See What Our Clients Have to Say About Us…
“Could Not Have Asked for a Better Firm” (Truck Accident)
We could not have asked for a better firm to represent us. Baum, Hedlund, Aristei & Goldman was the peak of professionalism. They were always quick to respond and always proved they were in the corner with us; we were a part of the team. It was obvious from the responses of the defendant’s attorneys and the judges we dealt with that our firm was held in high esteem and was well respected. At all times, the firm was quick to ensure the comfort of my family, whether that was in making sure that depositions were done geographically close to my family or that we got to the airport safely after our meetings. They went above and beyond the lawsuit. They helped navigate through things like car storage and medical bills. They were present at court dates that were not directly involved with the case they were hired to handle. Our firm ensured that we navigated the overwhelming court system with a strong advocate in our corner – during what could have felt insurmountable, they were there! During what was a dark time for our family – they were the light at the end of the tunnel helping us heal and find our way.*
- Peggy D.

“They Genuinely Care About Their Clients” (Wrongful Death - Truck Accident)
I strongly recommend this firm based on my experience of working with them during a very difficult time. They genuinely care about their clients and it shows throughout the firm. Each person that I encountered while dealing with this firm, continuously showed their professionalism and caring attitude. When you are grieving the loss of someone you love, it is comforting to know that you have people who understand your pain, help you through a difficult process and keep you informed. They make sure that you understand the process and are always there to answer your questions. Baum, Hedlund, Aristei & Goldman is definitely “The Best”!*
- Deborah A.
“Our Best Interest Was Always Number One on Your List” (Plane Crash)
Our family would like to express our sincere thanks for the wonderful job you and your staff did for us. On September 21 we lost our son in a plane crash. Also, a special thank you to your Spanish-speaking staff for the extra effort put into this case. The language barrier was never a problem, and we are so very thankful to them. All the money in the world will never bring our son back or take away the pain. Your kind words will always be appreciated along with your hard work. Our families have never met, and in the three years that you handled this case our best interest was always number one on your list. Your name holds much respect in our family.
Once again thank you.

“They Are About Changing the Systems Which Got Us into Trouble in the First Place” (Pharmaceutical Product Liability)
Baum Hedlund is not only amazing attorneys but more importantly, they are activists. They are about changing the systems which got us into trouble in the first place. They understand their role in the process of making change. Attorneys have the fortunate ability to go into the company files during the investigative process. They see the companies’ behaviors and work hard at getting confidential documents declassified that have a true public health benefit.*
- Kim Witczak
“I Cannot Say Enough About How Much They Helped Through a Very Difficult Time” (Aviation)
Baum, Hedlund, Aristei & Goldman is an incredible firm. They are so knowledgeable and efficient and yet still have great soft skills.

I cannot say enough about how much they helped through a very difficult time. If you are not talking to this firm, you are doing yourself a huge disservice.*

“They Went Over and Above What Was Expected” (Truck Accident)
Everyone at Baum, Hedlund, Aristei & Goldman did more than their jobs. They went over and above what was expected. They did and still do make us feel like family instead of clients. They did a fantastic job showing the jury what an amazing young man our son Danny was. We would recommend them to anyone looking for an attorney.*
- Mary Brumfield
“Thank You for Being Warriors” (Pharmaceutical Product Liability)
Where other firms weren't willing to take the risk of representing families in a similarly tragic situation as ours, this firm has rallied in our defense to take on a very difficult, one-of-a-kind lawsuit against a major pharm company. While I understand that this case is complex, I am so grateful that this firm has risen up, swords in hands, to fight for justice on behalf of our son and daughters. Thank you for being our warriors!
