Hear What Our Clients Are Saying About Us:

“I was very pleased with the service and advice you gave us. During red-hot chaos, you were the voice of reason. Although we wanted more–as I imagine each parent does–you correctly advised us of what was do-able for getting a parent to enter into an agreement. The week-to-week arrangement has worked reasonably well and when things start getting crazy, we have a document with teeth in it to get things back on a workable track. One thing I’ve thought about several times since then is that I had never had reason to have an attorney, but now that I have one I can rely on, it feels good and comfortable!” – Sheryl
