I could not have done it alone, and I am very grateful to them.
“I was recently hurt in a really bad car accident. I did not have health insurance, but Cohn & Swartzon helped me to receive greatly needed medical care. They also helped me get a replacement car quickly so that my wife could continue to drive to work while I was at home, getting better. I could not have done it alone, and I am very grateful to them.”

I am very happy to recommend Cohn & Swartzon.
“I am very happy to recommend Cohn & Swartzon. My two young daughters and I were hit by a teenage driver whose vehicle flipped over our SUV. Cohn & Swartzon took care of everything, from dealing with my own insurance to educating me on the importance of getting top-notch medical care. We ended up obtaining much more compensation than we ever thought possible. Thank you so much!”
– Lori G.
I would definitely refer my family and friends.
“I am very happy with the level of service Cohn & Swartzon provided me with during my time of need. I truly did not expect my insurance to cover my legal fees, but I am sure that Attorney Cohn and Attorney Swartzon wrote a great letter to them. I hope that I don’t need an attorney ever again; but if I did, I would go back to Cohn & Swartzon. And I would definitely refer my family and friends.”
