Cool as a Cucumber under pressure!
Jen had taken on my case and my original interview with her was fantastic. She was thorough and helped to easily guide the conversation through the pertinent information. Fast forward to a nasty ex parte court date with less than 24 hours to prepare and she was spectacular. Brilliant in and out of the courtroom. Most importantly she had my complete trust. We won the majority of the ex parte case and I owe it all to Jen. I am so grateful she has helped me through these times

I hired Jenni to help me with my divorce. She was always courteous, helpful, knowledgeable in all aspects of family law and responsive. Divorce is a highly stressful situation and Jenni was able to professionally (and on some personal level) take my roller coaster of emotions in stride and provide sound advice and strategy for my case. I would highly recommend Jenni if you find yourself in a situation where you need an attorney.

Above and beyond expectations
A couple of months ago we hired Ms. Hallack to help us with an adoption of my niece, after consulting with several other lawyers, she was the only one to explain to us how the entire process was going to go and made us feel like we had somebody in our corner who was going to turn our dream into reality; and sure thing, a couple of months later, the whole process seemed so effortless and peaceful. She answered and explained every little question we had. She kept us up to date of every step made. The day of the finalization of the entire process, we were in and out of the court room within 2 minutes because she did such a wonderful job that the judge didn't find any ambiguity in our paperwork. I highly recommend Ms. Hallack because our experience with her service was flawless.

Smart, Honest, and fun to work with
First I consulted with Jenni and then I hired her to help me with a troublesome parenting plan. She was very informative, honest, and easy to work with. She is also very accessible and organized. I recommend her to anyone I know that needs a Family Law attorney

Repeat client
I've been a client of Jen's for several years now, and have been represented by her twice - once during a custody dispute, and again during a child support dispute. In both cases, I felt completely at ease with the either likely outcome as Jen handled each case with such a level of personal attention, and a sharp grasp of the matters at hand, that my anxiety and fears quickly gave way to the feeling that I truly had someone on my side who legitimately cared about the outcome. Furthermore, in both cases Jen's tenacity, legal savvy, and sincere concern over the outcome led to her snatching key victories from the jaws of defeat. From ensuring my children would be anchored to me via school district assignment to quietly securing favorable tax status, I feel immensely grateful to have had Jen advocating for me and my family. As a single father of three, I won't step foot into another family court without Ms Hallack representing me.

Jen Hallack
Jen Hallack has been our family's lawyer for almost 5 years. She has not only become our lawyer, but she has become a part of our family as well. I truly believe Jen has fought for our family just as hard as she would have fought for her very own. She has an in-depth knowledge of the family's court system, custody laws, establishing Parenting Plans and child support. Jen keeps it real, does not sugar coat things, but keeps the faith and hope in difficult times. We have been in court several times this summer and every time we walked away with the decisions in our favor. Jen Hallack has been a true God-send in helping to keep our family together.

A knowledgeable lawyer you can trust!
I knew nothing about the divorce process coming into Jenni's office (most people probably don't). I found Jenni to be extremely knowledgeable and easy to talk to/work with. She listened to my needs and concerns and helped me mold a parenting and support plan that I felt comfortable with. Thanks to Jenni the entire process was much less painful than I expected!
