading. This individual consulted with me and paid the consultation fee, which is one half my hourly rate. I spent one hour with her and reviewed the documents she brought to me. I asked for additional information, which she provided. I spent an additional hour reviewing the documents she brought to me at no additional charge, and upon review concluded that I could not help her. I explained that I would not have handled her request in the manner in which her former attorney handled it and as such, I declined to take her case. If I thought I could help her, I would have taken the case. This individual did not pay a retainer; she paid a consultation fee which everyone pays if they want to consult with me.
