Client Testimonials

Client

★★★★★

I have been working with William Sims and Vikki Blake for the past year and a half and I have nothing but positive things to say about both of them. Bill made it easy for me to get through my settlement and overdelivered on his word each and every time. Bill is also a very down to earth guy who is not pushy what-so-ever which really made me feel like I was in good hands throughout the entirety of my claim. I highly recommend Bill Sims for anybody who is going through an injury claim!

Client

They took care of all my needs. Super helpful, friendly, and kind. Communication was huge, and I never felt like I was left in the dark about the details. They really put me at ease during a stressful time in my life. I'd absolutely recommend to my closest friends and family!

I've worked with the attorneys and staff at ZDC for the last 15 years and I'm confident you will find them the best law practice to work with in the Midwest. Professional, dedicated, compassionate, honest, and fair are just a few of the adjectives that come to mind. They are extremely well-versed in all areas of law and are very well respected by their competitors and the court. You will receive the best service available.
