The firm changed our lives by maximizing our recovery and getting us the help we needed to recoup our expenses for my medical bills and wages and to allow us to move forward into our lives. My entire family will always be grateful and highly recommend the team at OSC Law. I live in a different state and the accident occurred in a different state where Jim practices. None of these mattered he still delivered for us.

Mike Quillin represented my father up until the time of his passing. Since then I have been working with Mike and his team to pick up where he and father had left off. He has been extremely understanding and kind to me every step of the way. I cannot say enough about Mike and I would recommend him with full confidence that they would be in the best of hands.

Kari was referred to me by a colleague to handle a workers’ compensation claim involving significant permanent injuries. Not only did she get us a complete recovery in the work comp system, she recommended and pursued a civil action against third parties due to the faulty equipment at issue. I have dealt with other work comp attorneys and do not know of anyone else who would have put nearly as much thought, hard work and dedication into our case.

The team at OSC Law is very caring and concerned when it comes to dealing with you on a personal level. They were very interested in what I had to say and told me I could call him night or day, even if it was just to speak about the tragedy that had happened to me. The team at OSC Law was always been honest with me whether it be good news or bad news. I feel as though they were actually sent to me, my guardian angel. Anyone who decides to go with OSC Law can feel very relieved that whatever the outcome is, they did their best to maximize your case. The team at OSC Law walked me through each and every step of the process and explained why whenever it was something they thought was best.

My mom was in a head-on auto accident (not her fault) and required 6 months of rehab and recovery. Mike and the team at OSC Law stepped in on day one and guided the family through this journey. The family dealt with mom’s physical recovery and OSC Law handled the legal and financial aspect. They oversaw all of the insurance negotiations and kept us informed along the way. After all was said and done…..she received a check and all of her medical bills were paid. A settlement check does not remove all of the residual effects of having your 78 year old mother cut out of a car, but at least we have peace of mind that any future needs as a result of this will be met. OSC Law had mom’s best interest at heart.

I am very thankful to Mike for working so hard on my case. He never made me feel like a was pestering him when I called even if I called multiple times in a week. He was always available to speak with me and calm my nerves throughout the entire process until we were able to settle.

If anyone is looking for an attorney who will fight hard for you Mike is the attorney you need on your side. He works hard to get any and every dollar you deserve and I cannot say enough good things about him. The settlement Mr. Shelton was able to get for me and my family has put us back on track and for that I will be forever grateful.

After the tragedy of my 9 year old daughters terrible bicycle accident I was directed to Jim at OSC Law to gain some direction as to possible options for damages around the cause of her severe injuries. Jim came to our home and from the moment I met him I considered him a friend. He and his team were compassionate, caring, honest and candid. He was resourceful, articulate and always made sure I understood what was taking place. He and his team engaged me in all decisions and strategies in my daughters case and never let a call or email go unanswered. I can’t say enough about how Jim handled this case and that isn’t based on the outcome. My daughters case has been over for several years.
