One of the best in NWI
Attorney Semko is very professional, compassionate and was always available to answer any questions and concerns I had. He brought much ease during a very stressful point in my life. Mr. Semko brought an outstanding result with my case. I highly recommend Attorney Semko's law firm!
Jeffrey Charles Semko's Lawyer Endorsements
"I have had the pleasure of working extensively with Jeff both in and out of the courtroom. Among the scores of attorneys I have met and worked with, Jeff stands out as one of the most intelligent, attentive, and effective advocates. While most of his qualities can be ascribed to his innate intelligence, diligence, and conscientiousness, his most favorable traits—in my judgment—come from his heart. He is likely the most kindhearted, most beneficent, most honorable individual one will ever meet. These attributes make Jeff an excellent advocate, an exceptional attorney, and an extraordinary human being."
"Jeff is an experienced criminal defense attorney who knows the law, the judges and the prosecutors in Lake County. If I have a criminal law question in Lake County, or need to refer an existing civil client to a criminal attorney, Jeff is who I recommend."
