So very thankful!
Today I spoke with Mr. Baumstark regarding a few concerns in preparation for court. To say he was helpful as well as thorough, would be an understatement. He provided context and professional insight for my concerns & assured each questions was answered before the end of the call. In the event someone needs representation in the near future, I’ll advise them to request a consultation with his office!

Took a case no one would touch...
My journey through the judicial system in Illinois was not easy. My husband was attacked and later died from the injuries. The attacker was charged and after 5 plus years of trial postponements the attacker was acquitted. I couldn't find an attorney that would represent me in the civil suit until I found Luke. Luke took the case knowing it was not a slam dunk. When Joe (the attacker) was acquitted I expected Luke to tell me there was no hope for the civil suit and walk away. Instead Luke searched the court transcripts, connected the dots from the criminal trial and negotiated a settlement for me. During the process Luke kept me informed, he explained the difficulties of the case, what I could expect and really understood how difficult this process was for me. He guided me through the process making sure I didn't settle too soon for too little. The settlement can't bring Don back, nothing can. But now my family and I have closure and we can move forward. Luke, I can't thank you enough for being an excellent attorney and a caring person. Nelka

Thorough, responsive and committed
Luke stepped up to take on my sister's civil suit when her attorney became a judge and no one else was interested in taking on the challenge. The matter was complex and Luke's thoroughness in reviewing the statements and findings resulted in his being able to put together a solid case to win. Further, he guided my sister in the settlement negotiations to be sure she didn't settle too soon for too little. Beyond his legal expertise, Luke was personable and helped my sister through this very emotional period listening to her and guiding you throughout the process. Luke is a true partner from start to finish.

I found my self in a position that could have easily turned into a major legal problem potentially criminal. Luke was recommended to me by another attorney for his ability to work through issues that could be construed as white collar crime. Luke counseled me to work through the issue and suggested a legal option that allowed me to share my story with authorities in a manner that would allow the truth to be shared without repercussions. He kept me calm and on track through a very difficult stretch in my life. Luke is an outstanding and knowledgeable attorney.
