  • “Margaret (Peggy) represented me during my divorce. My ex-husband and I were going to try to do a pro-se divorce on our own. The paperwork was very difficult to navigate. There are huge tax implications if done incorrectly. We had met Peggy prior to our divorce and we both know she is a wonderful person. She was kind, listened, and very talented. She is extremely knowledgeable and does not waste any time.”

  • “I was looking for a highly knowledgable, professional and personable attorney who would take the time to understand my situation, and that is what I found with Margaret (Peggy) Herlitzka. I performed my due diligence and met with three other attorneys in the La Crosse area prior to retaining Peggy for my situation.”
  • “I knew from the beginning that my case was not going to be easy, yet I knew I had a great partner in Attorney Herlitzka. She was not only a great professional, but emotionally supportive, and remained focused on the end result. I will always be grateful I had her to help me through.”
