"$5000 Paid, No Results, No Accountability" I hired Caitlin Koestner and paid a $5000 retainer to help with a straightforward custody issue. I am a responsible father with joint custody, simply trying to secure fair parenting time with my son. We were never married, there were no property issues, and no financial entanglements. This was a basic request for shared time. What I got instead was minimal communication, no court filings made on my behalf, and no progress toward resolution. The response from the attorney after I expressed my frustration was to blame the court and the opposing party, while taking no responsibility for the lack of results. I was presented with an unexpected invoice without warning, even though no substantial legal action had occurred. I was also told to file paperwork myself to continue without her. This entire experience has been disappointing and disheartening. I came to Caitlin for support in one of the most important battles of my life — the right to be present in my son’s life — and I was left feeling like I had to do it all myself. If you are a parent seeking real advocacy, honest communication, and someone who will fight for your rights, I strongly suggest looking elsewhere.

I cannot express enough gratitude for Caitlin Coestner's exceptional legal expertise and unwavering support throughout my case. From the outset, Caitlin demonstrated the utmost professionalism and kindness, handling my case with a level of diligence that exceeded my expectations. Navigating a state change, particularly from California to Florida, is known to be a formidable legal challenge. However, Caitlin not only accepted the challenge but triumphed with remarkable skill and determination. Her legal acumen is truly impressive, and it was evident that she had a deep understanding of the complexities involved. Caitlin's intelligence and strategic approach to the case were evident at every step. Her fees were reasonable, and she displayed a commendable level of financial responsibility, ensuring that our funds were spent judiciously and conservatively. This conscientious approach set her apart in my experience with legal professionals. What truly stood out for me was Caitlin's unparalleled ability to listen and comprehend the nuances of our situation. She was the first attorney who not only heard my concerns but genuinely understood them. This level of empathy and understanding translated into her dedicated advocacy for us, and I felt genuinely supported throughout the entire process. Caitlin consistently went above and beyond, always meticulously prepared and demonstrating a wealth of experience in family law. Her generosity in waiving the remaining balance on my bill is a testament to her commitment to client satisfaction and genuine care for the well-being of those she represents. In the end, Caitlin delivered the outcome we desired, a testament to her skillful negotiation and legal prowess. I wholeheartedly recommend Caitlin Coestner for anyone seeking a family law attorney who combines expertise with compassion, ensuring that her clients not only receive exceptional legal representation but also a sense of genuine support during challenging times.

We hired Caitlin Koestner back in 2020 to help my sister with her custody issues and ultimately we were very satisfied by how hard Caitlin and the team worked for us.
