This is the second time I was able to work with Hennes & Haight after a car accident. They fought hard to have the other drivers insurance take care of me and my son. I hope to never have an accident again, but if I do, I will always choose Hennes & Haight.

Working with Mark G. Henness after my MVA was truly life-changing. From the very beginning, he made an incredibly overwhelming and scary experience feel manageable. He not only fought to resolve my accident case with professionalism and dedication, but he also made sure I received the medical care and support I needed to genuinely improve my quality of life. His ability to connect me with the right treatment and guide me through every step of the process gave me so much peace during one of the hardest times in my life. (Henness & Haight) What meant the most to me was how much he cared beyond just the legal side of everything. After the accident, I developed real fear and anxiety around driving again, and Mark never made me feel rushed, dismissed, or like “just another case.” He helped me feel supported, protected, and confident while I healed physically and emotionally. Because of his help, I was able to regain trust in myself and overcome my fear of getting back on the road!

Working with these lawyers has been a great experience. They always explained everything to me and got the best settlement that I could get because the other driver had no insurance. I wasn't expecting anything but Henness Haight worked hard for me even when I forgot all about the lawsuit. They were very diligent stayed in touch with me all the time. Great communication! Thank you so much guys!
