Representation at its BEST!

I retained the services of Mr. Gassner after unsatisfactory success with two other attorneys. He took the reigns with little time to prepared for trial. I was very impressed with his ability to familiarize himself with my case. He made every effort to be available to work with me to prepare. My interactions with him have shown me that he is passionate about his work and clients. Never rushed, he has always taken the time to explain my options and his opinions. He has superior knowledge of family law and is well respected in the courtroom. We are only halfway through the divorce proceedings and the outcomes for me since I hired Mr. Gassner have been in my favor. I am absolutely certain that I couldn’t have picked a better attorney to represent me. I feel confident that he will continue to go above and beyond to represent me for the remaining part of the proceedings. My only wish is that I would have retained him from the beginning.

Great lawyer with a deep knowledgable in domestic and international law

I hired Stephen to help me with a highly complex international custody case. His inherent knowledge of the law, both domestic and international, his awareness and sensitivity of the situation, helped to not only enlighten me, but also the opposing lawyer and most importantly, the judge. Stephen made sure the rights of the children were protected and put in effect. He is a great negotiator. Today, the children are better off because of him and the parents are talking to each other again. Without Stephen's skill set, our situation could've ended in a disaster. Therefore, I can only recommend Stephen to anyone dealing with a complex situation or where communication between parents has come to a halt. If you're looking for a lawyer with integrity whose main concern is upholding the law, Stephen Gassner is the right person for you.

How can a marriage of 20-years or miore divorce? It happens. Lives are intertwined with kids of different ages, supporting two residences on an aggregate income that's enough for only one. Family business has to be controlled by only one spouse (or it gets destroyed. Who will live in the family residence? Must it be sold? Do we have to avoid foreclosure? What about the pension that has been accumulating over the years? How can we get through this and still be friends?

Domestic violence

Whether you are an alleged victim or perpetrator, the court is a risky place to be. Knowing the laws and the legal standards to be proved, is everything. Folks seldom understand their risks going in. They frequently feel they have to win, because they just need to show the evidence... until somebody on the other side says "objection" and their evidence becomes inadmissible - and the court won't consider it. Having a lawyer is everything in these situations.

Great lawyer

Steven is fair and just lawyer and also ruthless Steven gives his best to win the case. He was an awesome divorce lawyer not to have my best interest at heart. When he needed to be tough he was tough and ruthless but fair with the other side. Steven won my case and I was very appreciative of him through the process of the divorce. Direct and straight forward with heart.
