I rarely write reviews for anything or anybody but John Morgan’s legal work was so excellent I felt it was important to write a review. John Morgan assisted me quickly and efficiently. He was very knowledgeable and gave me good counsel. I was confident he was going to represent me well and he did.

I highly recommend John Morgan if you want good Legal Counsel.

I have personally known Rob Schnatmeier for the past fifteen years, having worked closely with him in the DeKalb County District Attorney’s Office.

Rob is a great trial lawyer and does an excellent job for his clients. Rob and I continued the working relationship that we formed in the District Attorney’s Office and currently work on many cases together.
